17.1.3.1. Overriding the operating mode
From the QAW70, the operating mode of the RVL470 can be overridden. This is ac-
complished with the operating mode button and the economy button.
To enable the room unit to act on the RVL470, the following operational conditions must
be satisfied on the controller:
•
AUTO mode
•
No holiday period active, no manual operation
The effect of the QAW70's operating mode button on the RVL470 is as follows:
Operating mode

17.1.3.2. Setting knob for room temperature readjustments
With the setting knob of the QAW70, the room temperature setpoint of NORMAL heat-
ing can be readjusted by ±3 °C.
The setting of the room temperature setpoint on the controller's operating line 1 will not
be affected by the QAW70.
17.1.3.3. Effect of the individual QAW70 operating lines on the RVL470
If 1 (slave with no remote adjustment) is entered on operating line 178 (clock mode) of
the RVL470, the time of day on the QAW70 cannot be changed.
