I have four rooftop units, each with with a sensor which I assume measures the ambient at the air intake. The Micro-air seems to get stuck not turning on the compressor.
I contacted micro-air with this and inability to connect bluetooth so I could change router name to a 2.4 ghz connection. reset all did not work.
unplugging cat cable worked for an hour or so, problem came back. any help with these items appreciated. Contacted micro-air online but they did not followup.

Have you tried to set them at the furthest cold or warm(like 50 or 85, whichever you are trying to use)? 

The set up can be a little confusing if you have the floor heating with the AH as well. Can you send the settings(pictures) you are using for each zone? I can run out to the bus tomorrow and show you what I am talking about, but when you go to turn each unit on or off, you also most likely set up the Heat Pump and or Aqua hot. On my bus, this got a bit confusing as it's controlled with the thermostat, but most certainly AH floor heat. So 2 of the roof units will not cycle the compressor on heat as it's using the AH and the floor heat to heat. BTW, this is in addition to the electric heat on a separate t-stat in the galley, and in addition to the separate AH T-stat that controls the floor heat in the bath. I know... confusing.
