vised or have been instructed in safe use of the device and un-
derstand the associated potential dangers.
Children must not play with the device. Cleaning and user
maintenance must not be carried out by children without su-
pervision.
1.5 Energy-efficient use of the heat
pump
By operating this heat pump, you are helping to protect the en-
vironment. A prerequisite for energy-efficient operation is the
correct design of the heat source system and heating system.
To maintain heat pump efficiency, it is particularly important to
keep the temperature difference between the heating water
and heat source to a minimum. For this reason, it is advisable to
design the heat source and heating system very carefully. A
temperature difference that is higher by 1 Kelvin (1°C) in-
creases the power consumption by around 2.5%. When de-
signing the heating system, it should be borne in mind that spe-
cial consumers such as domestic hot water preparation should
also be taken into consideration and dimensioned for low tem-
peratures. Underfloor heating systems (panel heating) are
optimally suited for heat pump use on account of the low flow
temperatures (30 °C to 40 °C).
It is important to ensure that the heat exchangers are not con-
taminated during operation, as this increases the temperature
difference, which in turn reduces the coefficient of perfor-
mance (COP).
When set correctly, the heat pump manager is also an essential
factor in the energy-efficient use of the heat pump. Further in-
formation can be found in the heat pump manager operating
instructions.

2 Intended use of the heat
pump
2.1 Area of application
The air-to-water heat pump is to be used exclusively for the
heating and cooling of heating water. It can be used in new or
existing heating systems.
The heat pump is designed exclusively for outdoor installation.
The instructions in the chapter "Installation" must be observed.
The circulating pump(s) must be controlled using the heat
pump manager.
If pump functions relevant to the overall function or to safety
are not supported, e.g. due to integration of the heat pump into
a building management system, this results in the warranty
being void and can lead to damage to the heat pump.
The circulating pump(s) and the heat pump controller must al-
ways be ready for operation.
The specifications in the technical documents must be fol-
lowed, particularly limit values for the minimum and – if availa-
ble – maximum warm/cold water volume flow.
The heat pump is suitable for mono energy and bivalent opera-
tion in outside air temperatures to -22°C.
Proper defrosting of the evaporator is guaranteed by maintain-
ing a heating water return temperature of more than 20 °C dur-
ing continuous operation. The maximum water outlet tempera-
ture must not exceed 65°C and must be secured on the system
side so that, if the temperature is exceeded, all additional heat
sources are switched off safely.
The heat pump is not designed for the increased heat con-
sumption required when a building is being dried out. For this
reason, the additional heat consumption should be met using
special devices provided by the customer. For drying out a
building in autumn or winter, it is advisable to install a suitable
2nd heat generator (e.g. an electric heating element available as
an accessory).
In cooling operation, the heat pump is suitable for air tempera-
tures ranging from +15°C to +45°C.
It can be used for silent and dynamic cooling. The minimum
cooling water outlet temperature is +12°C.
CAUTION!
Use of a 4-way valve on the heating water side can cause
damage to the device.
A 4-way valve must not be used on the heating water side
2.2 Operating principle
Heating with the heat source air
Surrounding air is drawn in by the fan and fed through the evap-
orator (heat exchanger). The evaporator cools the air, i.e. ex-
tracts heat from it. This extracted heat is then transferred to the
working medium (refrigerant) in the evaporator.
The heat is "pumped" to a higher temperature level by increas-
ing its pressure with the aid of the electrically driven compres-
sors. It is then transferred to the heating water via the liquefier
(heat exchanger).
Electrical energy is used to raise the temperature level of the
heat from the environment. Since the energy extracted from
the air is transferred to the heating water, this type of device is
referred to as an air-to-water heat pump.
The air-to-water heat pump consists of the main components
evaporator, fan and expansion valve, as well as the low-noise
compressors, the liquefier and the electrical control system.
At low ambient temperatures, humidity accumulates on the
evaporator in the form of frost, reducing the transfer of heat.
Uneven accumulation during this process does not indicate a
fault. The evaporator is defrosted automatically by the heat
pump as required. Under certain atmospheric conditions,
steam may be emitted from the air outlet.
Cooling
The functions of the evaporator and the liquefier are reversed in
the "Cooling" operating mode.
The heating water transfers its heat to the refrigerant via the liq-
uefier, which is now functioning as an evaporator. The refriger-
ant is brought to a higher temperature level using the compres-
sor. Heat is transferred to the surrounding air via the liquefier
(which, in heating operation, functions as an evaporator).
