1Safetynotes
1.1 Symbols and markings
Particularly important information in these instructions is
marked with CAUTION! and NOTE.
CAUTION!
!
!
Immediate danger to life or danger of severe personal injury or
significant damage to property.
NOTE
º
ºººº
Risk of damage to property or minor personal injury or
important information with no further risk of personal injury
or damage to property.
1.2 Intended use
This device is only intended for use as specified by the manu-
facturer. Any other use beyond that intended by the manufac-
turer is prohibited. This requires the user to abide by the rele-
vant project planning documents. Please refrain from
tampering with or altering the device.
1.3 Legal regulations and directives
This heat pump is designed for use in a domestic environment
according to Article 1, Paragraph 2 k) of EU directive 2006/42/
EC (machinery directive) and is thus subject to the require-
ments of EU directive 2014/35/EU (low-voltage directive). It is
thus also intended for use by non-professionals for heating
shops, offices and other similar working environments, in agri-
cultural establishments and in hotels, guest houses and similar
/ other residential buildings.
The construction and design of the heat pump complies with all
relevant EU directives, DIN/VDE regulations (see CE declaration
of conformity).
When connecting the heat pump to the power supply, the rele-
vant VDE, EN and IEC standards are to be adhered to. Any fur-
ther connection requirements stipulated by the network opera-
tor must also be observed.
When connecting the heating system, all applicable regulations
must also be adhered to.
This unit can be used by children aged 8 and over and by per-
sons with limited physical, sensory or mental aptitude or lack of
experience and/or knowledge, providing they are supervised or
have been instructed in the safe use of the unit and understand
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.
CAUTION!
!
!
When operating or maintaining a heat pump, the legal
requirements of the country where the heat pump is operated
apply. Depending on the refrigerant quantity, the heat pump
must be inspected for leaks at regular intervals by a certified
technician, and these inspections must be recorded.
More information can be found in the accompanying log book.
1.4 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.
It is particularly important for the efficiency of a heat pump to
keep the temperature difference between heating water and
heat source as small as possible. For this reason, it is advisable
to design the heat source and heating system very carefully. A
temperature difference of approx. one Kelvin (one °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 e.g. domestic hot water preparation
should also be taken into consideration and dimensioned for
low temperatures. 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 because this increases the temper-
ature difference, in turn reducing the COP.
Correct adjustment of the heat pump manager is also impor-
tant for energy-efficient use of the heat pump. Further informa-
tion can be found in the operating instructions of the heat
pump manager.

2 Purpose of the heat pump
2.1 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
already-existing heating systems.
The heat pump is suitable for mono-energy and bivalent opera-
tion down to an external temperature of -22 °C.
Proper defrosting of the evaporator is guaranteed by maintain-
ing a heating water return temperature of more than 22 °C dur-
ing continuous operation.
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 build-
ings in autumn or winter, we recommend installing a suitable
2nd heat generator (e.g. electric heating element available as an
accessory).
In cooling operation, the heat pump is suitable for air tempera-
tures ranging from +10 °C to + 45 °C.
It can be used for silent and dynamic cooling. The minimum
water temperature is +7 °C.
NOTE
ººººº
The device is not suitable for operation with a frequency
converter.
2.2 Operating principle
Heating
Surrounding air is drawn in by the fan and fed through the evap-
orator (heat exchanger). The evaporator cools the air, i.e. it ex-
tracts heat from it. This extracted heat is then transferred to the
working medium (refrigerant) in the evaporator.
The heat is brought to a higher temperature level by increasing
its pressure with the aid of the electrically driven compressor. It
is then transferred to the heating water via the liquefier (heat
exchanger).
Electrical energy is used to raise the temperature of the heat in
the environment to a higher level. As the energy extracted from
the air is transferred to the heating water, this type of device is
called an air-to-water heat pump.
The air-to-water heat pump consists of the main components:
evaporator, ventilator and expansion valve, as well as the low-
noise compressors, the liquefier and the electrical control sys-
tem.
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. Steam may be emitted from the air outlet de-
pending on the atmospheric conditions.
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).
