Condensing boiler not staying at max temp

[Agile]

We dont know the heat loss of the house or even the size and style.

You seem to have reduced d0 to 15 which is hardly any significant reduction.

Try setting d0 to 10 and see the effect of that. You need to keep the boiler burning for longer as every time it goes off there is no heat output at all.

Yes d15 was still a little high, I found at d12 the boiler wasnt quite getting to full 65 deg temperature (or perhaps very slowly). It needs to be 65deg output to heat the hot water tank that is reccommended to be at 60deg+ for legionaires, right?

d13 seems a better compromise, i just saw the boiler switch off rather than backing off.

Should really be set to 70.
