Tuning performance of Dakin 8kw Altherma 3

I’d suggest leaving modulation enabled. It allows Madoka to override the flow target temperature based on the indoor temperature. A value of 10 corresponds to roughly 3c rise or fall in flow target.

I found it terribly crude - it adjusts in huge steps. AFAIK room temp has to shift by 0.5 degrees before it will do anything. Would seem much better if it added a degree to the flow temp after a drop of 0.2 degrees, rather than waiting for a drop of 0.5 degrees then adding 2.5 degrees to the flow temp.

But agree that it provides a bit of feedback while tuning weather curve, but once you’ve got the latter in place, room temp should be fairly stable and the modulation is rarely called upon.
