Shutting down the heating system

If you intend shutting down your heating system temporarily, i.e. during a summer
holiday.

Start-up/shutdown

1. Check the heating system pressure
at pressure gauge A:
The system pressure is too low if the
indicator points to the area below the
red field (minimum system pressure
1.0 bar). In this case, top up with
water or notify your local heating
contractor.
2. Check that the ventilation apertures
of the installation room are
unrestricted.
3. Check whether the heat consumption
is assured by the heating system, i.e.
if radiator valves are open.
4. Press f.
The heating system starts.
The green indicator (ON indicator)
illuminates.
After a short while, the standard
display relating to the operational
status appears (see page 10).
