If the Rain Sensor or Freeze Sensor is preventing system operation, SENSOR OFF will be displayed on the controller’s display. Simply move the Bypass switch on the controller to BYPASS and the Solar Sync’s Rain and Freeze Sensor will be bypassed. This allows you to operate your system. The Solar Sync will continue to make adjustments to your controller’s watering schedule.
The controller’s Rain Sensor switch should be in the ACTIVE position for the Rain Sensor and Freeze Sensor to interrupt watering during rainy and/or freezing conditions.
NOTE: If you want to bypass the seasonal adjustment portion of the Solar Sync Sensor, you would need to uninstall the sensor from the controller.
