FROST PROTECTION
The boiler features a built-in frost protection mechanism: as soon as the
boiler temperature [NTC1 sensor] drops below 7°C, the central heating
pump is activated. As soon as the flow temperature falls below 3°C, the
burner starts up until the flow temperature rises above 10°C. The pump
continues to run for around 10 minutes.
If an outdoor temperature probe is connected, the circulator is activated
when the outside temperature drops below the preset threshold.
In order to enable the HeatMaster® TC boiler to protect the system
against freezing, all the valves of the radiators and the convectors
should be completely open.
