30.3.2 Overriding the operating mode
From the QAW70, the controller’s operating mode can be overridden. This is made with
the operating mode button and the economy button.
To enable the room unit to act on the controller, the latter must be in automatic mode.
The actions of the QAW's operating mode button on the controller are as follows:
Operating mode QAW70 Operating mode RVD230
Automatic operation; temporary overriding with the
economy button of the QAW70 possible
Economy button off (lit): Nominal room temperature
Economy button on (not lit): Reduced room temperature
Standby
If the room unit overrides the controller’s operating mode, the operating mode button
on the controller flashes.
30.3.3 Knob for readjusting the room temperature
Using the knob of the QAW70, the nominal room temperature setpoint can be read-
justed by a maximum of ±3 °C.
The adjustment of the room temperature setpoint on the RVD230 will not be affected by
the QAW70.
