I am having an anomaly with the new MicroAir thermostat. The heat pump stops working (just blows semi cool air) and the stat freezes up when the outdoor temps get to be around 45 degrees or colder. The screen on the stat only lets you select heat pump operation or the one for the heat pump/AC operation. I have to turn it off, go to settings, do factory reset and then I can go through all the options including turning on the furnace.

I thought it might be something to do with the heat pump but when we first bought the trailer did our maiden checkout trip (3 days) with nights in the mid/upper 30s and the heat pump worked just fine with the Dometic stat. Just curious if anyone has had an issue like that with their new MicroAir or have used it in cooler temps without issue. I'm working with tech support for MicroAir but it is a slow process.
