Wiring Wickes room thermostat

[dmx08]

Hi all,

would be grateful for some advice. Our room thermostat is faulty and I have replaced it with a new one. There are 3 wires, red, yellow & blue although the blue is cut short and wasn't connected to anything in the old thermostat.

There are 3 terminals on the thermostat and Ive connected the yellow to 'on', the red to whats only numbered as '2' and no cable in the terminal marked 'off'.

When I put the power back on after connecting, the boiler starts but the thermostat doesnt switch it off.. Ive tried other combinations with the cables but it seems to be either always on or not at all.

Should I be using the blue (neutral I guess) in the terminal marked 'off'?

any advice much appreciated.

what you are saying is you have connected red and yellow together,
terminal 2 is on.

red goes to 1 yellow to 2

red goes to 1 yellow to 2

exactly what I have done.. In theory it should work!

apologies, looks like I got them wrong. I have red in 2 and yellow in 1..
Im sure I tried all options but will try again.. thanks.

the old stat got wet when a the wallpaper around it was stripped off. It had worked perfectly until then. Hopefully will find time today to swap the cables around and see what happens!

FFS, is it the blind leading the blind here?

It doesn't matter which way round the cables are, as long as they are in terminals 1 and 2.

Your problems lie elsewhere, probably the motorised valve.

Check the fuse also

It gets better. If the boiler starts how can it be the fuse?
