Note: It is critical that the soil is well saturated with water, otherwise the
moisture threshold calibration in Step 7 will fail. It is also important that you
complete Step 7 within one hour of saturating soil.

note
Note: If the biSensor receives water during this 24 hour period, or was not
saturated during Step 6, the calibration will either fail entirely or set an
incorrect threshold for your lawn. If this happens, you will need to
resaturate the soil and restart Step 7.
Step 6
Verify All Connections
Reconnect biSensor to desired valve. Verify that all connections are functioning properly after
the biSensor has been buried.
1. Verify communications with biSensor by pressing the “Read / Set” button. A numeric
reading indicates success. A display of Er1 or Er2 indicates a wiring error. Consult the
Troubleshooting section on pgs 11-12 If you receive an error.
2. If the numeric reading is below 20, the biSensor has excessive air pockets around it. If
this occurs, rebury the biSensor as per Step 5 taking extra care to ensure the soil is well
compacted around the biSensor.
3. Manually run the station connected to the biSensor. This will verify connection.
Step 7
24 Hour Moisture Threshold Calibration
The S100 comes with an auto-calibration capability that will set the moisture threshold
based on your soil type. This is useful for new installations. Before running the moisture
threshold calibration; ensure that the soil around the biSensor is heavily saturated with
water as instructed in Step 5. If not properly saturated, the calibration will fail. Write down
the current date, time and sensor reading to be used as a reference point.

1. Hold the (+)(-) and (Bypass) buttons simultaneously for 3 seconds. The screen will flash
between “CAL” “24H” and the current moisture reading. The “24H” will count down on
the hour until the calibration is complete. Watering is paused during this time. It is
important that the biSensor does not receive any water during calibration. This process
will fail or provide false feedback if it does.
2. If the calibration succeeds, the moisture threshold will be automatically set, and the
system will allow watering when soil moisture drops below this threshold.
If an error occurs during calibration, the screen will flash “Er4” indicating calibration failed,
and then another “Er#”. This # represents the reason for failure. See Troubleshooting for
information on the various error messages. The S100 will need to be re-calibrated. In addition,
in the event of a failure, the S100 will go into “bypass” mode allowing for normal timer-based
watering
Note: If you need to exit this mode early, hold the (Read / Set) button for 3 seconds.
Note: All connections need to be submersible. DBY or equivalent on the valve
side is recommended. There are several products on the market that will
accomplish this. Follow the manufacturer’s instructions for the product you
choose.
