heat pump, the DHW cylinder and the heating water
buffer cylinder is only ensured if an instantaneous

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.
