Venting program
When switching on the mains power, following a power failure, if the water pressure is below
0.5 bar or if the high limit safety cut-out is reset, the venting program runs for 2 minutes.
The gas fan runs for the rst 30 s and then stops. The pump and 3-way diverter valve are
activated alternately. To cancel, press “reset”.
A fault in the heating system is indicated by a fault code
and the ashing service symbol.
The specialist contractor can quickly identify the fault
via the reset button and with the help of a fault code
table.
− In the event of a fault, please observe the
information in the installation instructions for
contractors.
− If a fault occurs in your heating system, please
contact your specialist contractor.
Please note:
Faultsmustonlyberepairedbyqualiedpersonnel.
If a lockout fault message is acknowledged sev-
eral times without the cause of the problem being
repaired, this can lead to component or system
damage.
The control unit automatically acknowledges faults such
as faulty temperature sensors or other sensors if the
part concerned has been replaced and plausible test
values have been supplied.
