This program controls an ExtremeReactors reactor with little efficiency loss in the form of a set/reset latch.
It doesn't change control rod settings and works by only turning the reactor on or off at set internal battery levels.

• The percentages shown in the image above are the recommended settings but if you have a big reactor with a much higher reactivity you might want to lower the reset signal's trigger percentage on the left side, because the reactor will produce more energy while it's turned off for a short while.
  Inversely if you want to min-max or have a smaller reactor you might want to increase the reset signal's trigger percentage and decrease the set signal percentage on the bottom side.

• If you want to tidy it up a bit more, you can set the OUTPUT variable to back and place the redstone port that controls whether the reactor is on or off on the back of the computer.
  Then, for symmetry, move the set signal at the bottom to the right side of the computer and set the SET_INPUT_SIDE variable to right.
