Functional description

The module for zone expansion is an electronic component with digital and analogue inputs and outputs and can only be used in combination with an X-AIRCONTROL zone module. Each zone module can be connected to one module for zone expansion. The module for zone expansion is used for signalling to additional heating or cooling valve actuators or electric air heaters that have a 0-10 V signal input. The supply voltage for the heating and cooling valves and for electric air heaters must be provided separately. The following cooling valve, heating valve or electric air heater functions can be selected with the selector switch on the zone expansion module:

Switch set to address 0: 
Aou1 and Aou2 = heating (simultaneously)
Switch set to address 1:
Aou1 and Aou2 = cooling (simultaneously)
Switch set to address 2:
Aou1 = heating; Aou2 = cooling 
Switch set to address 3:
Aou1 and Aou2 = changeover (simultaneously) 
Switch set to address 4:
Aou1 = electric air heater; Aou2 = no function 
Switch set to address 5:
Aou1 and Aou2 = electric air heater (simultaneously) 


Temperature control

The room or extract air temperature is measured on the zone module and continuously compared to the setpoint value. In case of any deviation, the system controls airflows and/or water flows in such a way that the required room temperature is achieved (again). The zone expansion module allows for signalling to additional cooling and heating valve actuators (i.e. cooling and heating actuators in addition to those connected to the zone module) or an electric air heater to control the room temperature. Signalling to the additional actuators is provided via two analogue 0-10V outputs on the zone expansion module.
 If an electric air heater is used, a supply air temperature sensor has to be installed in the duct to ensure that the maximum supply air temperature is not exceeded. The electric air heater must have a modulating phase angle control function (0-10V=0-100%), safety devices (temperature monitor, thermal cut-out) and a volume flow rate monitoring function. Alarms emitted by a safety device can be captured and forwarded with a digital input on the zone module.

X-AIRCONTROL expansion module for the signalling to and monitoring of electric air heaters with a 0-10 V DC interface, or for the signalling to valve actuators with a 0-10 V DC interface. The expansion module has analogue and digital inputs and outputs and can only be used together with an X-AIRCONTROL zone module.

The zone expansion module is connected to the X-AIRCONTROL zone module by means of a bus (RS485 Modbus RTU) with automatic recognition function (plug and play).
