I noticed the new Manzanita micro manual for the PFC20,30,40 show a new control board with a second RJ45 connector, and 3 additional trim pots.
Looks like you can select 3 voltage settings and 2 current settings based on jumpers on the new remote control port!
I sent them an email to see if this board could be retrofitted to an older model. Seems like this board is more BMS friendly, I like the idea of being able to select different voltages without having to keep track of how many turns I put on the trim pot.
Select low voltage for day to day charging, select high voltage for balancing. You could have the BMS select medium voltage and low current if a cell goes VHC.
The new board is shown on the last page:
