Frequently Asked Questions
Will this thermostat work with my Atwood furnace?
Yes, this is a genuine Dometic replacement part compatible with Atwood RV furnaces (Dometic acquired Atwood). It works with single-stage forced air heating systems that use standard RV thermostat wiring.
Does this thermostat require batteries?
No, this is a mechanical analog thermostat that draws power directly from your RV's 12V DC system through the furnace wiring. There are no batteries to replace.
Can I use this to control both my furnace and air conditioner?
No, this is a heat-only thermostat designed exclusively for furnace control. If you need to control both heating and cooling, you'll need a heat/cool thermostat model.
What if my existing thermostat mounting holes don't line up?
This thermostat is designed to fit standard RV thermostat wall plates. Most Atwood and Dometic systems use compatible mounting patterns. If you're replacing a very old thermostat, you may need to verify mounting hole spacing or use the existing wall plate.
