Can anyone help? I've tried to install the above heating control but it doesn't seem to work. Not too sure if I've been wiring it up right! The old thermostat is a Honeywell T40 and I've got 4 wires going into it. Red into slot 1 (L), Blue into slot 2 (N?), Yellow into slot 3 (N?) and the Earth wire.
I don't really understand the wiring diagram given in the RTS5 instructions.
Please can anyone help?
