1. Automatic Threshold Setting hreshold The SC6 12 controller can automatically set your sensor threshold based on your unique soil type You must first soak the sensor area to saturation with a bucket of water or hose near sundown Over night the soil will naturally drain to field capacity Early the next morning the controller will read the Field Capacity of your soil and set the sensor threshold accordingly After that you can adjust the threshold manually at any time Do this near sundown so the sun will not affect the natural draining of the soil by causing additional evaporation or Transpiration Press the and buttons simultaneously while editing the sensor threshold to activate the automatic sensor setup The Setting Sensor Threshold indicator will be displayed while the controller is determining the threshold To cancel the action press the and buttons simultaneously Early the next morning the SC6 12 will automatically determine your soil s field capacity and set up the sensor threshold accordingly NOTE Do not allow the sensor zones to water in timed mode during the night while the controller is automatically setting the threshold Set the zone to sensor mode or set the run start time to OFF You always have the option to edit the sensor s moisture threshold or automatically set it at anytime Repeat process for each sensor on your system SC6 12 User Manual Page 17 Service and Warranty Troubleshooing Symptom The display2.
