Ventingprogram
When, on lling 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 tted, the three-way valve every 80 seconds to remove the
remaining air from the boiler. All venting points still have to be vented when lling the
installation. The boiler will be on standby after the venting program.
