    The Hayward Aqua Solar Series Operational Details: 

    Automatic Heating
    If the collectors are warmer than the pool water by 4ºF or more, and the pool is below the selected desired temperature, the valve will rotate allowing heat collection.

    The heat collection stops when the solar sensor temperature falls within 1.5º of the pool temperature or the pool temperature exceeds the selected desired temperature.

    Automatic Cooling [Field selectable option]
    If the collectors are cooler than the pool water by 8ºF or more, and the pool water is above the desired temperature, the valves rotate allowing cooling via the solar collectors.

    The heat dissipation continues until the collectors rise to within 3ºF of the pool temperature or the pool temperature is lowered below the desired temperature.

    Single Setting for Desired Temperature
    The Aqua Solar is set by a single dial adjustment with the desired pool temperature clearly indicated. The dial is calibrated with the temperatures from 70ºF to a high 104ºF for quick and easy, user-friendly operation.

    The temperature set indicates the desired pool temperature. The Aqua Solar will automatically determine if the water should be heated or cooled, thus maximizing the solar 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.

    LED Indicators
    Show the status of the system operation; seven highly visible LEDs show:
    1. Power to control
    2. Power output directing valve and/or pump to collect heat [heating]
    3. Power output directing valve and/or pump to dissipate heat [cooling]
    4. Sweep interlock indicating the pool cleaner pump is in the lock-out
    4. time allowing for flow to establish previous to turning on
    5. Sensor fault indicator shows pool sensor not operating properly
    6. Sensor fault indicates open or short circuit
    7. Sensor fault for auxiliary sensor

    Valve Output
    valve output on the Aqua Solar is the industry standard 24 VAC. Output is fuse protected

    Recirculation Freeze Protection [Field selectable option]
    Turns the Aqua Solar output ON, directing warmer pool water through the collectors when near freezing temperatures are noted at the auxiliary sensor.

    The Aqua Solar allows recirculation when the aux. sensor falls below 34ºF and wills stop recirculation when the temperature rises to greater than 36ºF. Two 10K Ohm sensors are required for operation. 

    One or more freeze snap switch sensors are also recommended if freeze recirculation protection is utilized. Important: See instructions before using freeze recirculation.

    System Operation and Test Switch
    Allows the user to manually override the automatic function of the Aqua Solar to verify the operation.
