persons with reduced physical, sensory or mental capa-
bilities or a lack of experience and know-how, provided
that they are supervised or they have been instructed on
how to use the appliance safely and have understood
the resulting risks. Children must never play with the
appliance. Children must never clean the appliance or
perform user maintenance unless they are supervised.
Note
Do not change any system-specific settings at the control
unit. Your contractor has set the control unit to match
the local conditions for your building and your individual
requirements. The system-specific parameters are pro-
tected by a code to prevent unintentional modifications.
The parameters that serve to adapt the appliance to your
personal requirements are not protected by a code.

The CE designation shows that the appliance meets all essential
requirements according to the:
- Electromagnetic Compatibility Directive
- Low Voltage Directive

3. appliance description
The appliance is a heating heat pump suitable for operation as a
brine/water heat pump. The heat pump extracts energy from the
heat source medium at a low temperature level. This extracted
energy is then transferred to the heating water at a higher level,
augmented by the electric energy drawn by the compressor. The
heating water is heated to a flow temperature of up to 60 °C,
depending on the heat source temperature.
A heating circuit pump and a multi function assembly (MFG) with
safety assembly and 3-way diverter valve have been integrated
in the appliance for directing the flow either to the heating circuit
or the DHW circuit. To heat the DHW, the heating water that has
been heated by the heat pump is directed through an indirect coil
in the DHW cylinder, where it transfers its energy to the DHW.
The appliance is equipped with an electric emergency/booster
heater (DHC). If the dual mode point can no longer be maintained
in mono mode operation, the electric emergency/booster heater
is activated to safeguard heating operation and the provision of
high DHW temperatures. In mono energetic operation the electric
emergency/booster heater is then activated as a booster heater.
The appliance is regulated by an integral, weather-compensated
return temperature controller (WPM3i heat pump manager).
The WPM3i also regulates the DHW heating to the required tem-
perature. If either the high pressure sensor or the hot gas limiter
of the heat pump responds during DHW heating, then DHW heating
will automatically be completed by an integral electric emergency/
booster heater, subject to the DHW learning function being disa-
bled. If the DHW learning function is enabled, DHW heating will
cease and the set DHW value is overwritten with the actual DHW
temperature achieved.
The WPM3i also controls the integral electric emergency/booster
heater. No further heat generator can be switched.
3.1 Special features of the Wpc...cool
An additional heat exchanger and 3-way diverter valve for chang-
ing over between heating and cooling are integrated into the
WPC...cool.
To cool the living space, the brine is pumped though the additional
heat exchanger, where heat is extracted from the heating water
to be released into the cooler zones underground.
The compressor does not run during cooling.
