Required settings

If you require central heating, check the
following points:
■ Have you selected the heating circuit?
For setting, see chapter "Selecting a
heating circuit" on page 22.
■ Have you set the required room tem-
perature?
For settings, see page 23.

Selecting a heating circuit

Heating can, if necessary, be split over
several heating circuits.
■ In the case of heating systems with
several heating circuits, for all central
heating settings, first select the heat-
ing circuit where you want to make a
change.
■ This selection is not possible in heat-
ing systems with only one heating cir-
cuit.
