(6 times red signal) Miscellaneous
The fault codes can be read with the
Recom
service software, a suitable
controller or a service tool.
Press the
J
key for 5 seconds: The status signals will
flash red quickly and the boiler will start its reset
procedure. The boiler will also start an automatic venting
cycle lasting around 4 minutes. If the error code continues
to display, search for the cause in the error table and apply
the solution.
The fault codes from the status signals are related to the fault codes
that can be read by the
Recom
software or a suitable controller. The
meaning of the error codes is given in the error table:
