Introductory information

Commissioning

The commissioning and matching up
of the control unit to local conditions
and the structural characteristics of
the building must be carried out by
your heating contractor. During com-
missioning, or after prolonged time
out of use, it may be necessary to set
the time and date.

Your system is preset at the factory

The control unit is preset at the fac-
tory for standard operation. Your heat-
ing system is therefore ready for use:
& Between 6:00 and 22:00 h the sys-
tem provides central heating with
standard room temperature.
& DHW will be heated between 5:30
and 22:00 h. DHW will be heated to
the set temperature subject to a
DHW cylinder being installed. The
DHW circulation pump is switched
ON (if connected to the control unit).
6
As the user of new combustion equip-
ment, you may be obliged to notify
your local flue gas inspector of the
installation [check local regulations].
Your local flue gas inspector will also
inform you [where appropriate] about
work he may be required to perform
on your combustion equipment (e.g.
regular checks, cleaning).
& Between 22:00 and 06:00 h the
system provides central heating
with the reduced room temperature
(set to 3 °C, frost protection).
& Between 22:00 and 05:30 h the
DHW cylinder temperature will not
be boosted. The DHW circulation
pump is switched OFF (if connected
to the control unit).
& The system automatically changes
over between summer and winter
time.
You may change the factory settings
in accordance with personal require-
ments.
