Hi,

I'd just like some help with rewiring a new programmable thermostat. I
think I know what to do but just wnat to be sure if possible.

Presently I have a standard Honeywell (T40) T6360B - the large dial
electro-mechanical type. I am getting a Horstmann Centaur 7, that has been
recommended in the group before. Apparently it's quite common for
installers to use standard 3 core flex to wire up the original thermostat
and these electronic replacements only need two wires. Presently the
Honeywell is:
No wires to Earth terminal, 'the Earth wire' to terminal 2, the Neutral wire
to terminal 3 and the Live wire to terminal 1.

Any idea which goes to which terminal on the Horstmann? I'm led to believe
'the Neutral wire' now on terminal 2 is redundant and the 'Heat Call' wire
(Earth on the flex presently) is likely to be required along with Live
currently on terminal 1?

Hope somebody can make sense of that?
