Hi,
I have an old beige colour Honeywell room stat that is connected with the blue wire to terminal 1, brown wire to terminal 3 and there is also a green and yellow that is not connected. I want to replace this with a Terrier TRT1
What terminals on the Terrier do I need to connect the blue and brown to and should I connect the green and yellow, assuming it is an earth wire.
I have posted the pics and wiring diagram. I cant find any models numbers on the Honeywell but it a standard beige/grey looking one
many thanks
