Eric, if it aint broke, dont fix it.... out of site out of mind comes to thought here.
You've been very patient working through this and I admire you for that. So with that said, dont think I was suggesting you "SHOULD" be testing your ac bay's temp. It's already BEEN tested and again, you have the "proof".
Here's a situation I ran into with my Scamp's Coleman roof-mount A/C! When I bought my Scamp
and ran the a/c, the thermostat would kick off and stay off 10+ min and it would get "humid" in my Scamp
before kicking on again. Now, some have suggested to "drain the water" which possibly would have worked ALTHOUGH, when it's humid like now, it runs off my Scamp
like a waterfall. People in "dry" heat have NO idea what we're talking about here
I brought up about my comfort in our Scampers@Yahoogroups.com
. Someone there pointed me to the Casita
forum. A guy had "cut" into his electrical
, installed a relay that's activated by a Hunter digital thermostat mounted at the bed. WOWWWWW... To make a long story short, I can control the temp of my Scamp winter OR summer now within 1 deg if desired. The Hunter has a built-in "delay" so it's a 3:40 min before the unit will cycle on again to protect the compressor. But the humidity is GONE and it's more comfortable now than my bedroom! My Coleman has a heat strip and it can be controlled the same way...just flip the Hunter on "heat".
Now here was my dilemma with THIS installation:
WHERE it's mounted (the same with Scamp's furnaces at the end of the kitchen cabinet), it was a total failure at the first. An INTERNAL (yes internal) miniature fan IN the thermostat fixed it instantly and it's been in use about 5 yrs now...NO problems. And Eric that's why I can appreciate your super effort for your design.
And as I feel with Carl's problem? My friends: "air flow" is EVERYTHING....
