3 Operation and maintenance
NOTE
The unit is operated via the control panel
of the heating and heat pump controller
(  operating manual of the heating and heat
pump controller).
3.1 Energy and environmentally-
conscious operation
The generally accepted requirements for an energy-
conscious and environmentally-conscious operation of
a heating system also apply to use of a heat pump.
The most important measures include:
● No unnecessarily high flow temperature
● No unnecessarily high domestic hot water
temperature (note and follow local regulations)
● Do not open windows with just a gap or tilt open
(continuous ventilation); instead, open wide for a
short time (shock ventilation).
● Always ensure that the controller settings are
correct
3.2 Maintenance
Wipe down the outside of the unit only using a damp
cloth or cloth with mild cleaning agent (washing-up
liquid, neutral cleaning agent). Do not use any harsh,
abrasive, acid or chlorine-based cleaning products
