Hi
I have a Vaillant ecoTECH pro28 about 2 yrs old and want to replace a standard plug in time clock by installing a VRT392f.
I know its a simple swap the module and plug in, but do i have to reinitialise the boiler, or when i power back on will it just recognise the new controller?
The instructions appear to be for a first fit, not update.
Any help appreciated.
