Question

Hi,
The calibration process of the HC adjust his motion boundary to correspond to the mechanical stroke of the valve, but I think that most of the valve have a dead stroke at closed position, for sure my standard M30x1.5 valves have it.
What I can see when I'm listening the noise of the HC when he is working is that often he close completely the valve and when he reopen it because heating is requested by his regulation algorithm he not reopen enough to let the water pass through because he still working inside the dead stroke of the valve and never try again to open more until I give it a setpoint at least 3 or 4 °c higher than the room temp.
I think that the HC should monitor the impact of the stroke on the near temp to know that for example the first 10% or 20% of the stroke are not relevant for the régulation, or react faster and open more when he not detect heat change with it's internal sensor who is near from the diffuser, ( temp at external sensor will probably not change fast enough for this purpose).
At this time clearly the operation of the HC is much worse than the one of a old and traditional thermostatic head. And far from what the spec was promising.
Fibaro should fix it fast because the winter is there and my home is not heated correctly and the investment cost is not negligible !
I have not picked this HC to reduce energy consumption because for this part I was happy with my previous Honeywell heads but to get more comfort (right temperature at the right time) and for now it's exactly inverted, every room are much of the time too cold or are heating too slowly thus I make energy economies but I have lost main of the comfort ...
Regards,
