Ferroli Maxima 35C, I may have corrupted my M button menu setting

Resolved Question:

Ferroli Maxima 35C, I may have corrupted my M button menu setting as the boiler does not go into standby mode when demand is satisfied .The boiler shuts down but the delay heating symbol is not illuminated and the CH pump will not time out as it used to, it now runs on.Any help appreciated.

Were you in the OTC (outside temperature compensation) menu at the time?
Customer: replied 3 years ago.
Fortunately I recently bought a complete boiler which was condemned by an noPower engineer because he was unable to replace the main combustion chamber gasket claiming nPower were unable to acquire a spare gasket.Consequently I have changed the control board and this cured the fault,so it was an excellent buy for spares at just £28.and has provided me with a test bed to work on without jepodising my own boiler.
Expert:  Andrew Smith replied 3 years ago.

I understand, have you cured the problem yourself by swapping components?

Customer: replied 3 years ago.

Thanks for your interest,as I said swapped main control pcb boiler now ok
