Troubleshooting

1.   "Power" LED off:

Check main power circuit breakers.  Check to see if the Aqua Solar power is connected

to the LOAD side of the filter pump timer, in which case the Aqua Solar will only be on

when the filter pump is on.  Lastly, check the internal fuse which is located on the right

upper side of the main circuit board.  If necessary, replace the fuse with a type 3AG, 2

amp, slo-blo fuse, which is available in most electrical or electronics stores.

2.   "Heating" LED is always on:

Check that the switch is in the “AUTO” position.  Check the sensor temperatures:

The "Heating" LED should go off if the pool temperature is less than the "Desired

Temperature" OR if the solar temperature is less than the pool temperature.  If the

sensors appear to giving incorrect readings, check the sensors using the temperature/

resistance/voltage chart on the back cover.

3.   "Heating" LED never comes on:

Verify that the switch is in the “AUTO” position.  Check the sensor temperatures:  The

"Heating" LED should turn on when the pool temperature is less than the "Desired

Temperature" AND the solar temperature is warmer than the pool temperature.  The

exception is when solar override is being used (typically when the pool is filtered at

night, but the solar override function is used to turn the filter pump on during the day

when solar heat is available):  In this case, there is a 2 hour minimum off time to prevent

rapid on/off cycling of the filter pump.  If the sensors appear to giving incorrect

readings, check the sensors using the temperature/resistance/voltage chart on the

back cover.

4.   "Heating" and "Cooling" LEDs on simultaneously

This indicates that the main switch is in the "ON" position.  The Aqua Solar will

operate the solar valve and the booster pump (if installed) regardless of the sensor

temperatures.   Set the switch back to "AUTO" to resume normal operation.

5.   "Heating" and "Cooling" LEDs flashing simultaneously

This indicates that recirculate freeze protection is active (solar valve on, boost pump

on (if used), and filter pump on) due to the "AUX" sensor being less than 35ºF OR the

"AUX" sensor being disconnected OR any freeze snap switches wired in series with

the "AUX" sensor being open.  If  the "AUX" sensor is not connected OR a freeze

snap switch is open, the "AUX" temperature display will be " LO ".  The Aqua Solar

will continue this operating mode until the "AUX" sensor rises above 35ºF AND all

freeze snap switches wired in series with the "AUX" sensor are closed.  This function

operates regardless of the position of the "ON / AUTO / OFF" switch.

6.   "Pool Sensor" LED  on or flashing

      "Err" on the pool temperature display:

On continuously indicates a probable open circuit in the "POOL" sensor or wiring.

Flashing indicates a probable short circuit in the "POOL" sensor or wiring.  In either

case digital pool temperature display will show as "PErr".  The solar heating and

cooling functions will remain off until this problem is fixed, however, the recirculate

freeze protection (if enabled by the jumper) will still operate properly.  Use the chart on
