The initial start-up and matching of the control unit to local conditions and the
structural characteristics of the building must be carried out by your heating
contractor.
1. Check the pressure of the heating
system on the manometer.
If the needle is below the red
marker, the system pressure is too
low – in which case add more water
or contact your heating contractor.
2. Open the shut-off valves in the oil
pipes (at the boiler) or open the gas
shut-off valve, whichever is
applicable.
3. Switch on the power supply voltage,
e.g. at the separate fuse or a power
supply disconnect switch.
4. Switch on the heating system
on/off switch "8"; the operating
status is indicated by the green lamp
and, after a short time, the boiler
temperature appears in the display
window.
If you do not want to use your heating system temporarily, select standby
operation on the Vitocontrol-S, VD2/CT3/CM2 (see "Selecting the heating
program").
If you want to switch off only one boiler in the heating system, select standby
operation on the corresponding Vitotronic 100, GC1.

you should shut down the system.
We advise you to contact your heating contractor before and after shutting down
the heating system for long periods. Your heating contractor will take any
necessary action, e.g. for frost protection of the system or to safeguard the heat
exchange surfaces.
