Your system is preset at the factory
Note
At temperatures below −20 °C, frost protection of the
heat pump, the DHW cylinder and the heating water
buffer cylinder is only ensured if an instantaneous
heating water heater is installed (on site).
Wintertime/summertime changeover
■ This changeover is automatic.

Tips on saving energy

Use the setting options offered by the heat pump con-
trol unit:
■ Do not overheat your rooms; you can save up to 6 %
on your heating bills for every degree you reduce
your room temperature.
Never set your room temperature higher than 20 °C.
■ For central heating/cooling, select the settings that
meet your current requirements.
■ If you do not want to heat any rooms and require no
hot water for a prolonged period of time, switch off
the system.
Do not set the temperature inside the DHW cylinder
■
too high.
Note
Contact your heating contractor for additional energy
saving functions of the heat pump control unit.
Further recommendations:
■ Correct ventilation/airing
Briefly open windows fully and at the same time
close radiator valves (if no mechanical ventilation
system is installed).
■ Close roller shutters (if installed) at dusk.
■ Set the radiator valves correctly.
■ Never cover radiators or radiator valves.
Controlled use of DHW: A shower uses less energy
■
than a full bath.
