Energy saving tips

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 20).
■ Heat your rooms with the standard
room temperature during the day and
the reduced temperature at night. Set
the time program for this. Select the
time phases according to your needs,
e.g. differently at the weekend to the
weekdays (not for underfloor heating
systems, see page 9).

■ For room heating or room cooling,
select the heating program that meets
your current requirements:
– For short absences (a couple of
hours, e.g. shopping trips), select
"Economy mode" (not for under-
E
floor heating systems, see
page 9).
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 27).
As long as the holiday program is
activated, the room temperature is
reduced and DHW heating is OFF.
– In summer, if you do not want to heat
any rooms but do need DHW, select
the operating program "Only
DHW" (see page 30).
– If you don't want to heat the rooms
and don't require DHW for an exten-
ded period, select the operating pro-
gram "Standby mode" (see
page 16).
■ Do not set the DHW cylinder temper-
ature B too high (see page 29).
■ Only activate the DHW circulation
pump for when DHW is drawn off reg-
ularly. Set the time program for this
(see page 34).
