BOILER PROTECTION DEVICES NOTE - ERROR 804: TO CONNECT THE BOILER TO ELECTRONIC SOLUTIONS FOR SOLAR MANAGEMENT OR IBRID SYSTEMS (ONLY FOR COMBINATIONS NOT ADMITTED), IT’S NECESSARY TO INSTALL A CLIPIN SUPPLIED AS ACCESSORY CODE 3319171. Anti-frost Device The anti-frost function acts on the central heating flow 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 (fixed) the boiler will check the following: a) if the central heating flow temperature is > 8°C, the pump stops; b) if the central heating flow temperature is between 4 and 8°C, the pump will run for another two minutes; c) if the central heating flow temperature is < 4°C, the burner will fire (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. 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.
