Anti-frost Device
The anti-frost function acts on the central heating fl ow temperature
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 (fi xed) the boiler will check the
following:
a) if the central heating fl ow temperature is > 8°C, the pump stops;
b) if the central heating fl ow
temperature is between 4
and 8°C, the pump will run for
another two minutes;
c) if the central heating fl ow
temperature is < 4°C, the
burner
will
fi 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.
Activation of the anti-frost safety
device is signalled on the display
by the symbol
.
The anti-frost device activates only when (with the boiler operating
correctly):
- the system pressure is correct;
- the boiler is electrically powered;
- there is a supply of gas.
