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.
