Appliance functions
- Fully automatic heating of heating water.
- Suitable for underfloor heating and radiator heating systems;
preferentially for low temperature heating systems, as these
achieve higher performance factors.
- Extraction of energy from outdoor air, even at outside tem-
peratures as low as -20 °C.
- Centralised control of the heating system and safety functions
through the heat pump manager.
- Lower average flow temperature and higher seasonal perfor-
mance factor thanks to intelligent output control.
- Comprises all components and safety equipment required for
operation.
- Compact space requirement due to compact design.
Heat pump manager functions
- System expansion through the FEK and FE 7 remote controls.
- Input of the system and heat pump frost protection limits.
- Automatic pump kick control.
- Reset option.
- Stored fault list with precise fault code indication on the dis-
play, including date and time.
- Fast and precise fault diagnosis via system analyser, including
temperature scanning of heat pumps and system without ad-
ditional equipment.
- Factory settings for time switch programs for all heating and
DHW circuits.
3.1 Energy saving tip
Heat pumps operate with particular economy and environmental
responsibility when run at a maximum flow temperature of 35 °C.
- Low flow temperatures can be achieved by using area
heating systems (e.g. underfloor heating or wall heating
systems).
- For radiator heating systems size radiators to a maximum
flow temperature of 45 °C.
- If the DHW cylinder needs to be heated to 60 °C once a day to
ensure pasteurisation, activate parameter PASTEURISATION.

If you have any questions about pasteurisation, please ask
your contractor.
4. Settings
Operation is divided into three control levels. Control levels 1 and
2 are accessible to users and contractors alike. Control level 3 is
reserved for contractors:
Control level 1 (control flap closed)
This enables the adjustment of operating modes, such as standby
mode, programmed operation, constant day or setback mode etc.
Control level 2 (control flap open)
This enables system parameters, such as room temperatures, DHW
temperatures, heating programs etc. to be adjusted.
Control level 3 (for contractors only)
This level is protected by a code and should only be used by a
qualified contractor. Here, you can determine the specific details
regarding the heat pump and the heating system.
