Goldline AquaLogic Main PCB Circuit Board
Use this newest revision circuit board for AquaLogic systems to operate the new EcoStar variable speed pumps. This board is compatible with all date codes.
If your system has a "heater button" at the power center then you can use the GLX-PCB-PRO circuit board instead of replacing it with this one. Doing this will upgrade your system to a ProLogic from your existing AquaLogic. Heater button is located on the local display (mounted in subpanel). It is important to make sure you have a heater "button", not just a heater light. This button will determine if your system can be upgraded to a ProLogic which is only a few dollars more and will give you more options.
