APPLICATION AND USE
NR9000 is a digital controller for 2- or 4-pipe terminal units (eg. Fan
Coil) with ON/OFF, 3-POINT floating or modulating control valves as
well as with 3-speed or modulating fan. NR9000 is equipped with
MODBUS (SLAVE) communication protocol enabling the communication with other MODBUS devices (MASTER).
NR9000 is composed by a M6 DIN rail unit and a remote terminal
(NR9000-RT) with integrated room terminal sensor. It is possible to use
the NR9000-TC remote control (optional) to set a daily switching on
and switching off; time table control can be carried out through the
supervisory system too.
NR9000-RT is the remote terminal which can be connected to the
controller (further details on page 16).
NR9000 can be connected to a receiver module (NR9000-RX, technical characteristics on page 18) and controlled by a infrared remote
control (NR9000-TC, technical characteristics on page 17).

NR9000 outputs
• 4 TRIAC Outputs to drive 3P valves (HOT valve and COOL valve).
Contact Rating 24-250V 4 A;
• 3 RELAY Outputs to drive 3 speed FAN (V1, V2, V3). Contact Rating 24..250V 8 A;
• 2 Analogue Output 0-10V to drive proportional valves. It is possible to use 0-10V outputs to drive a modulating FAN plus modulating valves in sequence (0-5/6-10);
• 2 Open Collector Outputs: OC1 and OC2. They have a maximum load of 18mA and can be used to drive 12Vdc relays
whose maximum power is 220mW and winding resistance >=
640Ohm (ref. Controlli relay module mod. DGSRMV);
• OC1 output follows the ON/OFF input and it can be used,
through an external relay, to enable electrical loads. If the
local operation mode is enabled (through controller password) OC1 follows the input DI2 (override turn off), so if DI2
is open, OC1 is ON too, instead if DI2 input is closed, OC1 is
OFF too. If the local operation mode is disabled, OC1 follows the value set at 9011 ModBus address;
• OC2 output is used to enable auxiliary functions described
in the “Controller functions” paragraph. If the temperature
sensor S3 is present, the ON/OFF auxiliary loop which controls OC2 will be automatically enabled; otherwise it is possible to enable the electrical coil in emergency (through
controller password) which controls OC2. If the sensor S3
is not present, OC2 follows the value set at 9013 ModBus
address;
• 1 Bus to connect remote terminal NR9000-RT;
• 1 Bus Modbus to connect supervisor system;
• 1 Bus Link to connect IO expansion;
• 1 communication connector with infrared receiver module

MAINTENANCE
NR9000 are suitable for mounting on a DIN rail with a quick coupling.
Connections shall be in compliance with existing rules and using max
2,5mm2 cross section wires for J1 and J2 terminals and 1,5mm2 cross
section wires for J3 and J4.
To use wire terminals on power supply wires follow the instructions in
order to prevent accidental contacts between cables at different
voltages in case of wrong installation.
The main power is fully isolated but we suggest to install a protection
device compliant to existing national rules with a 125mA intervention
threshold and a minimum 3mm contact opening. The device is not
supplied with the product.
To use the infrared remote control (NR9000-TC) it is necessary to connect NR9000 to the receiver module NR9000-RX through the cable
supplied with the controller.
The connection port of the receiver module is placed on the upper
side of the NR9000 controller. The receiver can be installed in the
range of the infrared remote control through the double-side tape
supplied with the receiver. The infrared remote control NR9000TC is
powered by 2 AAA batteries (included) and it is equipped with a
support for wall mounting (further information on page 17).
The controller is maintenance free.

OPERATION
room 1
The internally stored parameters used by the controller during operation can be changed using NR9000-RT Remote Sensor or using
a Supervisory System (MODBUS protocol). Remote Sensor NR9000-RT
allows to change the operation mode, the set point and the fan
speed; all other parameters can be modified only through the supervisory system or the dedicated configuration tool. The controller
can operate also without the Remote Sensor using a dedicated analogue input (Return Sensor).
link bus
controller
expansions
The controller will consider the data acquired by the Sensor and by
the Supervisory system (if present) and will perform a P or PI or PID
regulation to drive the valves and the fan.
The controller can operate also without NR9000-RT and supervisory
system (Modbus). In this case the room temperature is measured by
the return sensor and thanks to the remote selector it is possible to set
the correction of the temperature. In this configuration, the control
parameters can be changed only through a dedicated configuration tool.
The controller can be controlled by an infrared remote control
(NR9000-TC). The remote control is equipped with a wide display and
supplied together with batteries and frame for wall mounting. It allows to set the temperature in the range 10T30°C, the programming
of a daily switching on and switching off and the set of the operation
mode (ventilation only, heating only, cooling only and automatic).
In case both remote control and remote terminal are present together, the controller will follow the settings received by the last device. In
case the last control is sent by the remote control, the information of
the remote terminal will be overwritten too.

