Dometic 3-wire T-stat...is there an upgrade yet?

[DougL3NC]

Is there an upgrade for the Dometic 3-wire LCD thermostat that came in my TT?

I took mine off the wall yesterday to upgrade to a residential thermostat and noticed it only had 3 wires. After scouring the internets, I quickly found 4 to 5 year old threads saying there is no upgrade yet for the new style Dometic AC units with the digital control boards.

My temps swing upwards of 15°, so we are either too hot or freezing our buns off!

Is there an upgrade available now, or has no progress been made in the last 4 years?

Below is the current thermostat...

Not to my knowledge.
I've been looking for one that can automatically switch from AC to heat as in the spring there are often 30 degree temperature swings. Need AC when going to bed but the heater by morning.
