Mach 3 AC - wild temp swings
I think I know the problem, and the fix, but wanted to see if there's something easier.
Rooftop air has been running hard the past week. Temps in my slice of Northern Michigan have been in the mid 90s and humid to match. Rather than cool the house I've been doing some driveway camping to sleep in cooler dry air.
Problem is, the Mach 3 with it's ceiling controls are making that difficult. The thermostat seems to have a huge tolerance for cut in and cut out. It's not calibrated, but I've dialed in to about 70f. Problem is, it waits to about 75f before kicking in the AC, and then runs to about 60f before cutting out.
This hot and cold, hot and cold, hot and cold is really making it hard to sleep. During the cooling cycle I find myself waking up to clutch the blankets from the cold, then 30 minutes later, kicking them all off because it's in the high 70s again.
I think there's two problems. First, it's cold outside at night (77 right now at 11pm)... So the trailer cools quickly for such a huge unit (13500 btu for under 250 sq ft of cabin space?).
Second problem, the thermostat is getting blasted by the discharge air, so it "feels" cooler than the rest of the cabin.
Solution would probably be a wall mount thermo, so it could read a more average cabin temp. Not sure how to deal with the low outside temperature. If it weren't 90% humid outside, the temperature wouldn't be a problem.
Guess I'm being finicky!?
