Quoted from djblouw:
Looks like you hooked the white wire to the wrong tab.
If you look at the 2 & 3 target (which you said are working) the jumper from 1 & 2 should follow the same logic.[quoted image]
That was it, thanks for the help! I misread the schematic in the manual the first time which is why I got it wrong. It seems to be working great now!
