Depending on the chosen test method and the extent to which
this method differs from the test conditions defined in the first
paragraph of this section, any deviations can be considerable.
Additional factors that have an influence on the test values are the
measuring equipment, the system configuration, the age of the
system and the flow rates.
Confirmation of the specified output data can only be obtained if
the test conducted for this purpose is also performed in accord-
ance with the test conditions defined in the first paragraph of this
section.
2. Safety
2.1 Intended use
The appliance is designed for:
- Heating rooms
- Heating of DHW
- Cooling rooms (only WPE-I HK 230 Premium)
Observe the operating limits listed in chapter "Specification".
The appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in non-do-
mestic environments, e.g. in small businesses, as long as it is
used in the same way.
Any other use beyond that described shall be deemed inappropri-
ate. Observation of these instructions and of instructions for any
accessories used is also part of the correct use of this appliance.
2.2 Safety instructions
- Only recognised, qualified contractors may carry out the
electrical work and installation of the heating circuit.
- The qualified contractor is responsible for adherence to all
applicable regulations during installation and commission-
ing.
- The appliance should only be operated once it is fully in-
stalled and all safety equipment has been fitted.
- Protect the appliance from dust and dirt during building
work.
- Observe the safety concept for operation of the appliance
(see chapter "Preparation / Safety concept").

WARNING Injury
The appliance may be used by children over 8 years of
age and persons with reduced physical, sensory or men-
tal capabilities or a lack of experience and expertise,
provided that they are supervised or they have been
instructed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Cleaning and user maintenance must
not be carried out by children without supervision.
!
WARNING Injury
f f For safety reasons, only operate the appliance with
the casing closed.

3. Appliance description
The appliance is a ground source heat pump suitable for operation
as a heating 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 75 °C,
depending on the heat source temperature.
A heating circulation pump, a multifunction assembly (MFG) with
safety assembly and a 3-way valve are integrated in the appliance
for switching between the heating circuit and 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 (NHZ). To safeguard heating operation and the provision
of high DHW temperatures, the electric emergency/booster heat-
er is activated as an emergency heater if the dual mode point is
undershot in mono mode operation. If the same thing happens in
mono energetic operation, the electric emergency/booster heater
is activated as a booster heater.
The appliance is controlled with an integral, outside tempera-
ture-dependent heating circuit temperature control unit (WPM
heat pump manager).
The WPM also controls the DHW heating to the required tem-
perature. DHW heating will be completed automatically by an
integral electric emergency/booster heater, if either the high
pressure sensor or the hot gas limiter of the heat pump responds
during DHW heating, subject to the WW LEARNING FUNCTION
being deactivated. Also subject to the WW LEARNING FUNCTION
being activated, the DHW heating will terminate and the set DHW
value will be overwritten with the actual DHW temperature that
has been achieved.
The WPM also controls the integral electric emergency/booster
heater. An additional heat generator can also be controlled.

Material losses
Incorrect settings can cause damage to the heat pump or
screed. With ground source heat pumps, the heat source
can also be damaged.

If you want to use the heat-up program, observe
the corresponding chapter in the commissioning in-
structions for the WPM heat pump manager.

Material losses
In cooling mode, condensate can form when the dew
point temperature is undershot.
f f Take suitable measures to prevent the formation of
condensate.
!
Material losses
Condensation caused by the temperature falling below
the dew point can lead to material losses. The appliance
is therefore approved exclusively for area cooling.
