electric reHeatinG
dual mode temp dHW
Dual mode temperature of the heat pump for DHW heating.
Below this outside temperature, the electric emergency/booster
heater is switched on for DHW heating, subject to load.
loWer app limit dHW
Lower application limit of the heat pump for DHW heating.
The heat pump is switched off at outside temperatures below the
selected lower DHW application limit.
The electric emergency/booster heater alone provides DHW heat-
ing.
5.4.4 coolinG
The appliance is designed for DHW and central heating. Passive
cooling is possible in conjunction with the WPC cool. In the de-
livered condition, the COOLING parameter is set to OFF. Active
cooling mode is only possible in conjunction with the WPAC 2
cooling module.

Appliance and system damage
You must not enable the COOLING parameter without a
cooling module.

!
Appliance and system damage
Set the COOLING parameter to ACTIVE COOLING.
Note
The COOLING parameter will only be shown if an FEK or
FE7 remote control is connected. Cooling mode is only
possible in summer mode.
the Wpc with the Wpac 2 cools in 2 stages:
Stage 1 (source pump)
Heat is extracted from the heating circuit and is passed to the
heat source system.
Stage 2 (source pump + compressor)
In addition, the refrigerant circuit extracts heat from the heating
circuit and transfers it to the heat source system.
dHW heating
DHW heating always has priority. As long as the actual tempera-
ture has not dropped below the set flow or room temperature, ac-
tive cooling continues even during DHW heating, and any extracted
heat is transferred to the DHW. If there is no cooling demand, DHW
is conventionally heated via the heat source system.
cooling mode with the fe7
The FE7 remote control is not equipped with dew point monitor-
ing. It can therefore only be used in conjunction with fan convec-
tors with condensate drain. The cooling mode parameter must
be set to FAN.
cooling mode with the feK
The FEK remote control is equipped with dew point monitoring,
and can therefore be used with area heating systems (e.g. under-
floor/wall heating systems, etc.). The COOLING parameter must be
set to AREA COOLING. The set flow temperature is compared with
the captured dew point temperature, so the actual temperature
never drops below the dew point. When using fan convectors
with the FEK remote control, set the COOLING parameter to FAN
COOLING.
In the COOLING parameter, you can select the following cooling
modes for the FE7 and the FEK:
- Room temperature
Cooling mode starts when the selected room temperature is
exceeded (output COOLING=230 V).
Cooling mode is stopped when the actual room temperature
drops 2 K below the set temperature. (output COOLING=0 V)
