Hi All,
Perhaps someone can help.
Our existing central heating thermostat (not programmable) is an old Honeywell dial type with 4 wires going to it (earth-blue-yellow-red) I have just bought a new digital one, the same make & size to replace it. I thought I would be able to fit it by fitting the 4 wires to the same terminals on the new one.
The problem is the new one only needs 2 wires, looks like live & neutral no earth. I would be grateful if somebody could confirm that I would only use the live (red) & neutral (blue) & then blank off the 2 remaining wires.
Thanks for any help.
