20.1.3 Interplay with room unit QAW70

In combination with the QAW70, the following functions can be performed, or the
room unit can act on the controller as follows:
Overriding the heating circuit's operating mode
Changing room temperature setpoints
Changing the d.h.w. temperature setpoint
Readjustment of room temperature
Input of time of day
Overriding the heating program
Display of the actual values acquired by the controller
For this purpose, the QAW70 has the following operating elements:
Operating mode button
Economy button (also termed presence button)
Knob for readjusting the room temperature
Buttons for selecting the operating lines
Buttons for readjusting values
From the QAW70, the heating circuit's operating mode can be overridden. This is
accomplished via the operating mode selector and the economy button.
To enable the room unit to act on the controller, the latter must satisfy the following
operating conditions:
Heating circuit operating mode AUTO
No holiday period active, no manual control
The operating mode selector of the QAW70 acts on the controller as follows:
Operating mode Operating mode of heating circuit controller
of QAW70
Continuously NORMAL
heating, depending on the economy button
Protection mode
With the knob of the QAW70, the room temperature setpoint for NORMAL heating
can be readjusted by ±3 °C.
The QAW70 does not affect the adjustment of the room temperature setpoint on
the controller's operating line 1.
If the controller with a connected QAW70 is isolated from the mains network and
then reconnected, the following parameters on the QAW70 will be overwritten with
the settings made on the controller:
Time of day and weekday
Complete heating program
Room temperature setpoint for NORMAL heating
Room temperature setpoint for REDUCED heating
D.h.w. temperature setpoint
Hence, the controller is always the data master.
