Aqua Solar Pool Control
The GL-235 is a differential temperature control for solar heating of pools, spas, and hot tubs. It provides differential temperature control with an adjustable, calibrated water temperature high limit. Automatic nocturnal cooling (for pools that overheat in hot climates) and recirculate freeze protection functions can be enabled/disabled via internal jumpers. Input power can be either 115 or 240 VAC. The output controls a 24VAC automatic valve actuator. For older systems with 12VAC valves, an internal jumper can be moved to select 12VAC output operation. The GL-235 also has a high voltage output for controlling a filter pump or booster pump
America's best-selling solar control is designed for easy and dependable operation. Its microprocessor-based technology ensures reliable and accurate performance. Advanced features include differential temperature control, selectable high limit, programmable recirculation freeze protection, nocturnal cooling, and optional booster pump control.
