Connect room group components
The following room group components are assigned the respective inputs or
outputs:
• Mixing valve
• Flow sensor
• Return sensor
• Room group pump
The components can be connected for room groups 1 and 2.
On the room group components, the respective input and output
functions must be set to "Via RF", enabling an input or output of a
heating circuit controller or multi-controller to be assigned to them.
Connect output for the mixing valve
Inform the central apartment unit that you want to assign the output of a multi-
controller to a room group for the control of a mixing valve:
Main menu > Commissioning > RF connections > Room groups
> Room group X > Mixing valve > Connect device:
Mixing valves can only be connected via an RRV934 multi-controller.
For control of the mixing valve, a universal output Ux (DC 0..10 V) or
the 3-position output (Q4/Q5) of the multi-controller can be used.
Mixing valve, flow and return sensor of the same room group must be
connected to the same multi-controller.
