4.11 Frost protection
4.11.1 The product's frost
protection function
The frost protection function switches on
the boiler and the pump as soon as the
protection temperature in the heating cir-
cuit is reached.
– Protection temperature: 12 ℃
The pump stops once the minimum wa-
ter temperature in the heating circuit is
reached.
– Minimum water temperature: 15 ℃
If the burner ignition temperature in the
heating circuit is reached, the burner
switch is switched on and continues
to operate until the burner anti-cycling
temperature is reached.
