In fact, after a bit more playing, they do all cause the boiler to fire, but only if there is a minute or so between turning one off and another one on. E.g Turn HW on, everything works. Turn HW off and then immediately switch downstairs CH on, boiler doesn’t fire. However, if I wait...

Okay, so I wired it up as suggested, initially without connecting 4 to PL. Hot water worked fine, reciever lit up, valve opened, boiler fired. I then tested the CH, both valves operate correctly, the receivers both light up and the boiler shows the radiator symbol but doesn’t actually fire. I...

Thank you - that animation is excellent, I now understand. I'll trace all of the wires back from the wiring centre this evening to check, but I am pretty sure that it is the same as the animation. :)

Again, thank you for the reply. I did mention that I had omitted the HW wiring because I was happy with how to wire it to the cylinder thermostat - my fault though, I should have made it clearer - apologies for any confusion. Will it matter that the boiler is connected to (4) if I link it to...

Many thanks for the helpful reply. The system is going to be used to control the HW, I just didn't include it in the diagram to try and simplify it. The call for HW comes from the programmer (1) and goes to the wiring centre (6) before running to the thermostat on the cylinder. This will be...

I did actually search for 'hive multizone' as my first port of call and read through all 2 page of results, they were mostly talking about . If you can point me in the direction of more helpful advice then I’ll gladly remove this thread. Alternatively, you could offer me some of your wisdom...

Hello everyone, First post so please be kind. I've recently moved into a new build with a dual zone setup as below (I believe it is S Plan): Worcester Greenstar 14i Honeywell ST9100 programmer by the boiler 2x Honeywell CM907 - one in each zone. I going to fit a Hive multizone setup with 2...
