Starting the heating system
1. Check the heating system pressure at the pressure
gauge. The heating system pressure is too low if
the indicator points to the area below 15 psi.
In this case, top up with water or notify your local
heating contractor.
2. For room air dependent operation:
Check that the ventilation apertures of the boiler
room are open and unrestricted.
Note: With room air dependent operation, the
combustion air is drawn from the boiler
room.
3. For Vitodens:
Open the gas shut-off valve.
Note: Ask your heating contractor to explain the
positioning and handling of these components.
4. Switch ON the power supply, e.g. at a separate
MCB/fuse or a mains isolator.
5. Turn the ON/OFF switch "8" ON. After a short time,
the standard menu is displayed (see below) and
the green ON indicator illuminates. Your heating
system and, if installed, your remote controls are
now ready for operation.
Note: Slide the black control cover outwards to
access the ON/OFF switch.
Standard menu
Note: If your heating system has 2 or 3 heating circuits:
