FCU EC Fan WT2
Fan Coil Unit - EC Fan - Waterside 2 Pipe and 1 thermic valve.
The IQeco standard strategy controls a fan coil unit’s heat/cool outputs, and electronically commutated fan, in response to a
thermistor temperature sensor with a local setpoint knob and a local switch input (window contact, pushbutton, or Passive Infra Red
movement detector input). The WT2 strategy is for waterside 2 pipe units controlling 1 thermic valve actuator. The strategy is
designed to work with TB/TS Trend Thermistor Room Sensors. The strategy supports the fitting of a WMB Room Display module
without further configuration.
The strategy is designed for use with an IQeco31 and is part of the Plus library.
Order code: IQE31/[y]/BAC/ECFANWT2P/[p] where [y] is unit type F = fixed, P = programmable and [p] is the voltage option.
The strategy will also fit IQeco35 and IQeco38 and can be field downloaded to suitable controllers using SET and the standard
solutions.
Inputs
The following real sensors and digital inputs are connected to the input channels and their values can be monitored by text comms
(including IC Comms):
Real Sensors
IN 1: "Local Discharge Air Temp" (S21), the thermistor temperature sensor for the discharge air.
IN 2: "Local Space Temperature" (S22), the thermistor temperature sensor for the space.
IN 3: "Local Setpoint Adjust" (S23), the local setpoint adjustment potentiometer (scaled in the range -0.5 to +0.5). This generates a
setpoint trim in the range -1°C to +1°C or -1°F to +1°F when the knob ‘Offset Range’ (K3) value is set to 2.
Real Digital Inputs
IN 4: "Window Pushbutton PIR" (I24) this input can be either a window contact which opens, or a pushbutton, or PIR (passive infra
red occupation detector) which closes when the occupation override is required. The type of input is defined by switches ‘Window
Mode 1=Enabled’ (W41) and ‘0=Pushbutton 1=PIR’ (W42).

Outputs
OUT 1: "Occupation Relay" (D1), this output is used to switch power to the fan controller.
OUT 5,6: "Heat Cool Valve" (D5), this outputs is connected to a thermic actuator.
OUT 9: "EC Fan" (D9), this is connected to the speed input on the EC fan controller.
Default Operation
The behaviour of the strategy before any configuration of knobs as switches is as follows:
The default occupancy state of the strategy is unoccupied.
In most cases when the controller is powered on the fan outputs will not operate as the space temperature used for control will be
within the deadband for the unoccupied state.
There are 3 ways to take the strategy out of the unoccupied state:
1. Set Knob "Remote Occupancy" (K11) to 0.
2. Using a pushbutton connected to IN4. Press the pushbutton once; this should place the unit into bypass. The bypass state is
active until another press of the pushbutton or timeouts after 30 minutes.
3. Use the service button to put the unit into occupied. Details are in "Service Button - Occupancy" section of the strategy
datasheet.
The fan output may not be operating for the following reasons:
a. The fan anti cycling strategy is active. Once switched off the fan will not start for 5 minutes.
b. Changes to the knobs and switches from the defaults are overriding the fan control.
c. The occupancy state is unoccupied.
WallBus Interface Eco
This Standard Strategy can be used with WMB Units which provide Temperature, Humidity, DewPoint and CO2 values to internal
Strategy Sensor Modules.
When adding WMB Units to the system, 963, IQview8 and IQview4 and other User displays will discover these Sensor Modules and
display them in their lists.
WMB units which do not support Humidity or CO2 values will send a value of 0 to the 963 and user displays.
To stop the User Display from showing any one Sensor Module delete the lable string in that module.
For example to prevent the User Display from showing Humidity, delete the label ( $ parameter ) in sensor 32.
You can delete parameters in fixed strategies using one of these methods: parameter viewer in SET system view, live adjust in SET
drawing view or by a text comms message such as S32($="").
You cannot change connections between modules in this fixed strategy.
The Strategy can operate with the new RS-WMB, RD-WMB and RV-WMB sensors which are detailed inTA201348. It can also
operate with the older version of RD-WMB.
The new WMB sensors are available with options for:
Temperature - RD-WMB T, RS-WMB T, RV-WMB T
Temperature and Humidity RD-WMB TH, RS-WMB TH, RV-WMB TH
Temperature, Humidity and CO2 RD-WMB THC and RS-WMB THV.
The Strategy is designed to operate with RD, RS and RV of all the available types.
Sensors which do not support Humidity or CO2 will continue to scroll through all the variables with a display of 0 unless the input in
the interface module is deleted.
