[QUOTE="ProDave, post: 435893, member: 6969"] I will try one more time to explain. You have one motorised valve for downstairs that you want to be energised when any downstairs zone calls for heat. you have one motorised valve for upstairs that you want to be energised when any upstairs zone calls for heat. You CANNOT do this all from one controller. Each controller has just one "call for heat" output and you need two. So you need two controllers, one upstairs one downstairs. Accept that fact, buy another controller and you will get your system to work as you want. Another way of explaining it would be if you had UFH upstairs and downstairs, then each one would have it's own controller. the only way it can work with one controller is with one motorised valve per radiator, and then the feedback contacts on the motorised valves are connected to give the extra logic that is missing from one controller.
