Help needed
I have just bought a Honeywell cm67 programmable thermostat to replace an ancient Sunline Proscon and give me more control, problem is the Sunline has four wires Red (L), Blue(N) and Yellow + earth and the Honeywell has only two terminals, i have fitted the L & N as per the diagram but this just blows the fuse, can anyone help by telling me what i need to do with it to stop it blowing fuse's??
