REASON ACTION
CH Water temperature •Check no air is in heat exchanger / CH system
greater than 105°C •Check external pump operation
•Check PCB / X1C connector
•Check flow thermistor
•Check wires to sensors not crossed
• Check water pressure
differential incorrect • Check external pump / CH system blockage
• Check no air is in heat exchanger / CH system
• Check flow, and return sensors
• Check gas supply
Loss of flame signal during • Check gas service cock
• Check gas valve and lead
• Check detection electrode / lead
• Check PCB / X2A & X2B connectors
• Check spark generator /spark electrode
• Check mains earth lead continuity
Flue gas temperature greater • Check flue sensor
than 95°C • Check flue system
• Check no air is in heat exchanger / CH system
• Check external pump
• Check PCB / PCB connectors
REASON ACTION
Defective flow, return or flue • Check wiring to sensors
sensor or heat exchanger • Check PCB / X6 & X8 connectors
reached maximum safe • Check flow, return and flue sensors
working temperature • CHECK THERMAL FUSE IS OPEN CIRCUIT.
IF SO REPLACE HEAT EXCHANGER (SEE 10.8)
5 sec flame signal after burner • Check gas valve and lead
is switched off • Check PCB
• Check fan
signal • Check mains fan lead & connector
• Check low voltage fan lead & connector
• Check PCB / X3 connector
Internal error • Check PCB
• Turn CH control knob to reset twice to activate
• Check PCB
checking system • Check BCC is initialised
Incorrect / missing BCC • Reset or replace BCC
Faulty connector • Check PCB / X1A connector
• Check water pressure
• Check external pump / CH system blockage
• Check no air is in heat exchanger / CH system
• Check wires to sensors not crossed
• Check flow, and return sensors
• Check mains voltage
• Check PCB connectors
Defective power supply • Check power supply
• Check PCB / X1B connector
• Check PCB fuse
