The ventilation settings for an RMU master controller programmed with plant type
A03 (ADC001 MU1 HQ) are carried out under:
...> Commissioning > Communication > Room
Geogr zone (ap): 3
...> Commissioning > Settings > Controller 1 > Cascade controller
Control strategy: Alternating
The heating settings for an RMH slave controller programmed with basic type 0-2
are carried out under:
...> Commissioning > Communication > Room 1
Geogr zone (ap): 3
...> Commissioning > Extra configuration > Heating circuit 1 > Functions
Room control comb: Ext setp (Slave internal setpoint)
...> Commissioning > Settings > Heating circuit 1 > Optimizations/influences
Room influence: 0
If the same room is controlled by an RMU ventilation controller and an RMH
heating controller, the RMU ventilation controller in this room control combination
must be set to "Master".

The heating setpoints:
Comfort heating setpoint
Pre-Comfort heating setpoint
Economy heating setpoint
are transmitted by the ventilation controller to the heating controller over the KNX
bus. The existing setpoints in the heating controller are overwritten.
Both controllers operate with the same heating setpoint. If a heating controller
setpoint needs to be adjusted, it must be changed in the ventilation controller
(master).
