Automatic heating If the solar collectors are warmer than the pool water by 4or more, and the pool is below the selected desired temperature, the valve will rotate allowing heat collection. This heat collection will stop when the solar sensor falls to within 1.5F of the pool temperature or the pool temperature exeeds the "desired temperature" set on dial. Automatic cooling (Field selectable option) If the solar collectors are cooler than the pool water by 6F or more, and the pool is above the selected desired temperature, the valve will rotate allowing cooling via the solar collectors. The heat dissipation will stop when the collectors rise within 3F of the pool temperature or the pool temperature is lowered below the set desired temperature. Single setting for desired temperature The GL-235 logic is set by a single dial adjustment with the desired pool/spa temperatures clearly indicated. The dial is calibrated with the temperatures from 70F to a high of 104F for quick and easy, user-friendly operation. The pool temperature set indicates set pool/spa temperature, and the GL-235 will automatically deter-mine if the water should be solar heated or cooled, thus maximizing the system capabilities. Terminal strip connections For input power, and sensor inputs. Controls also have industry standard 3 pin connectors for both forward and reverse valve actuator Read more...
