Switching on and off

Starting up the heating system

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 pressure gauge.

2. Open the shut-off valves in the oil

pipes (at the tank and filter) or open

the gas shut-off valve, whichever is

applicable.

3. Switch on the power supply, 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 (see page 5).

The heating system and, if

installed, the remote controls are

now ready for operation.

Shutting down the heating system

If you do not want to use your heating system temporarily, switch to standby

operation (see ”Selecting the heating program”, page 7).

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 freeze-up protection of the system or to safeguard

the heat exchange surfaces.

1. Switch off the heating system

on/off switch ”8”.

2. Close the shut-off valves in the oil

pipes (at the tank and filter) or close

the gas shut-off valve, whichever is

applicable.

3. Switch off the power supply,

e.g. at the separate fuse or a power

supply disconnect switch.

The power supply to the system is

now switched off. There is no

freeze-up protection.

The green lamp (operating status

indicator) goes out.

The settings of the control unit

remain intact.
