Cooling, auto
Setting option: on/off
Start passive cooling
Setting alternative: 10 – 500 DM

Degree minutes are a measurement of the current heat-
ing/cooling demand in the house and determine when the
compressor or additional heat will start/stop.
MENU 7.5.3 - FORCED CONTROL
Here you can force control the various components in the
