1.4 Units of measurement
Note
All measurements are given in mm unless stated oth-
erwise.
1.5 Standardised output data
Explanations to determine and interpret the specified standardised
output data.
1.5.1 Standard: EN 14511
The output data specifically mentioned in text, diagrams and
technical datasheets has been calculated according to the test
conditions of the standard shown in the heading of this section.
Generally, these standardised test conditions will not fully meet
the conditions found at the installation site of the system user.
Depending on the chosen test method and the extent to which
this method deviates from the conditions defined in the norm
shown in the heading of this section, any deviations can have a
considerable impact.
Further 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.
A confirmation of the specified output data can only be obtained
if the test conducted for this purpose is also performed in ac-
cordance with the conditions defined in the norm shown in the
heading of this section.
2. Safety
Only qualified contractors should carry out installation, commis-
sioning, maintenance and repair of the appliance.
Contractors are responsible for adherence to all currently applica-
ble regulations during installation and commissioning.
2.1 Intended use
The appliance is intended to heat buildings and domestic hot water
(DHW). The appliance is designed for extracting energy from the
air and utilising this energy in water-based heating systems within
the stated operating temperature range.
This appliance is designed for domestic use. It can be safely oper-
ated by untrained personnel. The appliance can also be used in a
non-domestic environment, e.g. in a small business, 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 is also part of the correct use
of this appliance. Any changes or modifications to this appliance
void all warranty rights.
2.2 General safety instructions
Observe the following safety instructions and regulations.
- The electrical installation and installation of the heating cir-
cuit must only be carried out by a recognised, qualified con-
tractor or by our customer service engineers
- Contractors are responsible for adherence to all currently ap-
plicable regulations during installation and commissioning.
- Operate the appliance only when fully installed and with all
safety equipment fitted
- Protect the appliance from dust and dirt ingress during
building work

WARNING Injury
The appliance may be used by children aged 8 and up
and persons with reduced physical, sensory or mental
capabilities or a lack of experience provided that they
are supervised or they have been instructed on how to
use the appliance safely and have understood the result-
ing risks. Children must never play with the appliance.
Children must never clean the appliance or perform user
maintenance unless they are supervised.
2.3 Test symbols
See type plate on the appliance.
3. Appliance description
The appliance is an air source heat pump that operates as a heating
heat pump. Heat is extracted from the outdoor air at a low temperature
level, and is then transferred to the heating water at a higher level.
The heating water can be heated up to a flow temperature of 75 °C.
The appliance is equipped with an electric booster heater (DHC).
The electric booster heater is activated if the dual mode point is
not achieved in mono mode operation in order to ensure the heat-
ing operation and the availability of high DHW temperatures. In
such cases the electric booster heater is activated as an additional
heat source in mono energetic operation.
