room thermostat are calling for heat.
Resetting the Boiler
If a fault has occurred and the red LED is illuminated but
the pump continues to run, then switching the power off
for 30 seconds and then on again should reset the light.
This may be caused by the ambient temperature around
the boiler being too high. Check to ensure that any boiler
ventilation is not obstructed. If the fault reoccurs contact
your engineer.
IMPORTANT: Electrical safety checks should be
carried out by a qualified electrical engineer.

SIMPLE FAULT FINDING
If the boiler fails to start for no apparent reason make the
following checks before calling your service engineer.
Is green LED light illuminated?
No
Check for blown fuse or thrown power breaker. If
replacement fuse or power breaker fail again call service
engineer.
If the red LED is permanently illuminated contact your
service engineer.
Flashing red LED indicates an open circuit. The boiler
can still be operated. Service engineer should be
contacted.
