System Operating Modes
Note:
If installation of the Precision Soil Sensor system has not been completed
or the system is not yet operational, refer to System Installation and Setup
procedures beginning on page 4.
Normal Operating Modes
Watering Permitted
When the Precision Soil Sensor is in the
Watering Permitted mode, the current soil
moisture % value is displayed, and the Green
LED is on. In this example, the current soil
moisture level is 42%, which is below the *50%
soil moisture maintenance level, and watering
is allowed.
Watering Restricted
When the soil moisture is above the *50% soil
moisture maintenance level, the Precision Soil
Sensor switches to the Watering Restricted
mode. A delay period of *4 hours begins
counting down before watering is actually
shut off. The delay period allows any
remaining sprinkler zones in the water-
ing cycle to finish. The display will toggle
between displaying the current soil moisture
% value and the amount of time remaining in
the current watering cycle completion period.
In this example, the moisture level is 96%, and
the Green LED is on since watering will be
allowed to continue for 4 hours. The Watering
Restricted mode will begin immediately
following the watering cycle completion period. While in the Watering
Restricted mode, the current soil moisture % value with the No Watering
symbol will be displayed, and the Red LED will remain on.
Note:
Ideally, one watering cycle should replenish the moisture level to 100%.
Watering program changes may be required to achieve this condition. Refer to
your control timer user's guide for information regarding programming options.

*Note:
A value shown with an asterisk (*) indicates that it is the factory default
setting within an adjustable range. Refer to Advanced System Operations Menu
beginning on page 6 for detailed information regarding system settings and
adjustment options.
Smart Bypass Mode
The Smart Bypass feature enables the
sprinkler system to operate while the Precision
Soil Sensor is in the Watering Restricted mode.
Pressing the Bypass
button toggles
the Smart Bypass feature on and off. When
switched on, the Bypass mode will be auto-
matically canceled in *24 hours or it can be
manually canceled at any time.
While the Precision Soil Sensor is in the Smart
Bypass mode, the Green LED will be on and
the Yellow LED will blink continuously. The
display will toggle between the current soil
moisture % value and the amount of time
remaining until the Watering Restricted mode
resumes. In this example the moisture level
is 85% and the Green LED is on. There are 24
hours remaining in the Smart Bypass mode.
Freeze Shut-off Mode
If the sensor detects that air temperature has dropped to near freezing, the
Precision Soil Sensor automatically switches to the Freeze Shut-off mode
to restrict watering. When the temperature rises, the Freeze Shut-off mode
is canceled. Normal Operation mode will resume after the delay period set
by the Smart Bypass Timer.
In this example, air temperature is detected
at the minimum setting of *39°F and watering
has been canceled. The Freeze temperature
and No Watering
symbols are displayed,
and the Red LED will blink continuously.
