dry mode in mini-splits
I've been looking into the four brands I was told are good mini-splits - Sanyo,Mitsubishi, Fujitsu and daikin.
One of the questions I have about dry mode is if, say, I have the house at 75 F in the evening, and I put it in dry mode overnight - will the mini-split keep on doing its drying overnight, until it gets down to 64 F, or whatever the minimum temp is for dry mode? Or does it have some kind of internal set temperature for dry mode also?
So far, it seems from what the specialists at these various manufacturers have told me, that for Sanyo, Mitsubishi, and Fujitsu, the dry mode simply keeps on doing its thing, running slowly, until you get down to 64 F or whatever the cutoff is. Without basing how it works on the temperature. THe guy at Mitsubishi told me it cycles the compressor on for 3 minutes, off 3 minutes, unless it gets below the 64 F cutoff (or 65 F or whatever).
Daikin is maybe different. It says in their operation manual that "the temperature setting is lowered by 4.5 F" in dry mode. Meaning that if you leave it at 75 F in the evening, it would do the dry mode until it gets down to 70.5 F and then it would quit doing it. I guess (although she's checking on that).
Is Daikin really different that way, or do the other brands also have a feature where they have a hidden temperature threshold for dry mode, a few degrees below the set-point?
And, suppose you lowered the temperature setting to 64 F for a Daikin mini-split and THEN put it in dry mode. WOuld it be powerfully cooling down to 64 F, which is not what I want - or would it simply keep on doing its "dry" mode thing without quitting unless it got below 64 F?
