11.8.2 Control mode for room or extract air temperature
control
When the ventilation controller activates "Room temperature control", room
influence on the heating controller must be switched off. Also, there may be no
thermostatic radiator valves fitted in the room.
Both controllers must have the same geographical zone set.
In the
Comfort and Precomfort modes, the ventilation controller ensures that
the required room temperature is maintained. The heating system controls the
weather-compensated flow temperature. In
Economy mode, the ventilation
controller is normally switched off, and the heating system controls the weather-
compensated flow temperature. When the heating system is on (in winter and
during intermediate seasons), the sustained "Heating" function on the ventilation
controller is deactivated. It is released again only when the heating controller
switches off.

When the ventilation controller activates control function "Room / supply air
temperature cascade control", room influence on the heating controller must be
