Why does my Immergas ZEUS 24 kW Boiler temperature overload thermostat activate frequently?
Frequent activation of the temperature overload thermostat may be due to a few reasons: lack of water in the boiler, insufficient water circulation in the circuit, or a blocked circulator. To address this, check that the pressure gauge values are within admissible limits and ensure that radiator valves are not all closed.
What to do if the fan works but ignition discharge does not occur on the Immergas Boiler burner train?
If the fan in your Immergas Boiler is working but ignition discharge does not occur, the safety air pressure switch may not be changing contact. Ensure that: the intake/exhaust duct is not too long, the intake/exhaust duct is not partially blocked, the diaphragm on the fume exhaust is adequate for the length of the intake/exhaust ducts, and the fan power supply voltage is not less than 196 V.
