Product Description
The AquaSolar® GL-235 is designed to meet the need for easy installation, dependable operation, and serviceability. The GL-235 incorporates unique, microprocessor based construction to ensure reliability and accurate performance. The GL-235 offers advanced operating features to provide differential temperature control, selectable high limit, programmable recirculation freeze protection, nocturnal cooling and optional booster pump control.
Hayward Item Code: GL-235 (NOT Included: Valve & Actuator)
Features
- Automatic Heating
- If the collectors are warmer than the pool water by 4° or 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 too within 1.5F° of the pool temperature or the pool temperature exceeds the “desired temperature” set on dial.
- Automatic Cooling (Field Selectable Option)
- If the collectors are cooler than the pool water by 6°F 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 3°F 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 70°F to a high of 104°F for quick and easy, user-friendly operation. The temperature set indicates set pool/spa temperature, and the GL-235 will automatically determine 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 operation and screw terminal connectors.
- LED Indicators
- Displays the status of system operation:
- Power to control.
- Power output directing valves and/or pump to collect heat (heating).
- Power output directing valves and/or pump to dissipate heat (cooling).
- Sensor fault indicator shows sensor(s) not operating properly.
- GL-235 Valve
- Output rating is the industry standard 24 VAC.
- Jumper switches the output to 12 VAC for compatibility with older valve actuators. Output is fuse protected.
- Recirculation Freeze Protection (Field Selectable Operation)
- Turns the GL-235 output ON, directing warming pool/spa water through the collectors when near freezing temperatures are reached at the collector sensor.The GL-235 will allow recirculation when the collector temperature rises to 42°F.
- Two 10K Ohm sensors are required for operation. One or more freeze snap switches are recommended if freeze recirculation protection is utilized. Important – see installation instructions before using Recirculation Freeze.
- System Test Switch
- Allows the user to manually over-ride the automatic function of the GL-235 and verify operation.
