replacing duo therm 3107612 analog thermostat

[fizikpal]

Good Day,

Looks like I might need to replace my thermostat. I would like to go digital and have all the same functions as my current thermostat (dual fan speed is a must).

Anyone have suggests and more importantly, successes?

Duo-therm to Digital with Hi/Lo Fan switch

Very easy, simple upgrade done my MANY...myself included.

Here is one
If this is a 4/5 wire configuration, then Hunter Douglas has a decent one for around 25 bucks. Since most home thermostats are 24V and your RV is 12V you will either want a dual voltage or battery powered one. There are several places on the web that have wiring schematics for connecting to an RV. The HD will need the addition of a small SPST switch to get both hi and lo speed AC fan settings. Following the instructions you should be able to do it in an hour or so.

Best to check with the ac / furnace mfgr for one that is compatible.
