Hi,
I am wanting to change my old thermostat to a new programmable one (haven't chosen yet) but the problem is I only have a red and a black wire coming out of the old thermostat and all the new ones seem to need at least 3 wires. I do have a switch underneath the thermostat that turns a fuse on and off if this means anything?
Can anyone advise me on which thermostat to go for or help me with what the wires mean?
Thanks
