Hi this may sound silly to all you plumbers in here but its seriously doing my head in. right, this is my question,
i have a vaillant combi boiler and a ultra steel 150l pressurized cylinder in my house, when it was fitted the plumber had suggested getting a combi boiler in case the tank ever failed, he has plumbed it so that the hw side goes straight to the hw out of the cylinder but has turned the hw off on the boiler, so not to constantly use gas when it is not needed, because of this setup having 2 motorised valves 1 for hw and the other ch, it was impossible to use the timers or programmer that fit onto the boiler so a heating sparky fitted a siemens rwb9 programmer under my stairs, obviously wired into the motorized valves for the 2 different ch and hw this works fine but i would really like to have a room stat as one was never fitted, now is it possible to get a 2 channel wireless programmer with a stat combined or would i have to just get a rf programmer with stat and only control the ch side with this programmer and control the hw with the old programmer i could have a conventional wired programmer but do they do these in 2 channel with a built in stat, or (sorry about this) should i get just a simle stat and wire this in to the programmer ( is this posibble, and is it easy? do you just attach the stat on to the ch side of wiring for programmer?????) any help would be appreciated thankyou....

thank you for your response,

can you recommend one?
Are they easy to fit? do i simply wire it in to the ch side of the programmer???

great thanks so i will only be able to control the heating side using the rf systems,( i take it there is no two channel systems rf?) now do i take a new set of wires from the programmer ( leaving the current wires already there) to the transmitter or do i remove the wires completely from my programmer and into the transmitter then into the programmer????? sorry to be a pest, if you could tell me the easyiest way to have a temperature controlled system that would be great.

right ok i have found other wire you speak of and yes it was the one connected to number 4 now when i install the tlx rfp it shows on there wiring diagram 3 wires neutral,live and output (call for heat) do i put number 4 into output the other wire (brown) into neutral and just pick up a live from the junction box??
PS where are you located? oh and if i used the tlx rfp as this is programmable would i have to leave my current programmers ch to on all the time??

PPS i cant thankyou enough for you info you have so far helped me loads..