PC Supervisor: configuration tool “Configuratore NR9000” downloadable from www.controlli.eu site; in this case it is possible to
connect up to 250 controllers. It is possible to use also Micronet
View or Touch Screen GTO series on demand getting in touch
with our technical dept.; in this case it is possible to connect up
to 48 controllers.
ModBus - RS485 Connection
The RS485 network is implemented with a 3-conductor cable, which
will be later identified as “+” (pin 23), “-” (pin 24) and “GND” (pin 25).
For wiring is suggested Belden®, model 8762.
For “disturbed” areas is suggested a Belden®, model 3106A using the
twisted pair to connect the “+” and “-“, the reference wire to connect to “GND” and the shield to connect to ground.
Alternatively you can use a cable with the following electrical and
mechanical characteristics:
•
•
•
•
AWG 20/22;
characteristic impedance of 120Ω;
copper wire, “plait” type, twisted;
shielded braided and insulated;
The shield must be connected to controller GND (pin 25).
The network must be wired only in accordance with the principle
shown here, called “daisy chain” (the device is composed by a single RS485 port). Star connections are not allowed.

For proper network cabling is recommended to take the following
precautions:
CONTROLLER FUNCTIONS
1.
Summer/Winter Changeover
The summer/winter changeover is used by the controller to reverse
the action (Hot/Cold) in 2-pipe systems: the temperature set in
economy mode will be increased with the set correction during summer and decreased during winter. This information can be defined
through a dedicated digital input or via parameter and it can be set
by the supervisory system or by a configuration tool using MODBUS
protocol.
N.B: by default Summer/Winter changeover is set by local mode; in
plants equipped with a supervisory system it has to be preconfigured
by remote mode;
Do not use different types of cable to achieve the same network, but always use only the same type of cable;
2. The network cable carries out safety voltage signals (SELV) and
must not be wired together with dangerous voltage signals
(e.g., 230Vac) or carriers of high currents, especially if in alternating current. Also avoid parallel paths to these power cables;
3. Wire the cable lying avoiding kinks, narrow bending radii and
unnecessary wrapping in hanks or skeins;
4. Do not twist the cable cord around the power conductors and,
if they should cross, consider an intersection at 90 ° between the
cable and these conductors;
5. Keep away from sources of electromagnetic field in particular
by large motors, electrical cabinet, reactors for neon, all types
of antennas;
6. Do not pull the power cable exceeds 110N (11.3kg) to prevent
ironing;
7. Assess in advance the route so that it will be as short as possible
and note addresses of connected instruments with particular
reference to its location in the orderly sequence. This can be
very useful in maintenance; we recommend to note the Modbus Address on the product label.
8. Do not reverse the polarity “+” and “-” of the connection terminals;
9. Avoid short lengths of cable terminations in connection tools
to make a maintenance without tearing or flues of the cables
possible;
10. Identify start and ending terminations and avoid cuts “open”;
Terminating transistors and network polarization
The slew rate control, mutual function in our 485 transceiver and the
limited baud rate to 9600 baud make the terminating resistors not
necessary.
RS485 network needs of polarization typically in charge of the master
device; the controller doesn’t have polarization resistors.
The transceiver used by the controller allows to drive up to 256 points.
RS485 standards require a maximum length of 1200m and/or 32 devices on the network.
It should be noted that more limits are exceeded, higher is the probability that problems in communication arise. The phenomenon is not
systematic and may not occur. Conversely, in case problems should
arise and none of the points mentioned in this paragraph has solved
them, it is recommended to connect a repeater (CONV RS485-RIP),
as shown in the picture below:

