When I get new Gree Crown units, the old Sanyo units will be removed and scrapped.

The reason for the 10 amp limit is because I think 15 or 20 amps at 240 to 250 vac,
is too much power. I believe it's not good for the system to be run that hard.
(I also do not drive the Prius C at 120 MPH).

The reason I believe this is because of my bad experience with an after-defrost high power run,
when the system cranked up so much that all the R410a was blown out
of a hole that appeared in a copper pipe coming out of the compressor..

I had to wait for a new outdoor unit to arrive (via slow-boat-from-China) and it also had the same over-speeding problem..
I didn't want it to suicide also, so I installed a 10A limit in the 230 supply..

In summation, if I can repair this board, I will increase the power limit to 13 amps,
to see if I can get less re-sets after defrost cycles..
I did repair the broken Sanyo (brazed the leak) and it's currently the one that got zapped by the grid blink.
Which seems to have occurred when there was about 3 inches of snow over the air-intake.
It might have been defrosting when the neighborhood power glitch hit us...
