minology" (see page 44).

Tips on saving energy

Utilise the setting options for the control
unit and remote control (if installed):
■ Never overheat your rooms. Every
degree by which the room temperature
is reduced saves up to 6 % on heating
costs.
Never set your room temperature
higher than 20 °C (see page 18).
■ Never set the DHW temperature too
high (see page 25).
Introductory information
(cont.)
■ Only activate the DHW circulation
pump for times when DHW is drawn
off. Set the time program for this (see
page 27).
■ Select the heating program that meets
your current requirements:
– For short absences (e.g. shopping
trips), select "Economy mode"
(see page 23).
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 23).
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 heating program "Only
DHW" (see page 25).
