Angry Replacing old CH / HW Programmer & Room Stat

I'm trying to replace a single channel (Water and Central Heating) Programmer and Room Thermostat.

The porblem is that room stat wireing only has 3 wires...Live, Neutral and Earth.....there is no "call" signal wire ???

How do I wire my new room stat, which requires a "call" signal, and how did the old one work ??

Are you in Europe?

mhandley:

You need to provide a lot more info if anyone is to assist you.

The answer to your question though can be found in the installation manual for the controller.
