Mine had a ridge vent and soffits on the sides.
I added the breathable foam at the vent to seal out any wind driving rain up and over.
Added continuous baffles from the soffit to the ridge vent to allow air flow.
Then used R30 batts unfaced. Made vapor barrier with plastic.
I did not see a P0 in the manual, but it says for P1 p2 p3 ....
disconnect the power then connect it again
turn back on.
if persists disconnect and call nearest customer service center.
I know that does not help, but that's all I can see.
I read the inquiry as setting up a mount a few feet away from the wall. ie in front of a shelf or something. The lines could still go out the back to the wall including the drain.
Now, if you mean something like in the middle of the room, then the drain line would be a concern.
I did a search for 24k Pioneer. don't know which one if they have different models.
Anyways, I linked to the install manual.
The Manual looked to be an exact copy of the Mr Cool.
??? maybe made by the same people ???
I just installed a mr cool diy.
Are you going to do it yourself ? I would guess yes since you are concerned about $100.
Most mini splits have the refrigerant in the unit. BUT not all have the lines already in a vacuum. The Mr cool is a diy, but you cannot cut the lines to length.
The others...
search cat 5 wire tracer

Just a tone generator
If you don't need to find the cable, I like using something like this tester...
In the barn, you will attach a wireless access point or a "router" acting like one.
Check the companies forum. You can find others with the same questions.
You may not need 2 nano stations. depending on the house construction, it may pick it up from the barn. I can get my house from more than 300 ft.
If one does not work, then get the second.
I've seen posts on this before here.
I suggest something from Ubiquiti.

This would be at the barn pointed toward the house and it would connect to your home wireless.
Then you would use any brand wireless...
