Good morning All.
It is time to call on all those good looking helpful people out there (creep) & once again ask for advice. The problem is that we need to fit a new wireless central heating wall stat. At the moment we have a wireless Danfoss RET B+RF, this has become unreliable & needs replacing (have changed batteries) We have bought a Drayton Digistat +IRF RF710. I removed the old unit from its back plate & found the old & new back plates were identical apart from a few markings. I then changed old for new, wiring like for like : Neutral, Live, No. 1 empty, No2 Black, No. 3 Grey, & No.4 empty, No earth. I then fitted the unit & followed the Commissioning guide word for word. Trouble is the boiler wont fire up, although the flame symbol is showing on the unit.
Any help would be very helpful.
Thank you.
