how to wire sunvic tlx7501

[peter45]

hi
I have just bought the above room stat and i dont understand the wiring diagram. The old stat has 1 black 2 red and 2 blue wires and i am confused. One of the red wires i think is the switch wire and links the on/off. Could anyone give me a very basic instruction as to which wires i need and which i don't. Also which wires go to 1,2,3 on the new stat.

Thanks for any help

Your colours seem a bit strange Black, Red, Blue.

Where do these connections come from and what is the heating system.
How many cables is it and what colours are in each cable.

Just a Live and Switched Live Return needed with this stat, as it is powered with batteries.

See http://www.sunvic.co.uk/tlx7501rt.html

on the link you gave and on the wiring diagram what does the c stand for, which terminal does the live from the wall go to and which terminals do i link with another wire?

C = LIve.
2 = Heating ON (return to trigger system or boiler.

What heating system do you have and what colour conductors are in what cable, or is it conduit and singles.

Sorry the wires coming out of the wall are 1 red 1 black and 1 earth (i think) as this has a green sheath on it and is wired to a screw on the base plate. Please could anyone tell me which terminals to attach each wire too on the new sunvic stat. the old stat is a Satchwell tlx2329

Your first post said 1 Black, 2 Red and 2 Blue ????

If you only had the Red and Black connected on the old stat, then,

Live Red on C.
Black to 2.
Earth to earth terminal, if no terminal sleeve and fold back on iteself.
