* This setting does not apply to the QAW740 room unit; in that case, the setting is made directly on the room
unit
The activated timer can be stopped by changing the room operating mode (e.g. via the
room operating mode selector).
10.4.7 Room control combination
The heating circuit of the RMK770 can be combined with a heating circuit of some other
controller. This combination of 2 room control systems is required, for example, when 1
heating circuit is used for the underfloor heating system and 1 for the radiators. Another
example is the combination of ventilation and heating in a room (e.g. in a hall).
If only the time program shall be jointly used, this can be done without a room control
combination. In that case, the time switch of the heating circuit is to be operated as the
master or slave. For more detailed information, refer to section 5.1 "Time switch".
In the event of a power failure, the operating mode of the slave is on Comfort
master sends another signal via bus.
For more detailed information about ventilation, refer to the Basic Documentation on the
RMU7... (P3140).

Communication is described in chapter 13 "Communication".
Problem:
The basic load is covered by a heating circuit with weather-compensated control and
the load-dependent part by a second heating circuit with or without room influence. The
2 heating circuits shall operate in parallel and be controlled by a common switching
program or a room operating mode selector.
