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.

3. Appliance description
3.1 Properties
The appliance is an air source heat pump designed for
use as a heating heat pump. The appliance extracts heat
from the outdoor air at a low temperature level and trans-
fers it to the heating water at a higher temperature level.
The heating water can be heated up to a flow temperature of 60 °C.
The appliance is equipped with an electric emergency/booster
heater (DHC). If the dual mode point is undershot in mono mode
operation, the electric emergency/booster heater is activated to
safeguard heating operation and the provision of high DHW tem-
peratures. In such a case in mono energetic operation, the electric
emergency/booster heater is activated as a booster heater.
This appliance has further operational characteristics:
- Suitable for underfloor and radiator heating.
- Preferred for low temperature heating systems.
- Extracts heat from the outdoor air even at outside tempera-
tures of -20 °C.
- Corrosion-protected, external casing made from hot-dipped
galvanised sheet steel plus stove-enamelled finish.
- Comprises all components and safety equipment required for
operation.
- Filled with non-combustible safety refrigerant.
Note
For centralised control of the heating system, you would
need the WPM heat pump manager.
