This setting does not apply to the QAW740 room unit; in that case, the setting is to be
made directly on the room unit.
The activated timer can be stopped by changing the room operating mode (e.g. via the
room operation selector).
9.3.5 Room operating mode outputs
Function block outputs "Operating mode R1" and "Operating mode R2" enable the
resulting room operating mode of a heating circuit to be output via one or 2 relays. This
is always possible, even if heating circuit control is not used.
Forwarding the resulting room operating mode from the Qx relay outputs of the
RMH760B to a Synco™200 controller:
