Commissioning; Your System Is Preset At The Factory - Viessmann VITODENS Operating Instructions Manual

Introductory information

Commissioning

The commissioning and matching of the
control unit to local conditions and build-
ing characteristics, as well as instructing
the user in the operation of the system,
must be carried out by your heating con-
tractor.

Your system is preset at the factory

The control unit is factory-set to "Heat-
ing and DHW".
Your heating system is therefore ready
for use:
Central heating
■ Between 6:00 and 22:00 h, the rooms
are heated with 20 °C "Set room
temp" (standard heating mode).
■ Between 22:00 and 6:00 h, the rooms
are heated with 3 °C "Set reduced
room temp" (reduced heating mode,
frost protection).
■ Your heating contractor can make fur-
ther settings for you during commis-
sioning.
You can change any settings individu-
ally at any time to suit your require-
ments (see chapter "Central heating").

ing).
