I was reading about the 'Electric expansion valve' here,
Electric Expansion Valve Control - Feature Articles - Extra Edition - Air Conditioning, Heating & Refrigeration NEWS
How they help maintain a "constant head pressure", when I remembered
seeing one on the diagram of my new Sanyo mini-split..
It's down on the lower right side. Looks like it might be a Motor controlled valve.?
Anyways, I noticed a connection on the block diagram called, MVO. Lower right.
Magnetic Coil?? I never understood what that MVO was.. Is it the 'Electric expansion valve' control??
The other mystery is "Reactance" upper left side. Is that a pickup coil
for a spinning magnet on a motor? For speed control feedback?
