I've come across this old thread and I'm sorry I haven't said thanks to all that contributed to the topic and to ProDave especially. This was sorted with 2 wiring centres, one for rads upstairs and one for ufh downstairs. The rads upstairs all have ufh actuators on them instead of TRVs and each...

I now have 1 wireless stat set to zone 2 which controls 1 actuator/rad, I want to fit more actuators on each rad which will have their own zone/wireless thermostat. I only have one pipe loop for all the rads. That's why I'm trying to use actuators on all the rads just so I can acheive a multi...

Correct, but how can I stop heating one room when the others are still heating? How can I make one of the actuators shutdown whilst the motorised valve is still running?

I now have it wired like that, but it doesn't fully work as I want it, hence this thread..so, what am I missing? In my mind I need "something" in between the connectors of the zones and motorised valve, some sort of switch/relay, I don't know?!

Sharpend, that diagram is the standard diagram, you are not restricted on which zones you can use for ufh or rads. You can have 1 ufh zone and 7 rad zones or 7ufh zone and 1 rad zone.. The actual diagram that I have installed is zone 1 -> 3 actuators for ufh, zone 2 -> 1 actuator on 1 rad...

The uh8-rf is the newer version of the UH1-W, it does the same job I understand what you're saying as you can connect the valve for the rads where the manifold valve is supposed to connect. That would work, but I'm trying to see if that can be avoided. Thanks!

What would you suggest Sharpend ? That diagram above is what's come of the manufacturer's website. Like I said above you can programe the stat to do either ufh or rads. What I've done I've connected L and N from zone 2 going to 1 rad and also connected blue and brown from motorised valve to...

The wireless thermostats have a setting on them that you can choise if it controls ufh or rads, so when it's set to rads it will only liven up the zone that it's set to and not the manifold valve and pump. Yes, you can screw on the actuators on the radiator valve, the only downside is that it...

Thanks for your reply guys. Dave, I've started it logically and I'm not going to rip it out :). It did the job that I wanted it to up until I got another wirelless themostat for the UFH wiring centre. Where I'm a bit stuck is that I need some sort of device or something that can sit in between...

Hi, I have a combi boiler which has 2 motorised 2 port valves, 1 going to upstairs radiators and 1 going to ground floor underfloor heating. Before installing the underfloor heating I had a wireless room thermostat which controlled the heating. Heating on -> boiler on. (This has it's own...
