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 a

- 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.

They are easy to install. Just follow the directions that come with
them. Make sure you buy one that is compatible with your heating system.
The will have information about that on the package.
