A CORGI friend who fits boilers has never been able to set these and used to use an ex Vaillant engineer but he has left London.
My ex trainee who fits some Vaillants avoids fitting this unit because of the problem of setting them.
Are they really that difficult to set then an installer should avoid them?
If the installer cannot set them then what chance has the householder?
