Where is this cabin located? What's the typical humidity there?

Re: Help Sizing a Mini Split System
The current version of Mitsubishi's design software, Diamond System Builder, does mini & multi splits and is freely available at mylinkdrive.com (or trane.mylinkdrive.com if you prefer). It won't help with the sizing, but it will guarantee that everything's compatible, including over/under committing indoor sizing vs outdoor sizing.
Mitsubishi/Tranes are more expensive, but they make up for it with better install training, tech support, & parts availability.
I'm not a dealer, but I have taken the VRF install courses. Very hands-on.

the computers that control everything require a clean sign wave.

Re: Steam pressure question
5 psi steam pressure will cause water to stack up about 11 ft. above the water line in return piping ("A" dimension). Chances are the water will be up into the main if not the first floor by then, so there will be plenty of banging.
Re: woods style pump coupler
unless you have the tools and training it’s best to hire an alinement contractor.

you have an after market motor. That diagram can’t be used!

Re: Looking for help with my AC condenser
With separate caps and a single cap wire from the fan motor you have to run T1 to both caps or jumper between the 2. Most caps have terminals that accept multiple quick connect terminals.

Re: chillers
look at the sweat on the braided flex line and stains on insulation. If you have exposed pipe higher up, it will sweat and drip down. The rusty flex flange says a lot. Do you have a water meter on the chilled water make up line? Do you record the meter reading weekly?
