P 21 Room, supply or extract air temperature regulation
The room, supply air or extract air temperature regulator compares the air temperature
measured at the temperature sensors with the reference temperature set on the control
unit In the case of heating, a difference between the set-point and actual temperature
causes the controller to increase or reduce the heat output.
P 21 Supply air temperature control
With supply air temperature control, the external heat
source is not taken into account.
Fixed supply air temperature. No other adjustability.
P 21 Extract air temperature control
With extract air regulation, any external heat source in the
room will be taken into account and compensated for by a
correction to the supply air. Fixed extract air temperature.
No other adjustability.
P 21 Room temperature control
With room temperature control, any external heat source
in the room will be taken into account and compensated
for by a correction to the supply air temperature. The room
temperature sensor is in the control unit.
The following parameters are for all types of control:
