My speed control caps arrived but still sitting untouched.
My immediate concern yesterday was that I was not getting the expected temperature/humidity normalization between the two rooms. It turns out I was getting some circular air flow from the doorway where air was returning into the main room and the inlet port... Moving that intake port 8-10' further into the room reduced the circular flow and now I am seeing better temperature/humidity equalization.
My plan keeps changing, sometimes more than once a day. mounting this up in my attic gained some currency because it would simply breaking the circular flow. Downside to attic install is that ducting and blower would need to be insulated from temperature extremes (and I don’t want to muck around in the attic in July, in MS.)
Latest-best plan so far is to mount the blower up in my bedroom closet, then punch holes through two walls to route the duct through my bathroom and into the main room, near the heat pump unit. My wife wouldn’t like the ductwork in the bathroom, but not my problem…
Since I broke up the circular flow, the back bedroom temperature is lower, and main room humidity lower in the day time hours… Last night I had another epiphany about the heat pump and humidity. It appears that its energy saving mode just shifts the thermostat temperature several degrees and that works well ,,,,, BUT, last night I noticed when I shifted to energy saving mode, the room humidity bumped up about 5 points…. Apparently the cooling coils were wet, and when adjusted warmer, that moisture simply evaporated into the room…. In the future I will reserve the energy saving for night time hours when the main room dehumidifier is running, while the humidity was still moderate.
Last night after seeing the humidity jump, I reset the thermostat lower and the room humidity dropped again but much more slowly than it jumped up.
No hurry, but if my plans don’t change again soon, I may look into using a saber saw to cut some 8" holes in a few walls. My neighbor probably has one I can borrow.