For RD-TH, RS-TH, RV-TH sensors
Delete the PVid in t2I10V to prevent the RD displaying CO2 with the value 0
For RD-T, RS-T, RV-T sensors
Delete the PVid in t2I10V to prevent the RD displaying CO2 with the value 0
Delete the PVid in t2I6V to prevent the RD or RV displaying Humidity with the value 0
Delete the PVid in t2I11Vto prevent the RD or RV displaying Outside Air Temperature with the value 0

FCU EC Fan WT2
The RV sensors have configuration settings such as button graphics and CO2 thresholds. The Strategy does not allow you to link
these settings to strategy. Configuration settings for RV can only be made through the display. See Trend Data sheet TA201354.
For RV and RD meters you can display CO2 from a remote controller by setting up an IC comms to Sensor 34 and deleting the PVid
in t2O4 so that the value in S34 is not overwritten.
This standard solution does not support a CO2 sensor hard wired to the controller.

Role
Adjustments - Items the users may want to change.
Remote Control - Items that are expected to receive IC Comms e.g. frost protection.
Overrides - Items that enable control to be overridden e.g. heating override.
Settings - Items that should be set up during commissioning.
Options - Items that select an option or behaviour e.g. serial parallel fan.
Energy - Items related to energy.
Adjustments
K1 ‘Pushbutton PIR Timeout’, this knob defines the time in minutes for which the activation of the pushbutton/PIR input overrides
the unit into the occupied state. The default value is 30 minutes.
K2 ‘Setpoint Adjust Timeout’, this knob defines the time in minutes for which any setpoint trim will be applied to the setpoint. The
default value is 60 minutes.
K3 ‘Offset Range’, this knob is used to define the range of ‘Local Setpoint Adjust‘ (S23). The ‘Local Setpoint Adjust‘ (S23) is scaled
to give a range of -0.5 to +0.5; this is multiplied by the ‘Offset Range’ to give the setpoint trim which is applied to the ‘Remote
Setpoint’(K14) to produce the ‘Setpoint’ (S3). The default value is 2°C or 2°F producing a value between -1°C to +1°C or -1°F to
+1°F.
K4 ‘OCC Deadband’, this knob defines the difference between the heating and cooling setpoints during occupation. The default
value is 1°C or 2°F.
K5 ‘NOCC Deadband’, this knob defines the difference between the heating and cooling setpoints during non-occupation. The
default value is 25°C or 45°F.
K6 ‘Standby Deadband’, this knob defines the difference between the heating and cooling setpoints during standby. The default
value is 8°C or 15°F.
K7 ‘Heating Setpoint’, this knob defines the heating setpoint when separate setpoints are selected using switch ‘HeatCool Setpoint
1=Separate’ (W36). The default value is 19.5°C or 67°F.
K8 ‘Cooling Setpoint’, this knob defines the cooling setpoint when separate setpoints are selected using switch ‘HeatCool Setpoint
1=Separate’ (W36). The default value is 20.5°C or 69°F.
W1 ‘Unit Bypass Request 1=Active’, this switch is set to ON if the unit is in bypass and can be used to put the unit into or out of
bypass. The default state is OFF.
Remote Control
K11 ‘Remote Occupancy’, this knob defines unit’s occupancy state: 0(Occupied), 1(Unoccupied), 2(Bypass), 3(Standby). It can be
overridden into bypass (equivalent to Occupied within the unit) from any occupation state by the pushbutton or from standby by the
PIR. The state is overridden to unoccupied by the switch ‘Remote Shutdown 1=Shutdown’ (W11) or the window contact (IN24). The
definition of the occupancy states are detailed below under Occupancy States. The default value is 1(Unoccupied).
K12 ‘Remote Space Temperature‘, this knob is used instead of input ‘Local Space Temperature’ (S22) when the input has an out of
limits or read alarm. It can also be used by setting switch ‘Temperature Select 1=Remote’ (W34) to ON. The default value is 22°C or
71°F.
K13 ‘Remote Setpoint Offset‘, this knob is used instead of input ‘Local Setpoint Adjust’ (S23) to provide the setpoint trim. It is added
to the ‘Remote Setpoint’ (K14) when the input (S23) has an out of limits or read alarm. It can also be used by setting switch ‘SP
Offset Select 1=Remote’ (W35). The default value is 0°C or 0°F.
K14 ‘Remote Setpoint‘, this knob is combined with the setpoint trim to provide the ‘Setpoint’ (S3). The default value is 22°C or 71°F.
K15 ‘Remote Fan Speed‘, this knob is used to set the fan speed in the range of range: 0 (off), 1 (low), 2 (medium), 3 (high), or
4(auto). To ensure that the 'Remote Fan Speed' value is used when sensor ‘Local Fan Speed’ (S27) is fitted the switch 'Fan Speed
Select 1=Remote' (W39) must set to ON. The fan will be switched off during non-occupation unless there is heating demand (fabric
protection) which selects low fan speed. The default value is 4(auto).
