Can't find the exact one but see D.017 in the attached (ecotec 627).

Ok it was actually set to 100%! I didn’t know. So I set it to auto. The actual value was 100%. I rebooted boiler put heating on and the actual value is still 100% despite being auto? Will it take time to tweak itself?If these code parameters are available on your boiler then note them with boiler on. The pump is probably a 7M one so the actual speed (%) will tell a lot.
1=1.97M, 2=2.52M, 3=3.43M, 4=5.05M, (5=7M)

No, because it's auto based on 27kW when your system likely needs about 10kWI know it has been mentioning pump setting might be too high. But heat pump is set to auto..is this typically ok?
That’s disappointing because you would expect auto to modulate based on the change in resistance. Eg trv closed/openNo, because it's auto based on 27kW when your system likely needs about 10kW
Yes, forgot about the TRVs, because if in control will/should just open a bit more to maintain the same dT to give the same mean rad temp, flow target temp will have to be increased to 60C, this will/should then give a return right down to 30C when/if they throttle in, that's why/how one can get very low return temps by using them.That’s disappointing because you would expect auto to modulate based on the change in resistance.
