Duo-Therm Thermostat

Since my t-stat took a hit over the weekend, I've been looking replacements for it. My "repair" seems to be working just fine, but I think I'd feel more comfortable with a new t-stat. I can find what looks like an identical replacement unit online, but in my reading, I remember that someone had remarked about a new Duo-Therm t-stat that appeared the same but was not wired like the original and they had to do some rewiring of their A/C units and furnace to get it to work. Mine looks just like this one on Ebay:

Duo-Therm 5-Button Thermostat



...but as far as I know, mine doesn't have a sensor that auto-cranks my generator if it loses power. This says it does and I honestly don't know if it would be a direct replacement.

Anyone with any experience????

    The 5 button CCC wall tstat. They are ALL the same. As to Auto Genstart and Heat Pumps and other features, THAT is controlled by other control boards in the RV. But, the only thing the 5 button does is respond to the existing various Dometic control boards and THOSE boards tell the tstat what they do. You buy a new 5 button and then do a reset so it will download the various features of your existing AC/HP control boards. You CANNOT use the current 12 button CCC programmable tstat. The 12 button will not respond to your existing control boards. Doug

    I just clicked your link. The list of so called features is VERY misleading. Yes, the 5 button has the capability, but ONLY if the other features and control boards are installed on the RV for those features.
