Operation Shutdown Error Table

Anti-frost Function

The anti-frost function operates on the central heating flow temperature when the electrical supply is turned on. If the primary circuit temperature falls below 8°C, the pump runs for 2 minutes. After circulation, the boiler checks the temperature:

• If central heating flow temperature is > 8°C, the pump stops.
• If between 4°C and 8°C, the pump runs for another two minutes.
• If < 4°C, the burner fires at minimum power until the temperature reaches 33°C, then the pump continues to run for two minutes.

If the flow temperature remains between 4-8°C, the pump runs for two minutes for a maximum of 10 times, unless a temperature above 8°C is detected. If lockout is caused by overheat, the burner is kept OFF.

The anti-frost function activates only when:

• The system pressure is correct.
• The boiler is electrically powered.
• There is a supply of gas.
