Hi, I’ve recently moved into a new build house which has dual zone heating. The problem is the upstairs thermostat controls both the upstairs and downstairs radiators and the downstairs thermostat doesn’t seem to control anything! I’m wondering if something has been wired up wrong... the system has 2x Danfoss HPA2 valves. I’ve attached a picture of the wiring in the junction box, can anyone see anything noticeably wrong with the way it has been wired? Many thanks in advance!
