Operation Sequence FAULT FINDING 100W By using the flow charts basic problems can be identified. If the particular fault cannot be immediately identified, follow the charts from beginning to end Before commencing, always check that the Mains is ON and the system controls are calling for heat, the gas cock is open. Test the electrical system for short circuit, polarity, and resistance before attempting any electrical fault finding.
100W FAULT FINDING Hot Water Operation Start with system and boiler cold, with the power ON and no Hot Water taps open. Then Use a hot tap to operate the boiler. Is 230V at L connection ? Correct Mains Supply. Check pressure and flow Open any Hot mains tap.
FAULT FINDING Pool or Space Heating Operation 100W Start with system and boiler cold, with the power ON and no Hot Water taps open. Set the system controls to call for heat. Correct Mains Supply. Is 230V at L connection ? Is there 230V to the pump Is the 2A PCB fuse OK ? Replace 2A PCB fuse.
