Commissioning

Filling the heating system

When all boilers have been electrically

commissioned as described above,

then the heating system can be filled.

Each boiler is fitted with a filling and

drain valve. The filling hose from the

water tap is then connected to it.

Venting program

When, on filling the system, the water

pressure rises above 0.7 bar, the

venting program will start automatically.

The program lasts approx. 13 minutes

and in doing so, turns the pump on

and off and, if fitted, the three-way

valve every 80 seconds to remove the

remaining air from the boiler. All venting

points still have to be vented when

filling the installation. The boiler will be

on standby after the venting program.

The automatic venting program only

vents the boiler and not the rest of

the installation.

For boiler checks please refer to the

chapter Checks prior to commissioning.

For any checks or setting changes,

refer to the Basic Settings chapter.
