* Outside temperature relay:
Only heating circuits 2 and 3 have their own outside temperature. Heating circuit 1 shares the outside tem-
perature with other function blocks in the controller. The outside temperature relay for the outside tempera-
ture of heating circuit 1 is to be configured under
Miscellaneous > Outputs.
9.2.1 3-position or modulating mixing valve
Control of the mixing valve can be accomplished either with a 3-position or DC 0…10 V
actuator. The type of actuator is to be selected via “Extra configuration“.
The output is to be activated via “Extra configuration“:
Main menu > Commissioning > Extra configuration > Heating circuit 1 (or 2 or 3) > Outputs >

9.2.2 Pump control
The heating circuit pump offers the same choices as all the other pumps. An individ-
ual pump can also be monitored; optionally, a twin pump can be used as a heating
circuit pump. For that, the relevant output must be configured.
For more detailed information, refer to section
5.8 “Pump control and twin pumps”.

9.3 Operating modes in the heating circuit
9.3.1 Room operating modes
The room operating mode determines the state of a heated room. A differentiation is to
be made between preselected room operating mode and the state of the room operat-
ing mode. Room operating mode
is only available as a preselection.
The user can preselect the following operating modes for space heating:
