The commissioning and matching of the control unit to
local conditions and building characteristics, as well as
instructing the user in the operation of the system,
must be carried out by your heating contractor.
As the user of new combustion equipment, you may be
obliged to notify your local flue gas inspector of the
installation [check local regulations]. Your local flue gas
inspector (where applicable) will also provide you with
information on additional activities concerning your
combustion equipment (such as regular testing, clean-
ing, etc.).

than 20 °C.

Heat your home to the standard room temperature
during the day and the reduced temperature at night.
Set the time program for this.
■

If you do not require central heating, select one of
the following operating programs:
–
"DHW only"
:
If you require no heating for your home in summer,
but you need hot water.
–
"Standby mode"
:
If you don't need to heat your home and don't need
hot water for long periods.
