Please can someone help with a wiring problem.

I have a Honeywell Room Thermostat in the lounge which has two wires
(each with a red and a black inside so four inside) which go to the
heating control box in the airing cupboard.

I can't see where these should connect in the airing cupboard.

In the airing cupboard I have a Potterton EP2000 programmer and a
control box.

Thank you

Older thermostats have three 'mains' wires - ignoring the earth. A live
feed, a neutral, and a switch return to the pump. The person wiring yours
should really have used a triple and earth rather than two twin and
earths. One wire out of the four will be unused.

You'll need the appropriate wiring diagram for the type of installation
you have.

And some newer electronic ones as well.

What's the recommended wiring colours to use for this - I put the
receiving end of a wireless pair yesterday and used red for live, blue
for neutral and yellow for switched return. It sort of felt right as
an amalgam of the two colour schemes!

What's the recommended wiring colours to use for this -

It doesn't matter, anything live has brown sleeving on it, anything
neutral has blue sleeving on it and anything earth has green\yellow
sleeving on it no atter what the manufactured colours are.

That's what I'd use, but under the old colours the blue should have a
black sleeve on it to denote it's a neutral, and the yellow a red sleeve
to denote it's a live.
