EXcon zone control

EXcon zone control

Zone control of up to four zones per unit. This allows the optimum ventilation principle to be employed in each room (zone).

An example might be a car workshop with four different rooms, such as workshop, office, stores and showroom, each of which has different requirements for temperature, humidity and air changes.

See full-size illustration in the section "Introduction to zone control" below.


Introduction to zone control


Zone control makes it possible to control ventilation in up to four different VAV/CAV zones directly from the VEX4000 unit using EXcon Master.

This is perfect for smaller installations with zone where different rooms have different requirements for the indoor climate, e.g. a car repair workshop with four rooms:
a workshop, office, store and showroom. These four rooms will have different requirements for setpoint temperature, humidity, CO2 and timer programs. Zone control will here permit
the requirements to be fulfilled in each room.

Zone control can be used for control of:

  • VAV dampers
  • Cooling and heating valves
  • Humidity
  • VOC/CO2
  • Room temperature cooling

By fitting a switch on the window, zone management also allows monitoring and regulating depending on whether a window is open or closed, e.g. the VAV damper can close if the widow is opened.

The zone module is available in two variants

Zone modules that be purchased are available in two variants, A and M. This makes the zone management flexible, depending on whether it is traditional 0–10 V components or modbus components that you want to connect. The modules can also be combined if both types are needed in the installation.

Zone Module A:

Zone Module M:


A zone module A can control the VAV damper and valve motors with an analogue 0–10 V signal.


A zone module M is used to control the modbus VAV damper and valve motors. 



All of the zone modes are easily configured within the EXcon web server, where you can set the conditions individually for each zone. You can also get an overview of the zone status, where all configured zones can be monitored at the same time.

Zone control, configuration options

Example of zone control configuration

A zone module can control:

  • VAV damper in the extraction air duct
  • A VAV damper in the supply air duct
  • An actuator for heating coil
  • An actuator for cooling coil

Regulating components that can be fitted:

  • VOC/CO2 sensor
  • RH humidity sensor
  • Window or frost switch
  • PIR sensor
  • Room temperature sensor
  • Supply air temperature sensor
  • RPT-20T room touch panel

 Installation example - zone setup

Shown here is an example of a zone control set-up in a car repair shop with three rooms:

  • Workshop
  • Offices
  • Showroom

Installation example - zone setup status

For every configured zone, the user is able to obtain a complete status of all of the connected components, so that current temperature, CO2 and humidity levels, heating or cooling can be read together.
