Wild guess but could it be wired for two A/C units?
I think for starters I would try to match up the wires at the t/s with the wires in the ceiling fixture ie do a continuity check. Hopefully that would eliminate half of the wires to deal with.
there is continuity in the wires attached to the control board and the wires hanging out of the wall - to be attached to the t-stat
my question is, which terminals on the t-stat do the blue, yellow & green wire attached to the control board, attach to on the t-stat....
if our assumption is correct, the white wire on the control board isn't going to be used at the t-stat because it is for the heater