K19 ‘Water Flow Temperature’, this knob sets the temperature used to calculate the energy consumption of the unit. The default
value is 50°C or 122°F.
W11 ‘Remote Shutdown 1=Shutdown’, this switch when set to ON forces the unit into the unoccupied state, disables cooling, only
allows sub-zero heating, and disables fabric protection during non-occupation. The default state is OFF.
W12 ‘Frost Condition 1=Frost’, this switch when set to ON forces the unit into a frost condition during non-occupation. During the
frost condition the heating demand is fixed at 98%. The default state is OFF.
W15 ‘Summer Mode 1=Summer’, this switch selects the mode used to drive the output ‘Heat Cool Valve’ (D5). If the switch is set to
ON (summer mode) the valve is driven from the cooling demand else the valve is driven from the heating demand. The default state
is OFF.
Knobs Switches 21 - 40
Overrides
K24 ‘Heat Cool Valve Override Value’, this knob sets the value used to drive the heat cool valve output when switch ‘Valve Override
1=Enabled’ (W24) is enabled. The default value is 50%.

K40 ‘Maximum Fan Speed Setpoint’, this knob defines the maximum speed permitted by the EC fan. The default value is 70%.
W31 ‘Service Button Mode 1=Enabled’, this switch when set to ON allows the service button to be used as an input into the
strategy. The default state is ON.
W32 ‘Overrides 0=Disabled 1=Enabled’, this switch when set to ON allows the strategy overrides to be used. The default state is
ON.
W34 ‘Temperature Select 1=Remote’, this switch when set to ON forces the strategy to use the value from knob ‘Remote Space
Temperature‘ (K12) and not sensor ‘Local Space Temperature’ (S22). The default state is OFF.
W35 ‘SP Offset Select 1=Remote’, this switch when set to ON forces the control to use the value from knob ‘Remote Setpoint
Offset‘ (K13) and not sensor ‘Local Setpoint Adjust’ (S23). The default state is OFF.
W36 ‘HeatCool Setpoint 1=Separate’, this switch when set to ON enables the control to use separate setpoints for heating and
cooling use knobs ‘Heating Setpoint’ (K7) and ‘Cooling Setpoint’ (K8). The default state is OFF.
W37 ‘Pushbutton TETS KO 1=Fitted’, this switch when set to ON allows the control to utilise the override pushbutton operation of
the TB/TS/KO range of thermistor room temperature sensors. The default state is OFF.
W39 ‘Fan Speed Select 1=Remote’, this switch when set to ON forces the strategy to use the value from knob ‘Remote Fan Speed‘
(K15) and not sensor ‘Local Fan Speed’ (S27). The default state is OFF.
Knobs Switches >41
Options
W41 ‘Window Mode 1=Enabled’, this switch when set to ON forces the control to treat the digital input ‘Window Pushbutton PIR’
(I24) as a window contact.
W42 ‘0=Pushbutton 1=PIR ‘, this switch is only used when switch ‘Window Mode 1=Enabled’ (W41) is set to OFF. Then the switch
when set to ON treats the digital input ‘Window Pushbutton PIR’ (I24) as a passive infrared detector and when set to OFF treats the
input as a pushbutton. The default state is OFF.
W45 ‘Fan Off at Setpoint 1=Enabled’, this switch when set to ON will disable the fan when the unit is at setpoint and there is no
heating or cooling demand. The default state is OFF.
Energy
K51 ‘ECO Mode Deadband Increase’, this knob defines the value that will be added to the existing deadbands when switch
‘Operating Mode 0=Comfort 1=ECO’ (W51) is set to ON. The default value is 3°C or 7°F.
K52 ‘Power Conversion Factor’, this knob defines the scaling factor that will be multiplied with the heat meter module output to
produce kW. 1kW = 0.948608 Btu/s. The default value is 1 when using kW and 0.948608 when using Btu/s.
W51 ‘Operating Mode 0=Comfort 1=ECO’, this switch when set to ON enables the control to operate in eco mode and increase the
deadband by the value on knob ‘ECO Mode Deadband Increase’ (K51). The default state is ON.
W52 ‘Energy Meter 1=Reset’, this switch when set to ON will reset the energy meter. Once set the control automatically resets the
switch to OFF. The default state is OFF.
Window PushbuttonPIR Operation
The external digital Input ‘Window Pushbutton PIR’ can be used as either a window contact, PIR or Override Pushbutton and its
type configured by Switches ‘0=Pushbutton 1=PIR’ and ‘Window Mode 1=Enabled’’.
