Hi there
I would really appreciate help with this.
The thermostat for the downstairs heating in our house has never worked,
so
I took a look at it today. There are 3 wires going to it: green/yellow,
blue and brown.
The thermostat is a Drayton RTS1, which has 4 terminals: Neutral, Live, 3
(Call for heat) and Earth.
Currently, the wiring goes: Brown to Live, Blue to Neutral, and
Green/Yellow
to Earth.
This leaves nothing going to the 3 (Call for heat), which I guess is why
the
thermostat isn't working!
I'm guessing that one of the following is the case:
1) the green/yellow wire may actually be the 3 (Call for heat)
2) the green/yellow is actually neutral, and the blue is the 3 (call for
heat)
but I need to know how to check this without fusing the system! Also this
would leave no earth - is this likely?
I've got a digi multimeter, and there's 230 Volts coming down the brown
(when checked against either the blue or the green/yellow), so that's in
right, but how do I find out how to rewire the other two?
Many thanks for any suggestions.

I recently installed one of these on to my heating system. I'll see if I can
find the instructions for the thermostat if that's any use to you?