N.B.: Connect the repeater if cables length exceeds 1200m or if devices are more than 32.
Operation modes
NR9000 works with 3 different operation modes:
•
•
•
COMFORT: the controller will control the temperature (driving
valves and fan) to satisfy the Comfort Temperature Set.
ECONOMY: the controller will control the temperature to satisfy
the Economy Temperature Set.
FROST PROTECTION: the controller is normally OFF; just during
winter operation it works with a set fixed at 8°C and heating
function only.
1st Issue rev. c
Initial Valve position
To drive a 3-point actuator is necessary to place the actuator in a
specific position. Each time the controller is powered up, the actuator will be driven in the closing position for a time equal to the overall
travel time plus 33%.
Cut-off
This function is used to stop the control of the 3 points actuator after
the overall travel time plus 33%. This function is used to ensure the
correct valve closing and to reduce the noise.
The function can be disabled by the supervisory system. In this case
at its stroke end the actuator will be powered indefinitely.
Window contact
This function is used to save energy when a Normally Closed contact
is opened (Open Window). In this case the controller will change
the operation mode from Comfort to Economy. When the window is
open, if the minimum fan speed or the air recirculation functions are
enabled, the fan will be anyway turned off when the set is reached.
Hot/Cold launch
This function is used to avoid the introduction of cold or hot air in the
ambient by delaying (for a set time) the fan start. To disable the
function, set the time = 0.
“Disposal”
The “Disposal” function is useful both for the hot and the cold channel and it helps to take off the energy stored in the fan coil radiator
by delaying the fan turning off.
To disable the function, set the time = 0.
Minimum speed activation
This function is used to prevent air stratification, especially when using
the Return Sensor, as it could be very low sensitive to temperature
variation that occurs at man’s height. A continuous air movement
helps to avoid /reduce air stratification and to optimize the regulation.
If the fan is connected to the relay output, it is necessary to set the
“minimum fan speed” parameter at 1. A system configuration with
Proportional Fan requires setting the minimum speed in % of the control value (0 - 10V), therefore, if the fan is connected to the 0-10V
output, it is necessary to set the “minimum fan speed” parameter
at a value between 0 and 50. In both cases the 0 value disables the
function. To disable this function, set 0 as minimum speed.
Auxiliary regulation ON/OFF (P action)
This function can be automatically enable when the sensor in position S3 is connected. If the remote set in S4 is connected, it is possible
to have a set in the range 10-30°C, otherwise it can be set through
the supervisory system together with the dead zone.
If the supervisory system is not present , this function will be carried on
at fixed point 20°C with dead zone = 1K. The output will be available
in OC2 and it will exclude the management of the electrical coil.
Air recirculation function
This function manages the minimum fan speed. It is enabled setting a
“period” and a “minimum speed” different from zero. When the “period” will be passed, the fan will be enabled at the minimum speed
for the time (minutes) set.

Electrical Coil
Electrical Coil function can be enabled in the configuration tool as
“emergency”.
The output provides an open collector signal (OC2) (with reference
to signal pin 30, +12V) to control an external auxiliary relay.
The output is activated when the room temperature is lower than:
“hot” operation set - Proportional Band - 1°C
and it goes off when the room temperature is higher than:
“hot” operation set - proportional band
Electrical Coil in “emergency” mode:
Control modes
NR9000 works with 7 different control modes selectable via dip switch
or by supervisory system:
ON/OFF Valves and 3-speed fan (“FAST” operation mode - Operation Diagram 1).
2. ON/OFF Valves and 3-speed fan (Operation Diagram 2).
3. 3-point Valves and 3-speed fan (Operation Diagram 3).
4. ON/OFF Valves and 1-speed fan (Operation Diagram 4).

7b. 4-pipe plant: Sequence Valves 0-5/6-10V and Modulating Fan
(0-10V) (Operation Diagram 7b).
1.
In case of use of 3-speed fans (3 relays), the 0-10V outputs are always
available and they follow the ON-OFF or 3-point valves characteristics.
The diagrams of the valves and fans share the Set point, instead proportional bands and hysteresis can be set independently.
Time table by remote control
It is possible to program a daily switching on and switching off
through the use of the optionals NR9000-TC infrared remote control
and NR9000-RX infrared receiver module (for further information look
at pages 17-18).

It is possible to enable the functions hot/cold launch, “disposal” and
minimum speed activation with a priority over normal operation defined by the diagrams.

DIP switches from 1 to 4 can be used to set MODBUS devices address
(up to 14) without the use of the configuration tool and to set the
controller in expansion mode duplicating the outputs.
If DIP 1-4 are all ON the controller is configured as expansion, duplicating the master controller outputs connected to the remote sensor
(NR9000-RT) and/or to the supervisory system.
If DIP switches 1 to 4 are all OFF the default ModBus address is 1 (factory eeprom setting).
In case of more than 14 devices, configuration can be carried out
via supervisory system or using a configuration tool via Modbus protocol.
DIP from 5 to 7 are used to select the operation diagram.
If DIP 5 to 7 are OFF the default operation diagram is nr. 2 - ON/OFF
Valves and 3 Speed FAN (factory eeprom setting).
DIP 8 is used to select 2/4 pipe system.
If DIP 8 is OFF the system is 2 pipe (factory eeprom setting).
Parameters set by DIP have the priority over the supervisory system. It
is possible to disable the DIP switch setting by ModBus.
It is necessary to power down and power up the controller in case of
any change in DIP switches configuration.

NR9000-RX RECEIVER MODULE
DIMENSIONS [mm]
For operation with remote control NR9000-TC it is necessary to connect the receiver module NR9000-RX to the controller NR9000 through
the flat cable supplied with it using the connection port placed on
the upper side of the controller.
NR9000
The receiver module is equipped with 2 signalling LEDs:
•
•
GREEN LED to show the controller status (LED ON = controller ON,
LED OFF = controller OFF);
YELLOW LED to show the time table status (LED ON = time table
enabled, LED OFF = time table disabled).
The GREEN and YELLOW LED briefly blink when they receive a signal
coming from the remote control.
Further than the two LEDs the receiver module is equipped with a
button to override the switching on and switching off of the controller. If time table are enabled, by pressing the button they will be
disabled.
