Utilise the setting options offered by the
heat pump control unit A and by the
remote control (if installed):
■ Never overheat your rooms. Every
degree by which the room temperature
is reduced saves up to 6% on heating
costs.
Set your room temperature no higher
than 20 ºC (see page 18).
■ Never set the DHW temperature too
high (see page 27).

■ Only activate the DHW circulation
pump for when DHW is drawn off reg-
ularly. Set the time program for this
(see page 31).
■ Select the program that meets your
current requirements:
– For short absences (e.g. shopping
D
trips), select "Economy mode"
(see page 25).
As long as economy mode is activa-
ted, the room temperature is
reduced.
– If you are going away, set the "Hol-
iday program" (see page 25).
As long as the holiday program is
activated, the room temperature is
reduced and DHW heating is OFF.
– In summer, when you don't want to
heat any rooms but do need DHW,
select the operating program "DHW
only" (see page 28).
– If you don't want to heat the rooms
and you don't require DHW for an
extended period, select the operat-
ing program "Standby mode" (see
page 15).
For additional energy saving functions of
the heat pump control unit, please con-
tact your heating contractor.
