The function is always active, except in
the case of safety stops which impede the operation of the
recirculation pump and the NTC flow probe.

After the first two minutes of driving, the
following situations may occur:
Anti-freeze function
- if the pressure in the installation is sufficient;
If the central flow NTC probe measures a
temperature below 8 ° C, the circulation
pump remains in operation for 2 minutes.
A) if the flow temperature is higher than 8
° C, the circulation is interrupted;
- if the boiler is supplied with electricity; - if gas is
supplied.
Activation of frost protection is indicated on the display by the
symbol.
B) if the flow temperature is between 3 ° C and 8 ° C, another
two-minute circulation will be performed; if more than 10
cycles are performed, the boiler reaches situation C.
Frost protection is only activated if the boiler is in perfect working
order:
C) if the flow temperature is lower than 3
° C, the burner is lit at minimum power
until the temperature reaches 33 ° C.
