The Dometic Comfort Control ll thermostat on my new CC would short cycle the A/C's. AC would come on, run for less than two minutes, shut off for the two minutes delay then turn AC back on. As if the temp., difference was way less than 1 degree. I counted 13 cycles in one hour. I got my dealer to send me a new thermostat, problem solved. These thermostats don't seem to be of very good quality. You can set the temp., difference 1 or 2 degrees for heat but NO adjustment in air conditioner mode. My AC's still cycle too often based on the previous two 5th. wheels I had that had single thermostats for each of the two Dometic AC's.
Wish you could use a good Honeywell thermostat but NO you have to use the overpriced Dometic made for the Dometic dual AC systems.
