The boiler was wired with the vailant bus controls but never worked very well, so I’ve replaced it with a hive, all the controls and motorised valves operate as they should and the RT connection on the boiler is live, but the boiler wont fire up what so ever, I’ve took out the 24v link and left the burner in one. I factory reset the boiler in case it was still set up with the old controls but still nothing seems to work. Cheers
Oh yeah forgot to say it’s coming up with error f1505 gas inlet incorrect
