Selecting a heating/cooling circuit
The heating/cooling of all rooms can be distributed
amongst several heating/cooling circuits, e.g. a heat-
ing/cooling circuit for your apartment, and a heating/
cooling circuit for your office.
In the menu bar, the following designations are used at
the factory: "Heating/cooling circuit 1", "Heating/
cooling circuit 2", etc. You can alter these designa-
tions: See chapter "Naming heating/cooling circuits".
If your system has several heating/cooling circuits, in
■
"Indoor environment" in the default display, first
select the heating/cooling circuit for all room heating/
room cooling settings that you want to change.
■ If there is only one heating/cooling circuit, this selec-
tion option is not available.
Setting the room temperature for a heating/cooling circuit
The standard room temperature is the temperature at
which you feel comfortable. Your home is always
heated or cooled to this temperature when a time
phase with the temperature level "Standard" is active
in the time program.
