c . Cascade Room Temperature Control
Only possible with the humidity-temp. sensor KWL-FTF accessory.
Connect the analogue output A2 (temp. signal) of the KWL-FTF to the analogue input AI2 of the ventilation unit (see
wiring diagram).
The cascade control of the room and supply air temperature is used to maintain a constant, adjustable room tempe-
rature. The supply air temperature setpoint is set by the room temperature controller according to the deviation of the
ambient temperature from the room temperature setpoint.
The room temperature setpoint is displayed in the "temperature" menu (log in as User or Administrator):
