I have changed boiler so I have completely reset the thermostat to have it re-learn, especially the heating/cooling curve, so that true radiant can work properly. Yet, it's overshooting by 0.5 Celsius degree, sometimes also by 1 degree!
In the morning I want 20 Celsius degrees at 7.00am but when I wake up house is at 20.5.
Things get worst during the day: since I want 20 degree constant the whole day, the boiler turns on only if temp gets lower than 20 by a few degrees (not sure how much) but it should stay on just enough to re-establish 20 degrees, but by 7pm I have 21 degrees in the house.
