Baseline Systems WaterTec S100 - Manual (Page 18)

Note: Moving the threshold more than 0.2 in every 3 water cycles can cause
erratic behavior. If your lawn is very dry, run a few extra cycles in order to
catch up.

Troubleshooting Error Codes
Er1: Communication Error
● Incorrect Wiring.
● Bad Connections.
● Damaged Wire.
Er2: Over Current
● Bad Valve Solenoid.
● Short Circuit Wires.
Er3: Damaged biSensor
● Shown if the biSensor stick is damaged.
Er4: 24-hour Moisture Threshold Calibration Failed
● This error is accompanied by one of the other five error codes to indicate reason for failure.
Er5: Value Out of Range Warning
● This warning can occur only during 24-hour moisture threshold calibration, and indicates that
the biSensor readings fall outside of the expected range. This could be caused by failure to
saturate the soil with water in the beginning, or by accidental watering of the site after
calibration started. If an Er4 occurs the S100 will determine the best possible moisture threshold
based on the measured moisture values and allow the sprinkler system to water based upon this
setting.
Er6: Low Reading During 24-hour Moisture Threshold Calibration Error
● This error can occur only during 24-hour moisture threshold calibration and indicates that there
was a low reading during calibration. To resolve this, follow the instructions under Step
5 on page 16.
Step 7: Changing the Moisture Threshold
The S100 Moisture Threshold calibration calculates a threshold for an average system. If
the distribution uniformity at your site is above or below average it may be necessary to
adjust the threshold for fine tuning. It may also be necessary once the roots have grown
around the biSensor.
● While the “Read / Set” button is being held, use (+)/(-) buttons to change the
moisture threshold.
● Raising the threshold will result in more frequent watering.
● Lowering the threshold will result in less frequent watering.
