Heat controller not reacting to inputs/cant control it

[Jan Trubiny 0]

I realized something is wrong when the whole room was overheated.

HC was not controlling the flow of water and stayed open despite the temperature was much higher than the desired.

 

I tried standby/dismount, factory reset, remove/add to network, nothing helps.

What seems to be partially working is prompt for calibration, which controller attempts but according to HC3, it fails. When calibrating, the motor runs as usual (cant say what it does in reality though)

 

Despite all this, when i try to manually set some temperature or through app/interface, it registers the value on valve or in app but valve does nothing.

i just sorted it out. it is faulty valve which doesnt completely pull out when opened. controller could not calibrate properly and was not working (tried 2)
