SMRT-Y Soil Moisture Sensor
Optional wiring for Xeriscape or flower beds
You may have zones you wish to water regardless of the moisture level measured by your sensor. For example,
a flower bed drip or a desert landscaping zone. The SMRT-Y can accommodate up to two such zones.
How to connect them:
1.
Identify the zone(s) that fit into this category. Note which terminal(s) they are connected to on your
controller.
2.
Loosen the screw that connects such zone wire to your controller.
3.
Strip the wires and connect the Blue wire from the SMRT-Y user interface to the same terminal as the
zone wire.
!
NOTE:
There will now be two wires connected to this terminal; a Blue wire going to the SMRT-Y
user interface and a zone wire going to the valve.
4.
If you have a second zone to run independently of the moisture sensor, connect the Brown wire
from the SMRT-Y user interface to the second terminal. Now these two zones will run independent of
moisture sensor.
5.
Turn on the controller and allow the SMRT-Y user interface to take a soil moisture reading. The reading
should appear in the display after 4-5 seconds. If the reading is zero the wiring to the sensor is not
correct and will need to be reviewed and corrected. If the reading is not zero, the wiring is correct and
you may finish up the grease cap installation on the sensor wiring.
