Hello everybody,
It’s makes now 2 years that I used FGT thermostatic valve to manage my heating in my house. During these years no issues at all.
And following the upgrade of firmware of my HC 2 and of my FGT, ( HC2 4.6 and FGT 4.7 ) all my FGT are no more usable.
I do see a change of temperature when I reuqest it, but motors are not moving every time. If I move from 19 to 21 for example, nothing move. I have to put the valve at maximum, to hear the motor moving, or to close it.
Sometimes when I request a change of temperature, the valve do a calibration sometime not.
The external button to pilot the valve is no more working on all my valves. Not possible to request a manual calibration for example.
I tried to reset to factory, reinstall it, it worked for a couple of hours, and again, no possibility to use external button, and very strange behavior.
I started with one FGT, and weeks after all my FGT start to show the same issues.
I can’t add a sensor on it, because the external button is not working.
On the HC2 interface, expect some calibration failure I don’t have any alarms.
Currently I removed all FGT head, because the manage was no more possible.
Did someone experience this kind of problem, or have an Idea of what I can test, do ?
thanks for your help.
Arnaud
