Radiator valves

[bailers]

Hi all,

I'm new to the forum but fairly established with home automation, lighting done and now moving on to heating. I use homeseer and although expensive I find it great. I intend on using Oregon temperature sensors in each room communicating with my rfxcom transmitter/receiver, I will be able to switch my central heating on and off via a relay on an io board. However what I really want to do is to be able to set my radiator valves open or closed in each room, I have looked at the wireless option and have decided not to go down that route as I want homeseer integration. What would be great if possible is powered replacement trv heads which I could also switch via relays, what I don't want to is to start hacking into my heating pipe work. Does anyone know of any thing like this that I could retrofit myself, preferably not too ugly as there is the WAF to consider!

Looking forward to your suggestions or critiques of my plans!

Regard
Chris

Chris_j_hunter,

Thanks!
That looks exactly what I am looking for!
Do you have any experience with this product? I am trying to work out how it works. From looking at the data sheet it seems I could set the head up to be normally open or normally closed, then when I apply a load (24vdc) it turns the valve to the opposite setting? How does it know when to stop I.e when the valve is fully open or closed? Also how does it turn back the other way?
Sorry for the questions, if you don't happen to know the answers I will email idratek and find out and then post their response back on this thread.

Thanks again
Chris