In window mode (Switch ‘Window Mode 1=Enabled’ set to ON) the Input ‘Window Pushbutton PIR’ is configured to be a window
contact. When the window contact is open the control will override the unit into Unoccupied.
In pushbutton mode (Switch ‘0=Pushbutton 1=PIR’ set to OFF) the Input ‘Window Pushbutton PIR’ forces the unit into Bypass from
any state for the time set ON Knob ‘Pushbutton PIR Timeout’.
In PIR mode (Switch ‘0=Pushbutton 1=PIR’ set to ON) the Input ‘Window Pushbutton PIR’ will override the unit from Occupied or
Standby into Bypass for at least the time set ON Knob ‘Pushbutton PIR Timeout’.
Within the unit, the Bypass condition is treated the same as Occupied so that although Sensor ‘Occupancy’ shows separate
Occupied and Bypass states, if Bypass is set then Inputs ‘Unit In Bypass’ and ‘Unit Occupied’ will both be set to ON.
The Switch ‘Unit Bypass Request 1=Active’ can be used to stop or start the bypass condition.
When Switch ‘Pushbutton TETS KO 1=Fitted’ is set to ON the external Sensor ‘Local Setpoint Adjust’ out of limits alarm is used to
as the input for PIR or pushbutton override.
Technical Description
A single external digital Input ‘Window Pushbutton PIR’ is used as a window contact, PIR or Override Pushbutton to create a ‘PB
PIR override active’ and ‘Unit interrupt’ digital signals. When used as a PIR or Pushbutton the input is only processed by the
strategy at the rate of the counter module reschedule time. This is to ensure that only one press of the button is reacted to by the
strategy.
The strategy also supports the use of a TE/TS/KO for the override pushbutton using external Sensor ‘Local Setpoint Adjust’ and
Switch ‘Pushbutton TETS KO 1=Fitted’.
Commissioning Details

2. If override is provided by TB/TS/KO set Switch ‘Pushbutton TETS KO 1=Fitted’ to 1.
3. Set the time of Knob ‘Pushbutton PIR Timeout’ for the length of the bypass period required.
Tip.
Input ‘Window Pushbutton PIR’ can be configured as a status monitoring input e.g. filter dirty by changing the E parameter on
function module ‘Input active’ to 100 and setting Switch ‘Window Mode 1=Enabled’ to 0. Remember to change the label on the input
to indicate its function.
Occupancy State
The unit operates in either Occupied, Unoccupied, Bypass, and Standby modes as determined by the ‘Remote Occupancy’ setting.
Occupied:
The unit is on for normal operation and controls to a user defined setpoint. This is Comfort mode as defined in
the European standard EN15500.
Unoccupied:
The unit is off, no fan, heating or cooling. The PIR has no effect although the override pushbutton will override
the unit into bypass. This is Building Protection mode as defined in the European standard EN15500.
Bypass:
The unit has been put into occupation by the override pushbutton or the PIR (occupancy sensor).
Standby:
The unit is activated to reduce its energy consumption. In this mode either the override pushbutton or the PIR
will put the unit back into occupied. This is Economy mode as defined in the European standard EN15500.
Within the unit the Bypass condition is treated the same as Occupied but both inputs ‘Unit In Bypass’ and ‘Unit Occupied’ will be set
to ON.
When Switch ‘Remote Shutdown 1=Shutdown’ is set to ON it will override the unit into unoccupied. The same behaviour occurs if
the unit is in window mode (Switch ‘Window Mode 1=Enabled’ set to ON) and the window contact on Input ‘Window Pushbutton PIR’
is not closed.
Technical Description
A single external digital Input ‘Window Pushbutton PIR’ is used as either a window contact, PIR or Override Pushbutton. The
required occupancy states are decoded to digital signals. 0 = Occupied, 1 = Unoccupied, 2 = Bypass, 3 = Standby. The unit can
also be put in to occupancy using the service pin.
Discharge and Space Temp
Technical Description
With external sensor ‘Local Discharge Air Temp’ fitted the sensor value is gated through to internal sensors ‘Discharge Air
Temperature’. The internal sensor 'Space Temperature' will use the value of either the external sensor 'Room Display Space
Temp', when a Room Display module is fitted, or the value from external sensor ‘Local Space Temperature’, if fitted. If the external
sensor has a ‘Read’ or ‘Out of limit’ alarm the value of input F on the respective gate module will be displayed on the internal
sensor.
Setting switch ‘Temperature Select 1=Remote’ to 1 forces the internal sensor ‘Space Temperature’ to use the value on input F of the
gate module ‘Actual space temperature’.
