Your heating contractor may have adjus-

Enabling an electric booster heater
If the heat pump on its own cannot ach-
ieve the selected set room temperature,
an instantaneous heating water heater (if
installed) can be started automatically to
boost central heating.
Constant operation of an instantaneous
heating water heater results in high elec-
tricity consumption. You can block the
electric booster heater individually.

Changing the heating curve

The heating characteristics of your heat
pump are affected by the slope and level
of the selected heating curve. Further
information about the heating curve can
be found in chapter "Terminology" (see
page 60).
Factory settings:
■ "Slope": 0.6
■ "Level": 0
