We have an old Honeywell thermostat downstairs to control the temprature. Upstairs (in the airing cuboard) we have a digital programable control to turn on/off the c/heating & hot water.
We'd like to replace the Honeywell thermostat with a more modern digital model. There's 3 wires (red, yellow and blue) which go to pins 1, 2 & 3 on the back. Is this a fairly straight forward DIY job or should i get a professional in?
thanks in advance