Heating Cooling Setpoints
The heating and cooling setpoints can be configured to be separately adjusted or calculated. The selected setpoints have half the
current deadband applied as defined by the occupation state. The value of the deadband is increased when not in occupation. The
setpoint can also have an offset (trim) adjustment made locally, that will increase or decrease the required setpoint.
Eco Features
Local offset adjustment is valid for an adjustable time after which it is ignored until a change of the offset value is detected.
The size of the deadband is increased when the unit is in ECO mode.
Technical Description
The setpoint is calculated from Knob ‘Remote Setpoint’ unless Switch ‘HeatCool Setpoint 1=Separate’ is set to 1 when Function
‘Selected heat setpoint’ and Function ‘Selected cool setpoint’ use Knobs ‘Heating Setpoint’ and ‘Cooling Setpoint’ respectively for
they values.
The ‘Heat setpoint’ is calculated by subtracting half the deadband, selected by the mode of occupation, from the value on Function
‘Selected heat setpoint’ and adding any value on Function ‘Setpoint offset’. The ‘Cool setpoint’ is calculated by adding half the
deadband, selected by the mode of occupation, to the value on Function ‘Selected cool setpoint’ and adding any value on Function
‘Setpoint offset’. The ‘Heat setpoint’ and ‘Cool setpoint’ are each halved and combined to provide the ‘Setpoint’.
The normal operation of ‘Setpoint offset’ with the external Sensor ‘Local Setpoint Adjust’ fitted is for the sensor value to be gated
through Function ‘Selected setpoint offset’ and the value of Knob ‘Offset Range’ to be gated through Function ‘Selected offset
range’. If the sensor has a ‘Read’ or ‘Out of limit’ alarm or Switch ‘SP Offset Select 1=Remote’ is set to 1 the strategy gates through
the value of Knob ‘Remote Setpoint Offset’ on Function ‘Selected setpoint offset’ and a value of 1 through Function ‘Selected offset
range’.
If a Room Display module is fitted the strategy will automatically use the value on Knob 'Room Display Setpoint' to calculate any
change in setpoint and feed this through as the offset value.
Any change in the offset value is detected by the strategy and will start Logic timer ‘Adjustment active’. The offset value on Function
‘Selected setpoint offset’ is gated through Function ‘Active setpoint offset’ it is then scaled using the value on Function ‘Selected
FCU EC Fan WT2 Strategy Data Sheet TA201211 Issue 3, 18-Apr-2016

FCU EC Fan WT2
offset range’. Function ‘Setpoint offset’ value is added to the ‘Minimum setpoint’ and ‘Maximum setpoint’ to provide the ‘Heat
setpoint’ and ‘Cool setpoint’ respectively and is set to 0 after the time set on Knob ‘Setpoint Adjust Timeout’ has expired.
Heating Cooling Demands
Heating and cooling demands are calculated by comparing the space temperature with the relevant setpoint. If the space
temperature is below the heating setpoint a heating demand is created and if the space temperature is above the cooling setpoint a
cooling demand is generated, the greater the difference the larger the demand. To prevent hunting of the heating and cooling
demands a deadband is employed to ensure a change equal to half the deadband is detected before a demand is generated or
removed. When the heating or cooling demand reaches 100% the speed of the fan is increased. When a frost condition exists and
the unit state is unoccupied the heating is enabled.
Technical Description
Both heating and cooling sides are controlled by different control loops. The heating loop is enabled whenever ‘Unit interrupt’ is set
to 0 and ‘Summer Mode 1=Summer’ is set to 0. The cooling loop is enabled whenever ‘Unit interrupt’ is set to 0 and ‘Summer Mode
1=Summer’ is set to 1. Both loops are disabled if 'Fan control off selected' is set to 0.
The heating loop compares the ‘Actual space temperature’ with the ‘Heating setpoint’. The proportional + integral (P+I) loop will
modulate the heating output to maintain a constant space temperature. As the temperature decreases below the heating setpoint
the heating output will modulate open. The heating output will be modulated closed as the temperature increases above the heating
setpoint. The loop output is limited to the range 0 to 100%.
The cooling loop compares the ‘Actual space temperature’ with the ‘Cooling setpoint’. The proportional + integral (P+I) loop will
modulate the cooling output to maintain a constant space temperature. As the temperature increases above the cooling setpoint the
cooling output will be modulated open. The cooling output will be modulated closed as the temperature decreases below the cooling
setpoint. The loop output is limited to the range 0 to 100%.
The integral time constant is the time for which the loop output will have added to it an amount equal to product of the error and the
gain (i.e. equal to the proportional part) under conditions of constant error. If the error stays the same for the integral time constant,
the loop output will double and will be 2G(E). The loops have the following default settings: heat loop gain = 6, cool loop gain = -5,
both loop integral time constants = 30 minutes. These settings can be changed by text comms.
