I went ahead and had the Evohome system installed recently, with hot water kit and 8 HR92's. 7 of the 8 zones are working fine, but 1 zone (always the same one) keeps demanding 100% even though the measured temp is above the setpoint.
For example setpoint is 16, measured temp is 16.5, radiator is cold, demand is 100%.. If I switch the HR92 OFF then demand drops to 0%, manually override it demand drops to 0%
I tried unbinding the HR92, replacing it with a spare and binding the new one in. Made no difference so not a fault with the HR92
Removing the HR92, refitting and performing sync did not help
Enabling "stroke" hasn't helped
I tried removing the HR92 and placing it in a different (working) zone. just to eliminate the possibility of a comms/reception problem. Made no difference
So I'm a bit baffled now as to what the problem is. Especially as all the other zones are functioning as expected. Any idea's ?
