Hi, I need to change my central heating room thermostat and am considering a digital type. My current stat is 2 wire mechanical type and i have been told i need battery powered type as there is no permanent live feed.
Is this a simple DIY job and does anyone have any suggestions as to which type / maufacturer would be best as there seem to be hundreds?
Don't think there is a lot to choose between manufacturers. The only difference really is do you want a straight forward room stat or do you want a programmable one where you can set different temperatures at different times of the day.
Just leave the neutral unused. It does not effect the boiler operation.
