tank are protected against frost. Wintertime/

Energy saving tips
Use the adjustment options offered by your boiler control
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 25).
The room temperature is reduced for as long as
economy mode is active.
– If you are going away, set the “Holiday program”
(see page 26).
The operating program for central heating is
automatically set to “Standby mode” while the holiday
program is active.
– If, for an extended period, you neither want to heat
the interior nor do you require DHW, select the
“Standby mode” operating program for the relevant
heating circuits and for DHW.
– See page 23 for the relevant heating circuits
– See page 28 for DHW heating
Never set the DHW tank temperature excessively
high (see page 28).
Contact your heating contractor for additional energy
saving functions offered by your boiler control unit.
For general recommendations on energy savings, see
page 51.
Your boiler’s control unit is set at the factory.
The heating circuits are set to the “Heating” operating

Your heating contractor can make further settings for
you during commissioning. You can change any settings
at any time to suit your individual requirements (see
from page 18).
