Soil Sensor System

User’s Guide

Introduction

Leveraging the same Toro soil-sensing technology used on high-end commercial sites and world-class golf courses, the Toro Precision™ Soil Sensor continuously monitors the soil moisture and determines when

watering is actually needed – greatly increasing the efciency of your

sprinkler, reducing wasteful over-watering, while promoting the overall health and beauty of your landscape.

The Precision Soil Sensor system consists of a wireless soil moisture sensor and digital receiver, making installation quick and simple. The compact receiver installs alongside the timer, either indoors or out, and connects directly to the timer’s power and sensor terminals, or simply taps into the valve common wire circuit. The sensor is placed in a suitable lawn area where it sends soil moisture and air temperature readings to the receiver every 10 minutes. When automatic watering is scheduled to start, the Precision Soil Sensor allows the sprinklers to run only if the soil moisture has dropped below the minimum moisture setting, and the air temperature is favorable for watering.

The sensor simply plugs into the soil – there are no holes to dig or wires to bury. All you’ll need to complete the installation is a small Phillips screwdriver, three AA alkaline batteries and a bit of do-it-yourself enthusiasm.

The Precision Soil Sensor system is designed to help grow and maintain healthy landscape vegetation while reducing water use by improving the operation of your sprinkler control timer. It cannot improve or remedy a sprinkler system that’s improperly designed, installed or maintained. To gain the maximum benefit afforded by the addition of the Precision Soil Sensor, it is important to make certain your automatic sprinkler system is in good working order; capable of providing proper sprinkler coverage–where and when it’s needed.

hinged cover).

• The receiver can be installed indoors using the mounting tape provided. For outdoor installation, attach the receiver using the two stainless steel screws provided.

• When installed outdoors, the receiver cover should remain closed when access is not required.

1. Drive the top mounting screw into the wall, leaving about 1/8” from flush.

2. Place the receiver on the screw using the keyhole slot.

3. Install and tighten the lower mounting screw.

4. Route the connection cable through the bottom of the timer, into the wire connection area.

Connect Receiver to Timer

Note: If the timer is equipped with sensor terminals, continue at Step 1 below.

If the timer is not equipped with sensor terminals, continue at Step 1a. Refer to your timer’s user guide for specific information regarding sensor installation and Sensor control switch operation.

Note: When the receiver is connected to the timer’s sensor terminals, Rain Hold

will be indicated when the Precision Soil Sensor is actively restricting irrigation.

The Precision Soil Sensor does not replace or function as a Rain Sensor.

Caution: Ensure the timer’s power source is disconnected prior to con-

necting the receiver wires.

Setup for Timer With Sensor

1. Locate the Sensor connec-

tion terminals. If the timer has (or requires) a jumper wire on the Sensor terminals connect the receiver for Normally Closed (NC) operation. If a jumper wire is not required, connect the receiver for Normally

Open (NO) operation.

2. For a Normally Closed Sensor:

Remove the jumper wire, and connect the Brown and White wires to

the Sensor terminals (in either position). The Yellow wire is not used. For a Normally Open Sensor: Connect the Yellow and White wires to the sensor terminals (in either

position). The Brown wire is not used.

3. Continue to Step 4 below. Setup for Timer Without Sensor 1a. Remove the wire(s) connected

to the field Common terminal (labeled COM or C).

2a. Using a twist-on wire connec-

tor, attach the Brown wire to the wire(s) removed from the Common terminal. The Yellow

wire is not used.

3a. Attach the White wire to the

Common (COM) terminal.

Common Setup (continued)

4. Attach the Red wires to the timer’s 24 VAC power terminals.

Caution: The receiver requires a source of 24 VAC continuous power

for operation. Severe damage will result if wired directly to 110/120 VAC.

5. Apply power to the timer.

Note: When the receiver is initially powered

up, the green LED will light, and the display will

show two bars with alternating Signal and

Battery symbols.

Adjust Watering Program

Review the timer’s automatic watering program and adjust as necessary to provide the following watering schedule:

• Set watering to run every day of the week – with the exception of restricted

watering days.

• Set a run time duration for each zone that will provide thorough watering

– without causing pooling or runo.

• Ensure an automatic watering cycle will run within 16 hours after initial

installation of the Precision Soil Sensor.

Select the Sensor Installation Site

Choosing the right location for the sensor is very important for the overall eectiveness of the Precision Soil Sensor system.

The illustration below represents a typical residential landscape. The blue sections indicate the areas that will receive the most direct sunlight throughout the day may be considered for sensor placement.

