Introduction Soil EC Congratulations on your purchase of the Rain Bird SMRT-Y Soil Moisture Sensor kit, utilizing the the most advanced technology available on the market. You have joined those interested in conserving water, Earth’s most important resource, while optimizing the root health of your turf and trees.
Preparation Too shady Low point 1. Ensure that the property has been irrigated within the past 12 hours. This will make digging easier and lessen the likelihood of turf root damage. 2. Review each irrigation zone and identify the primary plantings (turf, shrubs, flowers, etc.). Record zone type (drip, vs. sprinkler) and where it is located on the property. For the turf zones, record whether the zone is full sun, partial sun or shade. Finally, record each zone’s current controller settings. 3.
SMRT-SMS Soil Moisture Sensor Installation Too close to walkway. Susceptable to overspray from car wash and potential foot traffic Too shady 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.
4. Using a flat bladed shovel, define three sides of a square 18” wide by 18” in length and 6” deep. This slit should be U shaped (see figure 3). Work the shovel under the sod at a depth of about 4 inches and roll back the sod leaving exposed soil 3 to 4 inches deep. About 6 inches from one side of this opening, dig a similar opening and hole to accommodate a 7” valve box. This valve box (wiring box) will be used to splice additional wire from the sensor to the zone wire identified in Step 3.
6. Within the wiring box, connect the sensor wires to the extension cable that leads to the valve box. Use grease caps for all connections after confirming proper system operation. If the extension cable wire colors do not match the wire colors from the sensor, write down the extension cable wire colors that correspond to the Red, White and Black wires from the sensor. 7.
For a weather proof connection (see Figure 6) please use: • A 7 inch round Valve Box (Rain Bird item #VB-7RND) • Grease Caps or equivalent waterproof connectors (Rain Bird direct bury connector #DBTWC25) • Use 18 AWG direct burial polyethylene insulated wire (or equivalent) for splicing and burial 8. Finally, pour a five gallon bucket of water slowly over the sensor installation area.
2. Connect the Orange wire from the SMRT-Y to one of the 24 VAC terminals on your controller. In order to determine which of the 24V terminals to connect the Orange wire to, touch the Orange wire to each of them with the controller powered on (AC adapter plugged in). Use the terminal which activates the SMRT-Y display (see Figure 8). !! NOTE: Be sure to unplug the power once you determine the correct 24V terminal. Do not disturb the power supply wires connected to these terminals.
5. Connect the Green wire from the SMRT-Y user interface to the zone terminal, where the marked zone wire was originally connected (see Figure 11). 6. 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.

Watering History The SMRT-Y user interface displays the past 7 watering attempts. If the SMRT-Y allowed watering, a drop is displayed. If the system was suspended, it will be blank. ‘Today’ indicates the most current watering cycle. The history updates 30 minutes after each cycle. Suspending Watering When the moisture in the soil is above the moisture threshold, the ‘Suspended Watering’ icon appears. Your system will not irrigate.
Calculating Field Capacity / Moisture Threshold Irrigation Run-time Guide 45% 40% 35% 30% 25% 20% 15% 10% 36% 32% 28% 24% 20% 16% 12% 8% Each lawn is different. Your Field Capacity and moisture threshold are unique. The following is the best method to determine your ideal moisture threshold setting. Remember that you can adjust your moisture threshold at any time.
System Setup 1. Set the controller to water all the zones at the highest frequency expected during the peak of the season. This may be every day. 2. Set the zone watering times as they were previously set by the contractor or homeowner. 3. Set the auto-threshold-set feature on the SMRT-Y user interface by simultaneously pressing in and holding the “Read Sensor” and “Soil Temp” buttons and then pressing the “Soil EC” button once.
Special Notes 1. This Soil Moisture Sensor is compatible with installations using pump start relays. 2. You can use this Soil Moisture Sensor with installations running multiple stations or valves simultaneously. 3. This SMRT-Y Soil Moisture Sensor can be used with a Rain Bird Rain Sensor (part number: RSDBEX). The system will operate as follows: • Connect the Rain Sensor to the sensor terminals inside your controller as directed.
Troubleshooting Symptom Possible Cause Correction The display is blank. ·· The power is not connected. ·· The controller is not plugged in. ·· Rain Sensor has been activated ·· Re-establish power to the SMRT-Y user interface by The display shows “00” ·· The sensor is disconnected. ·· Verify if Rain Sensor is activated. Review the SENSOR connecting the Orange wire to the correct 24 VAC terminal on your controller. ·· Plug in the power cord on your controller. INSTALLATION section.
