4. Press ENTR to test the biSensor. This test will return the current moisture, soil
temperature, and two-wire voltage drop.
Self-test status Cause/Action
No response

Two-wire connection to the biSensor is broken – repair 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 controller and devices.

The biSensor is damaged – remove biSensor and move it
directly to the controller to test its ability to communicate.
Zero Reading

The biSensor detection blade is damaged – if the soil
temperature reading is valid replace the biSensor.
There are additional categories of biSensor conditions that are a result of biSensor placement or
programming that are covered in the following table. These conditions are only valid where the
biSensor is buried.
Condition Causes/Action
Ground is too dry
with low biSensor
moisture reading

Not enough zone water time – increase water time to apply
at least 0.5” of water

biSensor not being watered by its primary zone – change
assignment or move biSensor to correct location

Program start times are too infrequent – increase the
program start time frequency

biSensor limit is too low – raise limit or run a biSensor
calibration cycle (refer to page 38)
Ground is too dry
with high biSensor
moisture reading

biSensor not being watered by its primary zone – change
assignment or move biSensor to correct location

biSensor is buried too deep – rebury biSensor to be only 3”
deep
Ground is too wet
with high biSensor
moisture reading

biSensor is buried in low area where water collects – move
biSensor from low area

biSensor not being watered by its primary zone – change
assignment or move biSensor to correct location

Program start times are too often – increase the interval
between start times

biSensor limit is too high – lower limit or run a biSensor
calibration cycle (refer to page 38)
