Fine-tuning the "Low Threshold" Moisture Level
Changes to the 50% setting should be made initially in 5%
increments in order to see results within a few days. The
objective is to find the moisture setting that results in a mild
stress condition in the lawn, indicated by slight wilting and
dryness. At that point, adjust the setting 5% in the opposite
direction. This should result in moisture maintenance level
that's very close to optimum.
1. Press or to increase or decrease the Low
Threshold point by 1%.
2. Press to input the desired value.

SIGNAL STRENGTH

Indicates signal strength as a series of bars ( ).

BATTERY LEVEL

Indicates the battery strength in the soil sensor.

CALIBRATE

Calibration is required to establish the maximum amount of
usable moisture in the soil. The sensor will then recognize this soil
moisture level as the maximum capacity (100%). From this fixed
reference point, the sensor determines when the soil moisture has
dropped enough (to the "Low Threshold") to allow watering.
Manual calibration: At some point, it might be necessary to
recalibrate the sensor (in the event of a sensor relocation for
example).
1. Run an automatic or manual watering operation to
thoroughly irrigate the sensor zone.
2. Go to the Sensor Menu of the soil sensor to calibrate.

CAL SETTING

3. Press to
to the number field. Use
calibration number (default 5: approximately a 1-day
"watch window"). Press

CAL SETTING
The "Cal Setting" number adjusts the time it takes to
calibrate the sensor. A Cal Setting of '0' calibrates the
sensor to the current moisture level in the ground. The
calibration will be set using the next sensor reading
(within 30 minutes).
Additional calibration settings are available. From '1' (~1
day "watch window") to '168' (~7 day "watch window").
