Pre-Hayward GL-235 Diagrams & Data

Note: The wiring diagrams above can be used for Model PCS3 and Model PCS2 solar pool heaters from SolarAttic. The "Current" and "Pre-Hayward" diagrams show two slightly different models of the GL-235, which used different physical positions for connecting the temperature sensors. However, wiring terminals #1-6 remained the same for either model and the "Pre-Hayward" wiring diagrams can be easily adopted to the current model if desired. The specs for both versions of the GL-235 are essentially the same.
