Note: It is critical that the soil is well saturated with water, otherwise the
moisture threshold calibration in Step 8 will fail. It is also important that
you complete Step 8 within one hour of saturating soil.
note
Step 7 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 “Sensor Update” button.
A numeric reading indicates success. A display of Er1 or Er2 indicates a wiring
error. Consult the Troubleshooting section on page 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 6 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 8
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 6. 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 “Er3” 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 ”Sensor Update” button for
3 seconds.
Note: All connections need to be water-tight. There are several products
on the market that will accomplish this. Follow the manufacturer’s
instructions for the product you choose.

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 8.
