digital thermostat
I have a 20 year old trailer that has an old manual thermostat for the furnace. Can I just switch it out for a digital thermostat? I know I need to make sure it'll work with the number of wires curren...

NOTE: Even fresh batteries don't like being below 20F. Went to the trailer to do a little bit of work today, thermostat was cold and wouldn't start up. Now have lithium batteries in it.
