Energy saving tips
Use the adjustment options offered by your boiler con-
trol unit:
For central heating, select the operating program
■
that meets your current requirements:
–
For short periods of absence (a few hours, such as
shopping trips), select "Economy mode" (see
page 30).
The room temperature is reduced for as long as
economy mode is active.
–
If you are going away, set the "Holiday program"
(see page 31).
The operating program for central heating is auto-
matically set to "Standby mode" while the holiday
program is active.
–
If you do not want to heat the rooms and you do
not require DHW for an extended period, set the
"Standby mode" operating program for the rele-
vant heating circuits and for DHW.
See page 29 for the relevant heating circuits
–
–
See page 35 for DHW heating
■
Never set the DHW cylinder temperature excessively
high (see page 33).
Contact your heating contractor for additional energy
saving functions offered by your boiler control unit.
