Fault Code TT - TEMPER BLOCKING

This screen indicates a temporary hold on the burner. There is a demand on the boiler, the pump is powered on, but the temperature of the water at the supply sensor is too high for the boiler to ignite. This occurs because the water temperature measured by the supply sensor is higher than the boiler temperature - ignition diff setting. This error will clear itself when the water temperature measured by the supply sensor is less than the boiler temperature - ignition diff setting.
