Anti-frost Device.
The anti-frost function acts on the central heating ow tempe

rature probe, independently from other regulations, when the
electrical supply is turned on.
If the primary circuit temperature falls below 8°C the pump
will run for 2 minutes.
After the two minutes of circulation (xed) the boiler will check
the following:
a) if the central heating ow temperature is > 8°C, the pump
stops;
b) if the central heating ow temperature is between 4 and 8°C, the
pump will run for another two minutes;
c) if the central heating ow temperature is < 4°C, the burner will re
(heating position) at minimum power until the temperature reaches
33°C, the burner will go out and the pump will continue to run for
two minutes.
If the ow temperature remains between 4-8°C the pump will continue
to run for two minutes for a maximum of 10 times unless a temperatu

re above 8°C is detected in the central heating ow, after this the the
burner will re. If lockout is caused by overheat the burner is kept OFF.
