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. Programming unit and heating system faults are
indicated on the programming unit display if it has one.
More detailed information can be found in the program-
ming unit documentation.
Correcting burner faults
Caution: Risk of system damage from
pressing the reset button too frequently!
Too many resets can damage the burner's ig-
nition transformer.
V Do not press the reset button more than
three times in a row.
V If the fault does not reset after the third at-
tempt, try to localize and rectify the fault
with the help of the burner documentation.
V Notify a service engineer if necessary.
V Press reset button [1] on burner.
Caution: Risk of system damage due to
freezing!
The heating system can freeze up in cold
weather if it has been disabled by a fault
shutdown.
V Rectify the fault immediately and restart
the heating system.
V If this is not possible, protect your heating
system against freezing by draining the
boiler, the heating system and hot water
pipes at the lowest point.
