Atwood-Hydro Flame Furnace Thermostat Replacement

Any millivolt thermostat will work. Batteries will need to be replaced occasionally. We replace around clock switching for daylight savings time.

This thermostat will control the temperature and fan?

I suggest you use the forum search feature - lots of threads on this subject with detail answers which suggest which model and how to wire to replace the old analog thermostats. It's an easy, inexpensive upgrade that many wish they had done earlier.

Great idea, will try to search.
Thanks for your help!

No A/C Unit ????

If current t-stat only controls furnace then any Hunter/Honeywell/Lux digital t-stat that uses battery ($20-$25) will work. Most any hardware store

Furnace only uses 2 wires
The wire on your old t-stat on 'W' would go to 'W' on new t-stat
The other wire on old t-stat would go to RC/RH on new t-stat
(If you have 3 wires-----the wire on 'G' on old t-stat would go to 'G' on new t-stat >>>>>FAN wire)

That explains a lot! Thanks for taking the time to respond!
This is my first RV and I am learning a lot for this website!
I have replaced/upgraded my converter with information from others.

Oh, I forgot .... I have a roof A/C which has controls on it that are not connected to the thermostat.

The majority of RV furnaces do not have a separate fan function. The thermostat will control the temperature. The fan will start and run for 10-20 seconds before the furnace burner starts. This is to clear any residual gas in system. The burner will shut down when temperature is reached, the fan will continue to run in a cool down mode for 10-20 seconds.

The fan is NOT controllable on the standard RV Furnace and tstat. ALL you are doing is closing the connection at the tstat. You have 2 wires going to the Tstat and all the Furnace wall tstat does is open and close the 2 wires connection. Doug

Thanks to all for the info, better than going to school!
