Do you still have the bridge wire in at the wiring center?

Sorry for my ignorance, do you mean the short at the end of the room thermostat wires?

Yes the old wall thermostat is removed and is shorted out at the terminal block. Before I did this, I had set the old thermostat to maximum. Disconnect inv and shorting out at the terminal block made no difference to the operation of the CH.

So I guess the next step is to fit another motorised head unit (I do have a spare) ?

Puzzling results. Different under the same conditions.

With CH only 'on'....

1. Original test

2. Latest test

I can only explain this by saying the the Hive contacts are really bad at gripping the wires, no matter how tightly you screw them up. A couple were loose but I think they are definitely anchored in now.
