I broke my honeywell thermostat for good last night and I need a new one. My xh had bolted it to the coal bin on the side that I dump coal into it, and I was dumping a half frozen bucket of coal in and the vibration must have really screwed it up because it isnt working anymore and I cant see how to fix it. My keystoker came with this honeywell...I think this is standard. My question is, can I switch it out for a digital version or do I need to go with teh exact same honeywell? It will be $40 to replace it, but, I would love to go with a digital even if it isnt as accurate. I'm picking something up on my way home today but would love your input. I'm not prepared to spend too much on this right now.
