Hello group. I had a typical round mercury wall thermostat until a drunk guy (no, not me :-) shoulder-planted into it and busted off the dial. I'm thinking of replacing it with a battery-powered digital model and a preliminary Internet search indicated it should be a pretty simple two-wire job. But after reading some posts in here I'm a little more concerned (I'm a fairly new homeowner and not super handy). Questions are:
- Do I need to cut the power to the gas boiler, the hallway, or both?
- I'm totally lost with voltage compatability issues - how do I determine this?
- If I totally screw this up, how will I know (other than the thermostat not working at all)?
Any help and advice will be greatly appreciated. Thanks in advance.
