Afternoon everyone, I hope your weekends going well, If anyone has a sec to give a helping hand it would be greatly appreciated.
I fitted a Baxi Megaflow 2 18kw system boiler Saturday, as a flush and replacement boiler job (yes i am GSR). I have never fitted this make/model of boiler before and possibly missing something obvious, feel free to add LOL and idiot to your comments hehe
On commissioning the boiler its set to de-aeration mode and then to self calibrate (quite clever!!) all external controls have been tested and function correctly but for the purpose of this issue i have refitted the link between 1 and 2 (heat call) and have permenant live, negative, earth at the boiler.
The display is saying 000, i have ran the CF mode 3-4 times now, the manual tells me that the boiler will return to normal/ operation mode after CF is complete, this takes approx 15-20 mins, i have no error or fault codes displayed.
Problem is the boiler is not firing at all as if there is no call, the manual tells me to set the heat temp to max (80) and the pump should run, i have a return temperature of around 35 degrees so the boiler is not to temp, there is no 230v at the pump but it functions correctly on CF test mode, rads all get hot etc.
Am i stuck in CF mode? is there a way i have to manually exit to user mode, i cant find anything at all in the manual apart from it should return after CF mode automatically?
failing that im guessing i have a faulty pcb?
suggestions and advice much appreciated,
Thanks in advance,
Col.
