Dew point limit
When cooling, the minimum flow temperature is limited. The
limit (dew point) is calculated by the heat pump controller from
the following variables:
- Current room temperature
- Current relative humidity in the room
If no room temperature value is available, the current outside
temperature is used. If no relative humidity value is available,
the dew point temperature is calculated using a relative hu-
midity figure of 60 % as a default value.
Room temperature and room humidity are captured by the
room programming units or the WP-RT Touch.
Property damage
!
Improper settings on the cooling curve can cause
damage to the system (due to condensation).
f Make changes to the cooling curve only by agree-
ment with your contractor.
