Hi guys have a honeywell v4073a valve this is now the third one thats been installed on my system in as many weeks. the problem is that the CH is still calling for heat when everything is off. Even with the valve wired with just the grey,blue,green, cables connected
there is still 150v back feeding on to the white and orange cores which when connected is still enough to drive the boiler. changed 2 valves and 3 heads. And they are all the same is there a bad batch? as all is ok with everything else.