The output from the loops (ignoring the integral action) is illustrated by the chart below:
The heating loop will not operate until the ‘Actual space temperature’ drops below the ‘Heating setpoint’ by half the deadband e.g.
Setpoint 22°C (72°F) deadband 4° = 22-2 = 20°C (72-4 = 68°F) during occupation. Similarly for cooling it must rise above the
‘Cooling setpoint’ by half the deadband. The loop gains are set to +6 and -5 by default which gives proportional bands of 16 and 20
°C (°F) and i.e. 100/6 and 100/5. When set to defaults, during occupation, this will give 100% heat at 4°C (39°F), and 100% cool at
44°C (111°F) ignoring the effect of the integral term.
The loop outputs are added together and then split into separate heating and cooling outputs to prevent simultaneous heating and
cooling. The separate demands are rescaled so the demand 0 to 90% drives the relevant valve output between 0 and 100% and the
demand 90 to 100% increases the fan speed. When the heating or cooling demand is greater than 4.5% a respective ‘Heating

FCU EC Fan WT2
required’ or ‘Cooling required’ signal will be set to 1. The ‘Heating required’ or ‘Cooling required’ signals are reset to 0 when the
respective demand falls below 0.5%.
The heating loop is overridden to 98% if the ‘Frost Condition 1=Frost’ is set to 1 and ‘Unit - unoccupied’ is set to 1. This will bring on
the heating if the unit not in summer mode.
Heat Cool Valve
The cooling demand drives the Heat Cool valve when the switch ‘Summer Mode 1=Summer’ is ON when it is OFF the heating
demand is used. A demand of 100% opens the valve fully and a demand of 0% closes the valve. The valve is fully opened when
Switch ‘Water Balance 1=Enabled’ is ON.
Technical Description
The valve can be overridden, providing Switch 'Overrides 0=Disabled 1=Enabled' is set to 1, by setting Switch ‘Valve Override
1=Enabled’ to 1 and adjusting Knob ‘Heat Cool Valve Override Value’ to the required value between 100 and 0. The overrides are
ignored and the valve is fully opened when Switch ‘Water Balance 1=Enabled’ is 1.
Commissioning Details
1. The Heat Cool valve drive time should be set to match the fitted actuator.
Fan Control - Variable Speed
The fan is ON when the occupation state is occupied; bypass or standby and is OFF when unoccupied. The required speed of the
fan is displayed on the sensor ‘Selected Fan Speed’ where 0 = OFF, 1 = Low, 2 = Medium, 3 = High and 4 = Auto. Low speed is the
value set on knob 'Minimum Fan Speed Setpoint' and High speed is the values set on knob 'Maximum Fan Speed Setpoint'.
Medium speed is the mid value between these two setpoints. If the ‘Selected Fan Speed’ is Auto, the fan will normally run at low
speed, but as the fan demand increases, as a result of an increase in the heating or cooling demand, the fan speed will be
increased to meet the demand, similarly the fan speed will be reduced as demand is met. The actual fan speed is displayed on the
sensor ‘Actual EC Fan Speed’ and is a factor of 10 smaller than the demand i.e. Low = 'Minimum Fan Speed Setpoint' = 37 will
display as 3.7. The fan has an anti cycling timer to protect it from excessive restarts.
Eco Features
The fan can be set to switch OFF whenever the unit is at setpoint i.e. no heating or cooling demand by setting Switch ‘Fan Off at
Setpoint 1=Enabled’ to ON. The fan will restart when a heating or cooling demand exists. This is only applicable when the sensor
‘Selected Fan Speed’ is set to Auto (a value of 4).
Technical Description
The fan is enabled when the occupation state is occupied, bypass or standby and the unit interrupt signal is 0. The driver
'Occupation Relay' is enabled during occupation, time delayed based on the controller address, and is intended to be used to
enable the fan controller.
Automatic control is achieved by rescaling the fan demand set between the ‘Minimum Fan Speed Setpoint’ to the ‘Maximum Fan
Speed Setpoint’. When the required to switch off the ‘Minimum Fan Speed Setpoint’ value is replaced with 0.
The fan control can only be overridden when Logic ‘Unit - unoccupied’ is 0 by either Knob ‘Remote Fan Speed’ or the WMB Room
Display module. The strategy selects the correct control depending on which items are present using the WMB Room Display
module ‘I/O2 Failed status’ bit.
The Knob ‘Remote Fan Speed’ is used when its value is less than 4 or when Switch ‘Fan Speed Select 1=Remote’ is set to 1. When
used the knob has precedence over the external WMB Room Display module.