From among the prospective lawn areas, select an installation site with the following characteristics

• Is representative of the overall soil type and condition

• Is the highest elevation

• Is not over a septic tank or drain eld

• Is well within receiver communication range (500’ line-of-sight)

• Is at least 4 feet away from a driveway, roof overhang or downspout

• Is not in a footpath or recreational area

• Is not exposed to overspray from nearby watering zones

Install Sensor Batteries

• Remove four stainless Phillips screws securing the sensor battery compartment cover. Place cover aside.

Note: The sensor requires three size

AA alkaline batteries for operation. Batteries are not included.

• Install the batteries as shown.

• Install the battery compartment cover.

Note: When the sensor batteries are initially installed, the LED signal indica-

tor is Red. When the receiver links with the sensor, the LED changes to Green. The LED will remain on for 30 minutes to facilitate sensor installation.

Install Sensor

1. Move the sensor to the proposed installation site. Signal strength is

indicated by the LED color as follows:

Green = Excellent Yellow = Acceptable Red = Not Acceptable - Relocate Sensor

2. Thoroughly irrigate the sensor location and surrounding landscape area. This step is

crucial to establish the “100%” moisture level for sensor calibration.

3. Trim the grass close to ground level where the sensor will be placed.

Caution: For close-cut turf varieties,

such as Hybrid Bermuda, the top of the sensor must be installed at grade level to prevent damage by mowing equipment.

4. Applying even, downward pressure on top of the sensor, insert the sensor probes and retention spikes completely into the soil.

5. At the receiver, press the Bypass to begin sensor calibration and place the Precision Soil Sensor in the Normal Operating mode (page 6).

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 watering 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 o. When switched on, the Bypass mode will be automatically 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-o Mode

If the sensor detects that air temperature has dropped to near freezing, the Precision Soil Sensor automatically switches to the Freeze Shut-o mode to restrict watering. When the temperature rises, the Freeze Shut-o 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.

System Status Indications

Warning Mode Indication

If the sensor does not communicate with receiver within a 24-hour period, the Precision Soil Sensor switches to the Warning mode, indicated by all three LEDs blinking continuously. Watering will be permitted until the loss of communication has been corrected.

Restoring Operation

Loss of communication can be caused by a damaged sensor, relocating the sensor to a dierent area of the yard, or a temporary obstruction, such as a car or truck parked in the signal path. The most likely cause, however, is the sensor batteries have become too weak to provide adequate signal strength.

If the sensor appearance and location is unchanged, and the signal path is unobstructed, replace the sensor batteries with three new AA alkaline batteries. Press the Bypass button to cancel the Warning mode. If communication is reestablished, the Precision Soil Sensor will automatically resume normal operating mode within a short time.

Note: If the above measures do not restore normal operation, contact Toro

Customer Service for assistance at 1-877-345-8676.

Battery and Signal Strength Indications

The receiver display provides current battery and signal strength status during all normal operating modes. The number of stacked bars that appear with the corresponding antenna and battery display symbols, indicate the current conditions as shown in the chart below.

Signal Battery

6 Bars = Excellent 6 Bars = Excellent

4 Bars = Acceptable 4 Bars = Acceptable

2 Bars = Weak - Check Sensor 2 Bars = Weak - Replace Batteries

Landscape plants are the heartiest when their roots become established several inches down where water is stored for the longest period of time. Watering often, for short periods of time, promotes root growth near the top of the soil, where the moisture evaporates quickly.

The key to maintaining healthy plants with minimum water waste is to water thoroughly–only when it’s needed.

The Precision Soil Sensor is preset to restrict watering until the soil moisture level drops to 50% of soil capacity, or 1/2 of the total moisture that can be retained in the soil. If you were to draw a comparison to a car’s fuel tank, 50% of the soil moisture capacity would be similar to using 1/2 of the fuel in the tank before stopping to rell. A 50% setting restricts the sprinklers from relling the soil to capacity until 1/2 of the moisture has been lost, causing the roots to go deeper for water. With the capability to adjust the setting incrementally from 0% to 100%, the Precision Soil Sensor can be ne-tuned for virtually any soil condition.

Fine-tuning the Moisture Level

Changes to the 50% setting should be made initially in 5% increments in order to see results within a few days. The objective is to nd the moisture setting that results in a mild stress condition in the lawn, indicated by slight wilting and dryness. At that point, adjust the setting 5% in the opposite direction. This should result in moisture maintenance level that’s very close to optimum.

