20.1 Interplay with room units

20.1.1 General
The room temperature acquired by a room unit is fed to controller terminal A6. If
the room temperature signal delivered by the room unit shall not be included in the
control functions, the respective source must be selected (operating line 65). In
that case, the other room unit functions are maintained.
The controller detects the connection of an inadmissible room unit and identifies
it as an error for display on operating line 50 (error code 62)
Errors the room unit detects in itself are displayed by the controller on operating
line 50 (error code 61)

20.1.2 Interplay with room unit QAA50.110/101

The QAA50.110/101 can act on the controller as follows:
Overriding the heating circuit's operating mode
Readjustment of room temperature
For that purpose, the QAA50.110/101 has 3 operating elements:
Operating mode selector
Economy button (also termed presence button)
Knob for room temperature readjustments
On the QAA50.110/101, the following settings are required:
For heating circuit 1, address 1 (factory setting)
For heating circuit 2, address 2
From the QAA50.110/101, the operating mode of the heating circuit can be over-
ridden. This is accomplished via the operating mode selector and the economy but-
ton.
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 QAA50.110/101 acts on the controller as fol-
lows:
Operating mode Operating mode of heating circuit controller
of QAA50.110/101
Continuously NORMAL
heating, depending on the economy button
Protection mode
With the knob of the QAA50.110/101, the room temperature setpoint for NORMAL
heating can be readjusted by ±3 °C.
The QAA50.110/101 does not affect adjustment of the room temperature setpoint
on the controller's operating line 1.
