so take a blue and ,red marker and mark the heat icon in RED and the cool in blueI've installed quite a few of the Pioneer mini-splits. I'm impressed with the functionality. I probably lean more toward cooling than you will (Southern Indiana) but they are my heat source in the garage. (The separate workshop uses gas heat). I'm in the process of installing 5 units in our house, using the multi-zone outdoor compressors, so two compressors. This will replace the 30 year old central AC, keeping the gas heat furnace.
My two complaints on these units are 1) the symbols for heat/fan/cool/dry modes on the remote are tiny, so distinguishing between the modes is difficult with older eyes, and 2) the lowest temperature you can set is something like 62 degrees, I would prefer to be able to set the garage to low 50's when I'm not using it. I end up using "Freeze Protection" mode which targets the mid-40's.
When the new workshop gets built, I plan on a 30k unit for a well insulated 2200 sq ft.
I'm *NOT* an HVAC tech, so take this with a that in mind, but my impression is that shorter pipes are fine for the charge. A fair amount of the charge is used in the units so the relative change per foot is small. The base charge is 30 ounces. The technical brochure calls for an additional charge per foot over 25 feet of 0.16 ounces per foot. So at 9 feet, you are at 16 feet less than the minimum charge, or 2.56 ounces over. That is a fairly small percentage. You are only 7 feet under the minimum pipe length they sell (16ft). I suspect that your are well within the normal operating range of the compressor.
do the dry in YELLOW for desert sand...
