Heat controller not closing



Hi there,


I'm running a heat controller on fw 4.3 with a issue (running on a non-fibaro controller). When installed on a valve with the RA-N adapter the controller stays in a open position, turning the knob to white doesn't do anything and calibration closes the valve for a second and than open again. After the calibration the controller still don't close.


I tried to install the controller on a other valve (one without the need for a adapter) and the controller works perfectly.


Hope somebody can help me to figure this out.


Cheers Alexander

Faulty adapter?

Try this adapter on a other device?

Connect adapter on Fibaro and see if its working also with counter force on it.

  • Hi Sjakie,


    Tried to apply some pressure to the knob and this seems to work. Fingers crossed that's it keeps working! :-)


    Cheers, Alexander

  • Does the heat controller only rely on the internal temperature sensor (of if bought the external bluetooth sensor)? Or is it possible to send temperature data from a other sensor?


    To make my question more clear: I have my radiator under a windowsill and noticed that the Fibaro heat controller doesn't respond as it should.  Is there a internal temperature sensor that the controller rely on? Or is it possible to have temperature data from my zwave network to control the heat controller?
