1.1.16. FROST PROTECTION
The boiler is protected against freezing thanks to
the P.C.B. configuration with functions that start
the burner and heat the concerned parts when
their temperature goes below the minimum pre-
set values, protecting the boiler up to an external
temperature of -10 °C.
The boiler starts when the heating water
temperature goes below
8
°C, automatically
starting the burner until the heating flow water
temperature reaches the 30°C and, in presence
of a return sensor, until the heating return water
temperature reaches the 20°C.
The system starts even if on the display appears
“OFF”, as long as the boiler is connected to the
power (230 V) and gas supply.
For long periods of standby, please empty the
boiler and the system.
If the temperature goes below -10° centigrades,
please fill the system with anti-freeze liquid
(CLEANPASS FLUIDO AG cod. 98716LA) and insert
a frost protection kit (cod. 82259LP).
