The Hayward Aqua Trol power supply control box is not universal across all models, so it is important to confirm which system you currently have installed before purchasing a replacement. Hayward manufactures the Aqua Trol for above ground pools in two versions: the Return Jet (RJ) option and the Hard Plumbing (HP) option.
The Return Jet (RJ) option attaches directly to the pool wall return jet fitting, while the Hard Plumbing (HP) option installs inline with hard or flexible PVC and includes a Flow Switch. Although the components look very similar, the internal circuit board and software calibration differ between the two options.
To ensure your system operates correctly, you must check the label on the inside of your current control box to purchase the correct replacement power supply. We only carry the replacement Power Supply Control Box For Hayward Aqua Trol RJ, which is compatible only for the RJ option.
