SMRT-Y Soil Moisture Sensor
SMRT-SMS Soil Moisture Sensor Installation
1.
Manually turn on the zone where the sensor is to be installed and the adjacent zones. Observe the
water distribution patterns and select the sensor installation spot.
!
NOTE:
Avoid placing the sensor where water will accumulate from runoff such as near driveways,
sidewalks, depressions and at the base of berms or hills.
2.
Pick a spot where the turf is healthy and the subsoil allows drainage. Place the sensor at least 4 feet
away from sprinkler heads and in an area that is irrigated by only the one selected zone.
3.
Locate the nearest valve box to the chosen sensor installation spot. Identify and mark both ends of a
zone wire in the valve box and at the controller. You can do this by manually bleeding a valve in the
valve box to find out what zone it controls. Place a piece of electrical tape on the zone wire connected
to that valve. Then place a piece of electrical tape on the other end of that wire in the controller box.
Make sure that the selected wire is the zone wire and not the ‘common’ wire.
!
NOTE:
Avoid selecting a zone which powers more than one solenoid. The green wire from the
SMRT-Y user interface must be connected to a zone which activates a single valve solenoid.
