Product information
1.1 Usage
The ZONE module is used for the activation of the zone damper, modulating or on/off
control of the zone damper, and automatic override of the VEX to Comfort level when
the module’s inputs are activated.
1.2 Positioning and fitting the ZONE module
Use the screw holes in the corners of the module’s fitting box to fix the ZONE module in
position.
Position the module in the most appropriate place, for example close to the zone damper
or close to the VEX unit.
When positioning the module, please note that the maximum cable length of the EON
bus is 50 m. The length of the other cables between the ZONE module and connected
units should not exceed 50 m.

Comments
The supply voltage for the ZONE module is supplied via the EON bus. The maximum
permitted combined power supply for all modules is 400 mA.
The ZONE module also features terminals to provide a power supply for the sensors
(e.g. CO2 sensors, humidity sensors and PIR sensors) and for supplying power to
actuators (such as damper and valve motors).

Installation

External power
supply
If the total power consumption required by the actuators and sensors is higher than 400
mA, an external power supply must be used for one or more of the units connected.
The external power supply used must be a safety transformer (cf. EN60 742). This
power supply must not be separately grounded if it is connected to a 0V terminal on the
ZONE module.

2.2 Connection of EON bus
Connect the EON bus as shown in the diagram below
To see how to connect a shielded cable, please refer to section “4.3.5 Connection of
shielded cable to EON-BUS” in the instructions for the VEX unit.
NB.
All EON modules must be connected in series – like a “Daisy-chain” – from the
connection box.
The total length of the EON connection must not exceed 50 m (see chapter 4, section:
“Wiring diagram” in the instructions for the VEX unit).

2.3 Connection and use of analogue input
The analogue input is used to start and override the VEX unit to Comfort Operation when
the pre-programmed change limit (4.0 V) is exceeded, irrespective of whether the clock
setting of the unit is Economy/Standby or Comfort.
The input is equipped with a timer function that sets the minimum operating time for the
unit to 30 min. – regardless of whether the change limit is only briefly exceeded.
Connection
Use the following terminals to connect the sensor to the analogue input.

The output signal of the CO2 sensor is: 0…2000 ppm = 0…10 V.
The VEX unit will switch to Comfort Operation when the CO2 measurement exceeds
4V = 2000 ppm x 4V = 800 ppm

2.4 Connection and use of analogue output
The analogue output is used to transfer the analogue signal from the ZONE-module’s
analogue input.
The output signal can, for example, be used for the regulation damper or other actuators.

The output signal of the CO2 sensor is: 0…2000 ppm = 0…10 V.
The regulation damper will follow the CO2 signal, which will thus be fully open when the
CO2 value is 2000 ppm.

2.5 Connection and use of digital input
The digital input is used to start and override the VEX unit to Comfort Operation when
the input is activated – irrespective of whether the clock setting of the unit is Economy/
Standby or Comfort.

Use of digital input is used to start the VEX unit and/or override it to Comfort Operation.
If more than one PIR sensor is to be connected to the same ZONE module, the relay
contacts in the PIR sensors are to be connected in parallel (max. 4 sensors).
2.6 Optional simultaneous connection of EON-TOUCH Panel
If the same address is used for the ZONE module and the EON-TOUCH module with
timer function (FUNCTION 1), activation of the digital input will activate the timer
function.
NB.

•
The TOUCH panel cannot be deactivated if the ZONE module input is activated.
TOUCH panels set to a master function are not suitable for ZONE control
(see chapter 4, section: “Setting the address and function of the TOUCH panel”
in the instructions for the VEX100)

2.7 Connection and use of digital relay output
The digital output is used to open an On/Off Zone damper.
The damper opens when …
• the ZONE module’s inputs are activated, resulting in a switch to Comfort
Operation.
• a TOUCH panel with the same address is activated.
• night-time cooling is activated.
NB.
The relay will not be activated until the unit is operating.
The relay output is a voltage-free switch. The ZONE module cannot normally provide
the power supply for connected dampers. An external power supply should be used.

3.1 Setting the address
If more than one ZONE module is connected, each module must have its own
address. No more than 8 modules can be connected.
NB.
After the required settings have been entered, disconnect the power supply at the main
switch and then restart the unit. In addition, fill out the label on top of the module.
The EON-ZONE module and the address number are detected automatically when
electrical supply is connected to the VEX unit.
3.2 Controlling the connection
NB.
The DISPLAY panel must be set at specialist or technician level before the control
procedure can be carried out (see chapter 5, section: “ Switch between user modes” in
the VEX100 instructions). To find out how to switch between user levels, please refer to
the instructions for the VEX.
