Digital Thermostat

Most old thermostats were 'in' on 1 and 'out' on 3 so i would say Grey should be SL, when you tested it did you have timer calling for heat?

It should be mentioned that if you get it wrong you could cause ££££££ of damage to your boiler/system controls....grey pink blue or fluffy dice...you should check the source of each cable...I could probably tell you from what you described which is which but in the same breath have come acoss many installations were it has been done by a colour blind dyslexic while viewing stat through a mirror ...

I tried Grey and black seperate but nothing happened. I am thinking of changing to a simpler digital because this Salus RT500 is a bit complicated for us. Will try wireing again

The rt500 is a programmable room stat, What type of boiler/system do you have.

You will more than likely need to place the receiver near the wiring centre and re-wire the system somewhat.

You may need just a basic room stat with batteries for the display and 2 wires to control the heating

unless you have the heating through the night it shouldn't active the relay etc
