IMO....no.
We replaced both of our OEM thermostats with MicroAir units in our 295RL. We only use ours for AC, and not heat.
The positives we found:
Better modern user interface and control. Wifi accessable (would recommend a Wifi router for best mobile connection). Fairly easy install and setup. Works well for AC dump usage.
The negatives:
Costly replacement. When used with ceiling race track system (AC), have found some rooms colder than others. Using thermostat for manual settings, have found them to be a little quirky when switching modes (i.e. going from fan mode to fan/AC mode) - found letting screen return to menu by itself after setting mode saves manual mode settings... didnt read that anywhere (ours wont save using return function).
Wish it hads: Ability to add remote sensors like an Ecobee. Or, communicate or pair with another MicroAir thermostat in use. This is so it could adust for temp in a particular area when using the race track system. Also be more balanced cooling throughout RV - IMO, not different than performance from my OEM thermostats in that regard.
As for heat, we FHU camp and always use our electric fireplace and 2 heaters (1 IR wall mount and 1 ceramic portable in lower dinning room area) while running the (upper) bedroom AC fan only for race track circulation. Works well in cold temps down to low 40's.
