Solar Sync - Troubleshooting Guide

ProblemCauseSolution
Controller shows “NO SS” in display
  • Wires not properly connected to controller terminals. Sensor may not be installed.
Check the connection between sensor/receiver and controller.
Seasonal Adjustment too low
  • Region is too high
  • Water Adjustment setting is too low
  • Location of sensor does not allow for full sun
Make sure the controller dial is in the RUN position. Increase the value on the Water Adjustment scale (10 is maximum). Once the setting is changed, the controller will immediately be updated with the new Seasonal Adjustment %. Increase the Water Adjustment setting until the desired Seasonal Adjustment % is shown. If you max out the Water Adjustment scale at 10 and still require more Seasonal Adjustment, move down to the next lower Region (from Region 4 to 3, for example).
Seasonal Adjustment too high
  • Region is too low
  • Water Adjustment setting is too high
Make sure the controller dial is in the RUN position. Decrease the value on the Water Adjustment scale (default setting is 5). Once the setting is changed, the controller will immediately be updated with the new Seasonal Adjustment %. Decrease the Water Adjustment setting until the desired Seasonal Adjustment % is shown. If you minimize the Water Adjustment scale down to 1 and still require a reduction in Seasonal Adjustment, move up the next Region (from Region 2 to 3, for example).
Controller’s Seasonal Adjustment is reset to 10% and does not change
  • If using a wireless Solar Sync model, the communication has been lost between the sensor and receiver.
Once communication between wireless sensor and wireless receiver is re-established, the percentage (%) will increase for normal operation.
Rain or Freeze shutoff not activating
  • Rain Sensor Bypass Switch on the Controller is set to "Bypass" 
  • Remove jumper plate that is bridging the two SEN terminals on the controller
Set the Controller Bypass Switch in the “Active” position. Remove the jumper plate.
Run times for a particular station are too short/too long
  • Program Run Time too long/too short
Solar Sync provides a global Seasonal Adjustment to the controller. If a particular station has run times too long or too short, make the appropriate adjustment to the program in the controller.
Solar Sync still adjusting run times with sensor switch in bypass.
  • Solar Sync’s automated Seasonal Adjustment cannot be deactivated by the Bypass switch. The Bypass switch only controls the Rain/ Freeze shutoff function of the Solar Sync

Use controller delay feature. To access the Solar Sync Delay setting: 

  1. Place the dial in the RUN position. Then press and hold the + button. Next, rotate the dial to the Solar Sync position. Finally, release the + button. The following screen will be presented: d:00 (where d indicates days and 00 indicates the number of days to be delayed). 
  2. Press the + or - buttons to increase/decrease the number of days the delay should run.
  3. Once the desired number of days is displayed, move the dial back to the RUN position to activate the delay. NOTE: Number of total days depends on controller model.
