Operation

 

 

Control during At outside temperatures below the frost-protection limit (see holidays 5.2.3 "System Parameters" menu, pg. 72) the heating circuits are

controlled as follows:

Without wall devices: Based on a lowered room temperature specification of 3 °C.

With wall devices: Based on the room frost-protection limit of the respective heating circuit of 10 °C (see "Direct Heating Circuit" or "Mixed Heating Circuit 1", "Mixed heating circuit 2" menu, parameter 08 = room frost-protection limit).

Cancellation An active holiday program can be cancelled in case of early return.
