Troubleshooting

4.1

Identifying operating modes and resetting faults

In the event of a fault, the fault code will flash on the control unit display.
The programming unit shows faults as messages in plain language.
A fault is present if the display flashes and indicates something other
than the current boiler water temperature or a message related to
normal operation.
Example: "6A" = Burner has failed to ignite
▶ Press and hold down the "Reset" button for about 5 seconds to clear
the fault.
The display shows "rE" while the reset is being carried out. A reset is only
possible if a flashing fault indication is shown.
If the display then reverts to a normal operation message, the fault has
been eliminated. Should the fault recur, repeat the reset two or three
times.
Fig. 8 Clearing a fault with the Reset button
If the fault cannot be reset:
▶ Note down the fault message and notify your heating contractor
accordingly.
CAUTION: Risk of system damage due to freezing.
The heating system can freeze up in cold weather if
it has been switched off by a fault shutdown.
▶ Rectify the fault immediately and restart the
heating system.
▶ If that is not possible, protect the heating system
against freezing by draining the heating system
and hot water pipes from the lowest point.
More information about possible faults can be obtained from the
installation and servicing instructions and the control unit and
programmer documentation.
