Testing Soil Moisture Sensors (biSensors)
When you test a soil moisture sensor (biSensor), the controller verifies the communication
between the controller and the biSensor and returns the following readings:
• The status of the biSensor
• The biSensor serial number
• The current soil moisture percentage value
• The soil temperature from the sensor in degrees Fahrenheit
• The two-wire voltage drop (a measure of the wire length and quality between the controller
and the biSensor)
Note: Voltage drops greater than 5 volts should be repaired.
• The version of the biSensor
1. Press the Test button. The Test menu displays.
2. Press the  or  button to highlight the Test Moisture Sensor option, and then press the OK
button. The Test Moisture Sensor screen displays.
3. Press the  or  button to select the moisture sensor number that you want to test.
4. Press the OK button to test the moisture
sensor.
Note: If any zones or programs are running
when the test is activated, watering will
pause for 10 minutes.
5. Repeat steps 3 and 4 until you have tested all
the moisture sensors that you wish to test.
6. When you have finished viewing the test results, press the RUN button to return to the Run
menu.
Refer to the following table for possible self-test statuses along with causes and suggestions for
resolving the issues.
Self-test
status
Causes/Action
No reply • Two-wire connection to the biSensor is broken – repair the wire and
connections to the biSensor.
• Two-wire voltage loss is too high – check other devices in same vicinity
for high two-wire voltage loss – repair high resistance connections
between the controller and devices.
• The biSensor is damaged – remove the biSensor and connect it directly
to the controller to test its ability to communicate.
