Anti-freeze and anti-sieze modes Provided the ON/OFF button is on (green light), the water pressure is adequate and the boiler has not shut down due to an error, the anti-freeze and ant-sieze operations will remain active. When the anti-freeze comes on, one of two codes will be displayed with the snowflake pictogram . The two possible codes are 05 (pump anti-freeze) or 06 (burner anti-freeze). 05 (Pump anti-freeze): When the boiler senses a temperature of 8°C or lower, the pump will run for 2 m