• Press and release the Plus button to display

the current setting (50 % by default).

• Press the Plus button to increase, or the Minus

button to decrease the setting.

• Press Menu button to return to the Normal

Operating mode.

System Calibration Mode

Automatic calibration of the sensor occurs within 24–48 hours after initial installation. Calibration is required to establish the maximum amount of usable moisture in the soil. The sensor system will then recognize this soil moisture level as the maximum capacity (100%). From this xed reference point, the sensor system can decide when the soil moisture has dropped enough (50% by default) to allow watering. Manual calibration of the sensor can be performed at any time if, for example, the sensor has been moved to a dierent location in the landscape or has been replaced since initial installation.

Use the following procedure:

1. Run an automatic or manual watering operation to thoroughly irrigate the sensor zone.

2. Wait for 2 to 4 hours for the water to be absorbed.

Note: The objective is to apply as much water

as possible to the sensor zone – up to the point of runo, then allow the soil drain down 2 to 4 hours to establish the maximum moistureretention capacity (the 100% mark).

3. Press the Menu button to display CA (system calibration mode).

4. Press the Minus button to display 00.

5. Press and hold the Plus button (several seconds) until the Green LED indicator and hourglass symbol begins ashing. The receiver’s Red LED will be on.

6. The new calibrated moisture % value will be displayed automatically within 10 minutes.

Sensor Learn Mode

The Precision Soil Sensor receiver has been paired (matched) at the factory to a unique sensor identication code, to prevent communication with other sensors that may be installed within reception range. If either the receiver or sensor is replaced, the frequency pairing procedure is required to enable wireless communication. The receiver Learn mode is provided to accomplish the pairing procedure.

To pair the receiver to the sensor, use the following procedure:

•

Press and hold the Bypass button (without releasing) until the receiver switches to the Learn mode and the display shows LE. The Green LED will turn on, and the Red and Yellow LEDs will begin blinking.

• If the sensor is operational (batteries installed), paring will occur automatically the next time a signal is sent from the sensor (within 10 minutes). The receiver will automatically return to the Normal Operating mode when communication is established.

• If the sensor batteries have not been installed, automatic pairing will occur upon battery installation. Press the Bypass button to return to the Normal Operating mode.

Solving Reception Problems

The Precision Soil Sensor system operates under Part 15 of the FCC rules. This means that it has to comply with certain standards and is only allowed to transmit up to a certain power level. In rating transmitters of any form, typically a Line-of-Sight (LOS) value is used to show the relative eectiveness of a transmitter and allow a transmitter and receiver to be compared to one another using a fair (apples to apples) method. The Precision Soil Sensor has an eective operating range up to 500 feet LOS

- meaning in an open eld, with no obstructions, the system will have a successfully communication range of up to 500 feet. However, in almost all installations, there are obstacles between the sensor and receiver such as walls, oors, etc. These obstacles will aect the signal reception and typically reduce the radiated signal strength sent to the receiver. Dierent objects aect the transmitted signal dierently depending on the construction material, geometry, and size. Typically, most residential construction materials do not reduce the eective transmitted signal enough to pose problems under normal installation conditions. However there are some indoor installations with very thick walls, or where radio frequency interference is high due to a nearby pump motor or large electrical appliance.

To help resolve wireless communication problems:

• Install the sensor as close to the receiver location as possible to reduce the potential for interference and signal reduction. If the signal strength is not good in one location, try another appropriate location nearby - just moving the sensor a few feet can greatly improve signal strength.

• Interior locations where cell phones or cordless phones have trouble with reception may indicate areas with poor RF signal transmission. The receiver can be installed outdoors and connected to the timer with extended wire leads.

Moisture Reading “-0.1”

It is possible for the receiver to display a moisture level of “-0.1”. This may occur for several reasons:

1. Very low moisture at the sensor.

2. Sensor not calibrated properly for the location so low moisture responds with an extremely low reading.

3. Sensor not reading correctly (defective).

Check the ground moisture near the sensor and recalibrate if needed to see if the reading comes back up.

Installing a Rain Sensor with a Soil Sensor

It is possible to connect both a rain sensor receiver and a Soil Sensor receiver to a controller’s sensor port. The beige and white wires from the soil sensor receiver and rain sensor receiver must form a circuit, as diagrammed.

As in, the beige wire from one receiver and the white wire from the other receiver connect to the controller’s sensor port, and the remaining beige and white wires are attached together with a wire nut.
