Hi All
Help required if you can, so I have a multi zoned UFH system (6 zones ) on an S Plan. The basement UH8 works perfectly with all Therms down on temp power light only on, if temp pushed up then that relevant zone comes on and the pump and valve light comes on as should and when shut down goes back into standby mode with the power light on only. So heres the problem zone for the first floor when heating is called for the pump valve and zone illuminate as should but when switch off the zone light fades out extremely slow but does eventually go out but the pump and valve continue to run. This is happening on two of the six UH8's and they are brand new.
