Ok - I had to know first hand - not that I don't trust Rawlus
I called Dometic and got some additional information from a very helpful Erin at their customer support line. In order to use the digital thermostat with our A-Frame models that shipped with the analog thermostat, you would have to REPLACE THE ENTIRE COOL CAT UNIT! Wow! There's an expensive upgrade. Here's what I learned.
She was able share the installation document for the latest dometic cool cat heat pump / ac units (series 441004). The manual was for the 441004.701 system. On the last page they show the installation of the thermostat (SZLCD Thermostat) and it is only a 3 wire install (+12, -12, COMMS). So basically instead of having connections for all the various functions (HP/HS, +12, Cool, Furn, HIfan, Fan, Grnd) this digital thermostat has only power and communications. I haven't confirmed the analog connections on my thermostat, but that seems reasonably accurate.
SO, even IF you bought the LCD WITH Control Kit I don't think the Dometic conversion would work in our AFrame units.
