Hi
Further to a recent post on rads taking 2 hours to heat up.................
I have started to look at the internal programmable functions of the boiler. What I noticed that the boiler often switches off during the initial heating of the CH water, long before the rads are hot. I have picked up that this is due to the recycling function of the boiler that has something to do with the efficiency of the boiler.
However, even after finding some explanation online, I dont really understand it!
I have learnt that I can change the d2 setting on the boiler and this appears to allow the boiler to burn for longer, but at least this is now getting the rads hotter!
Can anyone simplify the d2 control and the recycling function for me?
Also, someone suggested the pump speed could be changed, yet when I play with the d16 option its fixed at 0 = auto.
Thanks in advance.
