The upper control board has a relay that supplies power to the Compressor. Then the Start Capacitor kicks in. I doubt your control board is the problem.

You just purchase a 12 button to 5 button change kit to install on the new Penguin to operate with your existing Tstat. This is best if you have 2 roof top units because you will have to replace the 2nd unit completely if you buy the new Penguin and the new 12 button tstat. 12 and 5 button control boards are not compatible. If you do NOT have 2 roof top units and just the One unit, then buy the new 12 button tstat as the change out kit and the new Tstat are about the same price. Doug
