12.11 FAILED START-UP
If during ignition no flame develops, the boiler will go into alarm condition.
12.12 ANTIFREEZE FUNCTION
If the probe in the boiler detects a water temperature of less than 5°C, the circulation pump is automatically activated to prevent
the system from freezing.
12.13 PUMP ANTI-SEIZURE FUNCTION
If the pump is not used for prolonged periods, it is activated periodically for a few seconds to prevent it from seizing up.
