Required Settings (Heating/Cooling); Selecting The Heating/Cooling Circuit - Viessmann VITOCAL 300-G Operating Instructions Manual

Required settings (heating/cooling)

If you want central heating or central
cooling, check the following points:
■ Have you selected the heating or cool-
ing circuit?
For settings, see chapter "Selecting
the heating/cooling circuit or a sepa-
rate cooling circuit".
■ Have you set the required room tem-
perature?
For settings, see page 20.

Selecting the heating/cooling circuit

Central heating can be split over several
heating circuits (heating circuit 1, 2 or 3).
Cooling results either through one of
these heating circuits or via a separate
cooling circuit.
For all settings relating to central heat-
ing/cooling, first select the heating/cool-
ing circuit or the separate cooling circuit
to which your changes should apply.
