Atwood-Hydro Flame Furnace Thermostat Replacement

I currently have an Atwood-Analog Hydro Flame Furnace Thermostat and would like to replace it with a digital thermostat control. Atwood doesn't make one of furnace use only, is there a work around??

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)
