Dew point
Radiator/floor cooling is disabled by closing the contact of an external dew
point monitor, or enabled when the contact opens.
The dew point monitor closes the room group mixing valve if a room group
precontroller is installed. If only a room group pump is installed, the dew point
monitor shuts off the room group pump. If there is neither a precontroller nor a
room group pump, the dew point monitor closes the room valves. The dew
point monitor always acts on both room groups.
Specify if an external dew point monitor is used and from where the central
apartment unit receives its status.

mode selected for the period of absence.
