I bought an HR91 to be a valve on a 2nd radiator in a room (and house) controlled by HR92s.
Its LEDs do what's expected but it didn't seem to move the valve at all.
I've cleared the binding and set it up as a test zone on its own but just put it on a desk, not on a radiator - that shouldn't matter right?
If I make the set point really high nothing happens: no whirring, no cogs moving and the controller says its heat demand is still 0%. It's reporting temperatures to the controller and I can see this on Domoticz too. Pressing the on/off button changes the set point on the controller/Domotics from 5 to 20 degrees. RF comms check is ok, though there was 1 error last night.
Ok I admit, that I went with the HR91 to save a few £s compared to the HR92. Furthermore due to supply shortages and price I actually bought a THR091 https://smile.amazon.co.uk/dp/B077BCY6RR/ intended for eastern Europe. The blurb indicates the difference is just the instruction manual language. Maybe there is a functional difference?
If nothing else hopefully this thread will be a flag to someone else thinking of doing similar.
Any ideas?