The WMB Room Display module if fitted uses Knob ‘Room Display Fan Speed’ to display and adjust the speed.
The fan control has an anti cycling timer that delays the time to restart after the fan stops thus preventing unwanted cycling of the
fan. When electric heaters are included in the control the fan will run when Logic ‘Electric heat run on required’ is 1.
The fan control can be overridden, providing Switch 'Overrides 0=Disabled 1=Enabled' is set to 1, by setting Switch ‘Fan Override
1=Enabled’ to 1 and adjusting Knob ‘Fan Speed Override Value EC’ to the required value. The anti cycle timer still operates under
these circumstances.
Commissioning Details
1. Set the ‘Minimum Fan Speed Setpoint’
2. Set the ‘Maximum Fan Speed Setpoint’
3. Confirm that Comparator 'Fan enabled' parameter E value is correctly set to indicate that the fan is enabled.
4. The Timer ‘Anti cycle active’ parameter F requires setting to ensure the minimum off time required for anti cycling the fan. 300
seconds = 5 minutes = 12 starts per hour.
5. The switch 'Fan Speed Select 1=Remote’ requires setting to 1 if the WMB Room Display is to be excluded from the control of the
fan.

Service Button - Water balance
Pressing the service button in a predefined sequence, when in service button mode, can initiate behaviour in the strategy to start
and stop water balancing where all the valve outputs are set to 100% or 0% i.e. fully open or fully closed. The function is only
available if Switch ‘Service Button Mode 1=Enabled’ is set to ON. For a full description of service pin mode refer to the Trend
publication TE201089 IQeco Configuration Manual Issue 2 or greater. The service button press sequence for the required behaviour
is as follows;

Technical Description
The service button can be used to initiate behaviour designed in the strategy; to achieve this behaviour the controller must be put
into service button mode. Service button mode has 5 stages Entry, Phase 1, Phase 2, Phase 3 and Exit.
Entry - Press and hold the service button for 2 to 5 seconds. When the service button is released a rapidly flashing comms LED
(green) for one second indicates entry into ‘service button mode’. When the flashing stops this indicates the start of Phase 1.
Phase 1 - This stage lasts 3 seconds and during this time if the service button is not pressed it will mean that a ON condition is
required. If it is pressed then an OFF condition is required. At the end of this stage the comms LED (green) will flash once to
confirm no press and twice to confirm a press. The end of the flashing indicates the start of phase 2.
Phase 2 - This stage lasts 3 seconds and during this time if the service button is not pressed it will mean that the selection in Phase
1 should be applied to the LAN and if it is pressed then it will be applied to the UNIT. At the end of this stage the comms LED
(green) will flash once to confirm no press and twice to confirm a press. The end of the flashing indicates the start of phase 3.
Phase 3 - This stage lasts 3 seconds and during this time if the service button is not pressed it will mean that a Water Balance
selection is required and if it is pressed then it will indicate that an Occupancy selection is required. At the end of this stage the
comms LED (green) will flash once to confirm no press and twice to confirm a press. The end of the flashing indicates the start of
the Exit stage.
Exit - This stage lasts for 3 seconds and starts with a rapidly flashing comms LED (green). During this stage if the service button is
not pressed then the service button mode will expire without any further action. The service button must be pressed to confirm the
selections made in phases 1, 2 and 3. Once pressed the LED will go out for the remainder of the stage and the virtual input channel
selected by the choices made during phases 1, 2 and 3 will go ON for one pass of the sequence table. The virtual input channel is
allocated to a Digital Input module to make it available to be used by the strategy. At the end of this stage the service button mode
will be automatically exited and the LED and service button return to their normal operation.
Service Button - Occupancy
Pressing the service button in a predefined sequence, when in service button mode, can initiate behaviour in the strategy to change
the occupancy state to occupied or unoccupied. The function is only available if Switch ‘Service Button Mode 1=Enabled’ is set to
ON. For a full description of service pin mode refer to the Trend publication TE201089 IQeco Configuration Manual Issue 2 or
greater. The service button press sequence for the required behaviour is as follows;

selections made in phases 1, 2 and 3. Once pressed the LED will go out for the remainder of the stage and the virtual input channel
selected by the choices made during phases 1, 2 and 3 will go ON for one pass of the sequence table. The virtual input channel is

will be automatically exited and the LED and service button return to their normal operation.
