The honeywell tradeline thermostat would work as a direct replacement (no mercury in the new ones), however if your using just heaters and no cooling system off of it, you could Heat only thermostat from honeywell that would replace your unit as well. Both at available at Ace Hardware with the heat only unity being roughly 7 dollars cheaper.

That thermostat should get power from 24V side of a transformer in the air handler. There should be a fuse in there on the PCB, but just as likely, there may be a 2-wire sensor in your drain trap that will shut it down if it senses water backing up in the drain piping. Clear that line from the outside of your house with a shop vac, cycle the breaker for the air handler if needed. You may also be low on freon, though, so a service call might be a good idea anyway.

site shows this thermostat is a non programmable unit and has been discontinued. none of the info sheets including a pdf shows a replacement battery. this thermostat operates off line voltage only. check for a control fuse or breaker on your heating unit.
