Jumper Settings The jumpers that enable/disable optional control features are located on the right side of the main circuit board (see page 4). The factory default for all functions is "disabled" (each jumper will be on a single pin). To "enable" a function, simply take the designated jumper and place it over both pins. COOLING: A high voltage relay for filter pump control is usually required to implement this function. If Cooling is enabled, the Aqua Solar will cool the pool by turning on the filter pump and diverting the flow through the collector array whenever the "POOL" temperature is WARMER than the "Desired Temperature" setting AND the "SOLAR" sensor is COOLER than the pool water. RECIRCULATE FREEZE PROTECTION: A high voltage relay connected to the "FILTER PUMP" output and the AUX temperature sensor are required to implement this function. If enabled, the Aqua Solar will turn the filter pump on and operate the solar diverter valve whenever freezing conditions are detected (AUX sensor below 35ºF). See diagram on page 6 for typical relay wiring. When recirculate freeze protection is enabled and the Aqua Solar senses a freeze condition at the AUX sensor, it will circulate the pool water continuously through the entire filtration plumbing loop including the solar collector panels. While this type of freeze protection is usually adequate in relatively mild climates, it is extremely important that the AUX sensor be properly placed and that the homeowner realize that the system is unprotected in the event of a power failure. Hayward highly recommends that one or more "freeze snap switches" (model GC-3) be placed in areas with susceptible plumbing (example: areas that may be shaded, or get more wind exposure) and that these sensors be wired in series with the AUX sensor. Recirculate freeze protection is NOT recommended in climates where freezing temperatures are common or last for extended periods. WARNING--If recirculate freeze protection is NOT selected, then you are relying on the collectors naturally draining to provide freeze protection. It is very important that you use a non-positive seal valve or drill a hole in the diverter of a positive seal valve to allow the collectors to drain. This will NOT work if the collectors are located below the water level of the pool. CELSIUS DISPLAY: This will change the temperature display to degrees--Celsius. The factory default is degrees--Fahrenheit. SOLAR OVERRIDE: A high voltage relay connected to the "FILTER PUMP" output is required to implement this function. When "Solar Override" is enabled, the Aqua Solar will override the filter pump timeclock (external timeclock for AQ-SOL-LV or internal timeclock for AQ-SOL-LV-TC) and turn the filter pump on whenever there is a call for solar heating or cooling. During periods of on/off cloudy days this may result in the pump turning on and off multiple times. It is also possible that the pump could turn on during hot night conditions. To prevent rapid on/off cycling of the filter pump during cloudy conditions, the pump will also remain on for a minimum of 10 minutes, and will remain off for a minimum of 2 hours. 9 OPERATION The Aqua Solar is a fully automatic solar heating control which requires minimal set up or adjustment under normal operating conditions. Typically the following is required: 1. Set the main switch to AUTO 2. Set the "Desired Temperature" knob to the desired temperature for the pool 3. Set the time clock for the correct time, the desired hours of filtration, and "auto" operation (model AQ-SOL-LV-TC only) The "Heating" LED will show when the pool is being solar heated. If your pool has a pool sweep, the Aqua Solar will turn it off for approximately 6 minutes when solar heat is turned on. This will allow air to be purged from the system. Controls and Displays MAIN SWITCH ON: The Aqua Solar directs water through the solar collectors regardless of desired temperature setting. Both the "Heating" and "Cooling" LED's will be on. For model AQ-SOL-LV-TC, this also turns on the filter pump. AUTO: For normal operation. In this position, the Aqua Solar will operate automatically based on the solar and pool temperatures. OFF: The Aqua Solar ceases solar heating or cooling (if enabled). Recirculate freeze protection (if enabled) will still operate normally. This switch does NOT remove power from the unit--to service the equipment, disconnect power at the main circuit breaker. DESIRED TEMPERATURE Set the desired pool temperature. The digital display will show the exact temperature while rotating the Desired Temperature knob. The display reverts back to the default pool temperature display a few seconds later. TIMECLOCK (model AQ-SOL-LV-TC only) The time clock controls the hours of operation for the filter pump. The pump can be programmed in 15-minute intervals with multiple on/off periods per day.

OPERATION
The Aqua Solar is a fully automatic solar heating control which requires minimal set
up or adjustment under normal operating conditions.
Typically the following is re-
quired:
1.
Set the main switch to AUTO
2.
Set the “Desired Temperature” knob to the desired temperature for the pool
3.
Set the time clock for the correct time, the desired hours of filtration, and
“auto” operation (model AQ-SOL-LV-TC only)
The “Heating” LED will show when the pool is being solar heated.
If your pool has
a pool sweep, the Aqua Solar will turn it off for approximately 6 minutes when solar
heat is turned on.
This will allow air to be purged from the system.
Controls and Displays
MAIN SWITCH
ON:
The Aqua Solar directs water through the solar collectors regardless of
desired temperature setting.
Both the “Heating” and “Cooling” LED’s will be
on.
For model AQ-SOL-LV-TC, this also turns on the filter pump.

Jumper Settings
The jumpers that enable/disable optional control features are located on the right side
of the main circuit board (see page 4).
The factory default for all functions is "dis-
abled" (each jumper will be on a single pin).
To "enable" a function, simply take the
designated jumper and place it over both pins.
COOLING:
A high voltage relay for filter pump control is usually required to imple-
ment this function.
If Cooling is enabled, the Aqua Solar will cool the pool by turning
on the filter pump and diverting the flow through the collector array whenever the
"POOL" temperature is WARMER than the “Desired Temperature” setting AND the
"SOLAR" sensor is COOLER than the pool water.
RECIRCULATE FREEZE PROTECTION:
A high voltage relay connected to
the "FILTER PUMP" output and the AUX temperature sensor are required to imple-
ment this function.
If enabled, the Aqua Solar will turn the filter pump on and operate
the solar diverter valve whenever freezing conditions are detected (AUX sensor be-
low 35ºF).
See diagram on page 6 for typical relay wiring.
When recirculate freeze
protection is enabled and the Aqua Solar senses a freeze condition at the AUX sensor,
it will circulate the pool water continuously through the entire filtration plumbing
loop including the solar collector panels.
While this type of freeze protection is
usually adequate in relatively mild climates, it is extremely important that the AUX
sensor be properly placed and that the homeowner realize that the system is unpro-
tected in the event of a power failure.
Hayward highly recommends that one or more
“freeze snap switches” (model GC-3)
be placed in areas with susceptible plumbing
(example: areas that may be shaded, or get more wind exposure) and that these sen-
sors be wired in series with the AUX sensor.
Recirculate freeze protection is NOT
recommended in climates where freezing temperatures are common or last for
