Starting up the heating system Vitotronic 300-K, MW1S
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 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.
Your heating system and, is
installed, the remote controls
are now ready for operation.
Shutting down the heating system Vitotronic 300-K, MW1S
If you do not want to use your heating system temporarily, select standby
operation on the Vitotronic 300-K, MW1S (see “Selecting the heating program”,
page 6).
If you want to switch off only one boiler in the heating system, select standby
operation on the corresponding Vitotronic 100, GC1.
If you do not want to use your heating system for a long period (several months),
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.
1. Switch off the heating system
on/off switch ”8” on all control
units.
The green lamp (operating status
indicator) goes out.
2. Close the shut-off valves in the oil
pipes (at the tank and filter) or close
the gas shut-off valve, whichever
applicable.
3. Switch off the main power supply
e.g. at the separate fuse or a main
electrical isolator switch. The power
supply to the system is now
switched off. There is no frost
protection.
Please note:
The settings of the control units
remain intact
