Aqua Solar Digital Solar Control System The Aqua Solar Digital Solar Control System is a differential temperature control for solar heating of pools, spas, and hot tubs. The Aqua Solar is available in 3 models; AQ-SOL-LV, AQ-SOL-LV-TC and AQ-SOL-LV-SP. These models provide differential temperature control with an adjustable calibrated water temperature high limit. Both offer a built-in digital display for solar, water, and ambient temperature information as well as programmable set point temperature. Automatic nocturnal cooling (for pools that overheat in hot climates) and recirculate freeze protection functions can be enabled/disabled via internal jumpers. The AQ-SOL-LV-TC additionally provides a filter pump time clock, programmable in 15-minute intervals with multiple ON/OFF times. The AQ-SOL-LV-SP model provides a solar priority function-one of the optional high voltage relays can be used to remove power from the conventional heater whenever solar heating is available. This maximizes the heat contribution from solar. Front panel indicator LED's also provide immediate feedback of system state such as heating, cooling, and sensor fault. Specifications Power: 105-130VAC, .5A 50/60Hz. or 195-250VAC, .3A 50/60Hz Valve Output: 24VAC, 20VA, .85A max. Industry standard 3 pin connector Relay Outputs: DPST isolated contacts; 3HP@240V, 1.5HP@120V, booster pump, pool sweep interlock, or filter pump; 1 relay supplied with AQSOL-LV-TC, maximum of 2; order relays separately (part no. AQRELAY); relays are industry standard Sensors: 2 required for "SOLAR" and "POOL" temperatures; 3rd sensor ("AUX") is optional-for display and/or recirculate freeze protection; (all sensors are thermistor type, 10K@25ºC/77ºF, additional freeze snap switches may be wired in series with the "AUX" sensor when used for recirculate freeze protection) Field Selectable options C/F Temperature display in Celsius or Fahrenheit (factory default) Cooling Enables or disables (factory default) operation to cool the pool Recirc. Frz. Enables or disables (factory default) recirculate freeze protection Solar Override Enables or disables (factory default) override of the filter pump relay when solar heat is available. Control Logic Heat diff.: 4ºF on, 1.5ºF off High Limit: 70-104ºF calibrated scale Recirc. freeze: On when AUX sensor less than or equal to 34ºF Off when AUX sensor greater than or equal to 36ºF Cool diff.: -8ºF on, -3ºF off 1
