Troubleshooting

Two type of fault are distinguished:
• Burner faults and
• Control and heating system faults.
If there is a burner fault the fault indicator lamp on the burner comes on
( burner documentation). Such faults can generally be reset by
pressing the reset button on the burner. Controls and heating system
faults are indicated on the controls display if it has one. For further
information see  controls' documentation.
Correcting burner faults
CAUTION: Risk of system damage due to too many
resets
Too many resets can damage the burner's ignition
transformer.
▶ Do not press the reset button more than three times
in a row.
▶ If the fault does not reset after the third attempt, try
to localize and rectify the fault with the help of the
burner documentation.
▶ Notify a service engineer if necessary.
▶ Press reset button on burner.
CAUTION: Risk of system damage from freezing.
The heating system can freeze up in cold weather if it has
been disabled by a fault shutdown.
▶ Rectify the fault immediately and restart the heating
system.
▶ If this is not possible, protect your heating system
from freezing by draining the heating system and hot
water pipes at the lowest point.