Virtual Energy Meter
An estimation of the unit’s energy consumption is calculated by the controller and can be viewed on Sensor ‘Unit Energy Meter’. The
consumption is measured over a 30 minute period starting from 0 and increasing until the end of the period when the value is stored
in the controller. The controller stores the last 200 values and these can be viewed from suitable displays or supervisory software
e.g. IQView and 963. The calculation totals the estimated energy used by the heat exchangers and the energy consumed by the fan
and by the loads switched by the relay output. The accuracy of the calculation depends on the values configured in the controller
however the default values supplied provide for a like for like comparison between similar units.
Technical Description
The estimated calculations use the heat meter module for the power being provided by the heat exchangers. This power is then
added to the power of the fan and using an integrator module the power consumed is calculated over the period of 15, 30 (default)
or 60 minutes depending on the configuration of the strategy.
Heat exchanger power estimation formula.
Heating Power = (Heating medium temperature - Space temperature) * Coil duty * Valve position / 100
Power kW (D) = (Water Supply Temp DegC (E) - Space Temp DegC (F)) * Coil Duty kW/degK (G) * Valve Position %(0-100)(H) *
0.01 (constant)(I)
Power Btu/s (D) = (Water Supply Temp DegF (F) - Space Temp DegF (E)) * Coil Duty Btu/sDegF (G) * Valve Position %(0-100)(H) *
0.01 (constant)(I)
Cooling Power = (Space temperature - Cooling medium temperature) * Coil duty * Valve position / 100
Power kW (D) = (Space Temp (E) - Water Supply Temp (F)) * Coil Duty kW/degK (G) * Valve Position %(0-100)(H) * 0.01
(constant)(I)
Power Btu/s (D) = (Space Temp DegF (E) - Water Supply Temp DegF (F)) * Coil Duty Btu/sDegF (G) * Valve Position %(0-100)(H) *
0.01 (constant)(I)
To improve the accuracy of the estimation the following parameters should be configured with the correct value for the unit:
Function module
Parameter
Units
‘Heating coil duty max speed’ F
kW/degK (Btu/sDegF)
‘Cooling coil duty max speed’ F
kW/degK (Btu/sDegF)
‘Fan duty max speed’
F
kW
‘Occupation relay duty’
F
kW
The output 'Occupation Relay' is intended to be the relay that switches the power to the EC fan controller and the value of
‘Occupation relay duty’ is the duty when the fan controller is energised. The values calculated are linear and therefore are only an
estimate.
The period the integrator uses for the calculation can be changed by amending the arguments in parameter K on Logic module
‘Meter reset’: F = 15 minutes, G = 30 minutes and H = 60 minutes. If the Logic is changed then the period parameter P on plot
module ‘Unit Energy Meter’ should also be changed to match: 1 = 15 minutes, 7 = 30 minutes and 0 = 60 minutes.
Useful conversions:
1 kW = 0.948608 Btu/s
1 hp = 0.7074163 Btu/s
1 Btu/h/3600 = 1 Btu/s
Commissioning Details
1. Set the values of the duty for the coils.
2. Set the values of the duty for the fan.
3. Set the value of the duty for the occupation relay.
4. Confirm the water flow temperatures are received from the main plant.
IC Comms and Alarm Group
Technical Description
The IC Comms are configured for master slave operation directed to standard knobs and switches one or all of the following: Space
Temperature, Setpoint, Occupancy and Fan Speed. The IC Comms modules use attribute 3 and to prohibit unwanted
communications are, by default, disabled.
One alarm group route and destination modules are configured to send Trend text alarms to address 1 on the local lan, this would
normally be the IQ3/BINC VCNC port 10001. To prohibit unwanted alarms the route, by default, is disabled.
Analogue node 99 is provided so a value can be placed in it to indicate the state of the unit during commissioning and witnessing.
The meaning of the value is user defined. It is suggested a bit state approach be used where values 1, 2, 4, 8 ,16 etc each
indicating a separate operation. Summing the values provide a state of the unit.
Suggested values:
1=
Addressed,
2=
Attributes Set,
4=

The behaviour of the strategy before any configuration of knobs and switches is as follows:
Local Space Temperature
To Page(s) 9,
The default occupancy state of the strategy is unoccupied.
In most cases when the controller is powered on the fan outputs will not operate as the
space temperature used for control will be within the deadband for the unoccupied state.
There are 3 ways to take the strategy out of the unoccupied state:
1. Set Knob “Remote Occupancy” (K11) to 0.
2. Using a pushbutton connected to IN4.
Press the pushbutton once; this should place the unit into bypass.
The bypass state is active until another press of the pushbutton or timeouts after 30 minutes.
3. Use the service button to put the unit into occupied.
Details are in “Service Button - Occupancy” section of the strategy datasheet.

A99 State Holder can hold a value to indicate the state of the unit.
The meaning of the value is user defined.
It is suggested a bit state approach be used where values 1, 2, 4, 8 ,16 etc
