I'm having trouble connecting my zone valves to my thermostat.
After having made a whole series of tests, it would seem that the thermostat remains blocked as in red on the image:
Is there a parameter that I have not entered correctly in the thermostat to control this?
I imagine that there must be a relay which switches from NO to NC depending on the heating demand.
For my part, I tested connecting to NO, my valves open and on NC, nothing happens.
There is therefore no current on the NC but permanently on the NO.
It's very annoying because for the moment, my floor heating is running non-stop ...
Anyone have a solution?
Thank you in advance !
