9.10.3 Room control combination

The heating circuit of the RMH760B can be combined with a heating circuit of some
other controller. The combination of 2 room control systems is required when one
heating circuit is used for the underfloor heating system and one for the radiators, for
example. Another example is the combination of ventilation and heating in a room (e.g.
in a hall).
If only the time program shall be commonly 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 a master or slave. For more detailed information, refer to section 5.1 "Time switch".
In the event of a power failure, the slave's operating mode is Comfort
master sends another signal via bus
For more detailed information about ventilation, refer to the Basic Documentation on
the RMU7...B (P3150).

Communication is described in chapter 14 "Communication".
Requirement:
The basic load is covered by a weather-compensated heating circuit and the load-
dependent part by a second heating circuit with or without room influence. The 2 heat-
ing circuits shall operate parallel and be controlled by a common switching program or
room operation selector.
Solution:
Using the extra function "Room control combination", one of the 2 heating circuits as
the master can predefine the operating mode for the second heating circuit, which is
configured as the slave.
If required, the setpoints can also be adopted by the master. This is accomplished with
the configuration "Slave external setpoint".
