Functional description

The main PCB, which is required for each decentralised ventilation unit, controls all functions that are necessary for operation, e.g. providing the control signal for fans and actuators.

If a master PCB is added, the existing controller becomes a master controller; at least one master controller is required in each room.

Additional inputs and interfaces allow for the connection of components that are required for room control.

The RTC interface on the master PCB allows for adding a timer; the LON FTT 10, BacNet MS/TP or Modbus RTU interface allows for establishing a connection to the central BMS (by others).

Operating temperature	0 – 50 °C
Relative humidity	<90% no condensation
Air pressure	> 700 hPa
Storage temperature	–20 to 70 °C
Power consumption (depending on equipment)	4 – 10 W

INSTALLATION DETAILS

Installation and commissioning

Control equipment and expansion modules are factory mounted and wired either in the ventilation unit or in a separate box
The control panel should be mounted approx. 1.5 m above the floor. Select an installation location where the control equipment is not affected by disturbances (e.g. solar gain, draughts)
The control equipment is factory configured, but the configuration can be changed on site (using configuration software)
We recommend adjusting the flow temperature based on the outdoor temperature in winter and based on the dew point in summer
An on-site service check by our Technical Service is recommended
