6.1.4 Cooling mode
The heat pump
vamp
air
can be used for room
cooling. That is, by reversing the heat pump cycle,
not warm, but cooled water is fed into the heating
system. This flows through the "heating surfaces"
(underfloor heating, wall heating, ..., do not use radia-
tors, too small transfer surface) and can thus lower
the room temperature.
!
CAUTION
- Risk of condensation on the
heating surfaces, when the dew point
temperature is not reached. In order to
prevent this, the use of room sensors with
integrated humidity sensor (e.g. Art. No.
26610) is strongly recommended.
Requirements for cooling mode with the heat

air
–
The parameter
Room effect
[1]
must be set to the
value
On
.
–
The heat pump switches to cooling mode when
no heat is needed for a heating circuit or DHW
tank, and at least one heating circuit makes a coo-
ling request.
–
Temperature specifications must be fulfilled: see

Cooling release

Yes
releases the cooling function for the respective
heating circuit.
Inside setpoint temperature
2
If the actual room temperature falls below the value
set here, the heating circuit will make a cooling
request.
Ambient switch off temperature
3
If the outside temperature drops below the value set
here, the cooling function switches off.
Release times for cooling operation
For the cooling mode, times can be set within which
cooling is permitted (requirements must be met: rea-
ching the required temperatures, ...).
