The heating settings for an RMH slave controller programmed with basic type 0-2
are carried out under:
...> Commissioning > Communication > Room 1
Geogr zone (apart): 3
...> Commissioning > Extra configuration > Heating circuit 1 > Functions
Room control combination: Ext. setpoint (slave, internal setpoint
...> Commissioning > Extra configuration > Heating circuit 1 > Optimizations/Influences

The heating setpoints

Both controllers then operate with the same heating setpoint. If a heating controller
setpoint needs to be adjusted, it must be changed in the ventilation controller
(master).
