Step 1 bisensor Placement When planning the bisensor location, take into account variables such as sprinkler patterns, distribution uniformity, sun exposure and soil type, or other site specific characteristics that may affect water holding capacity or the rate at which plants use water. The location of the bisensor will determine how frequently your sprinkler system is allowed to water. If the bisensor is placed in an area that is generally wetter than average it will cause your system to operate less frequently, possibly causing dry spots. If the bisensor is placed in an area that receives less than average water it will cause the system to operate more frequently. Baseline bisensor placement recommendations Place the bisensor midway between two heads (should only receive water from one zone). Place the bisensor in an area that receives average to slightly below average water. Keep away from sidewalks and driveways to avoid water from car washing or other factors. The illustration to the right identifies heavy shadow and runoff areas in Red and ideal locations in Light Green. Avoid Red areas when installing your bisensor. Dark green areas with some shadow can be used as a secondary location. SENSOR LOCATION SECONDARY LOCATION SENSOR LOCATION SENSOR LOCATION SECONDARY LOCATION SENSOR LOCATION N note Note: When installing the bisensor connect it to the most convenient valve. This connection is used for communication. WaterTec S100 Manual June08 5

Step 2 Install and Wire S100 Valve Common Interrupter Black wire connects to the clock common. Orange wire connects to one side of the 24 VAC going into the clock. Test each to find the one that supplies power. White wire connects to the field common. Green wire connects to the zone (on the clock) that the sensor is wired across. Red wire connects to the sensor and valve in the field. Brown and Blue wires can be connected to a zone to bypass S100 based watering, if needed. Only one zone per wire is allowed. These zones will operate solely based on the sprinkler timers configuration, without any input from the S100. In the example below, the blue wire from the S100 is connected to Zone 1 on the sprinkler timer. As a result, Zone 1 will bypass sensor control and watering for Zone 1 will be based soley on the sprinkler timers configuration.

MADE IN USA Step 3 Setup Sprinkler Controller and Set Cycle Window 1. Set your sprinkler controller to apply 1/2 to 3/4 of water to each zone each day. This will allow the in-ground moisture bisensor to choose the best possible days to water. For instructions on how to check distribution rate, see STEP 2 on page 15 of the Troubleshooting section. (If needed, refer to the sprinkler timer s manual for operational instructions). tertec 100 TM oil Moisture READ / SET BYPASS % * Soil Moisture Sensor BUSY DRY / ALLOW + WETTER Moisture Threshold/ Cycle Window DRYER - SPRINKLER TIMER 24V COM 1 2 3 4 2. The cycle window is the time allowed to complete a watering cycle once the first zone has started watering. The S100 comes preset with a 12 hour window. Adjust this value to be at least one hour more than your complete cycle time. Reasons to re-set the cycle window: If your system needs more than twelve hours to complete a watering cycle once the cycle has started. If you choose to water your lawn several times per day (this can result in poor root development). To set the cycle window hold the Bypass button for 2 seconds. This will display the current cycle window. Use (+)/(-) buttons while holding the Bypass button to change the cycle window to a value between 0 and 24 hours. When the cycle window is finished, and the moisture is still below the threshold, the cycle window will start again if a valve is running. It is important the cycle window is set to fit all watering needs plus an additional hour for padding. Step 4 Connect the bisensor NOTE: It is very important that you use waterproof connectors after all connections have been verified in Step 7. 1. Before burying the bisensor, verify communications by pressing the Read / Set button. A numeric reading indicates success. A display of Er1 or Er2 indicates a wiring error. Consult the Troubleshooting section on pages 11-12. 2. Manually run the station to which you connected the bisensor to verify connection. 3. Once connections have been verified, disconnect the bisensor from the valve as this simplifies burial. WaterTec S100 Manual June08 7

Step 5 bisensor Installation The bisensor has several burial requirements. There must be good contact between the soil and the bisensor, and it needs to be buried lying on its side. If buried flat, the bisensor readings can be wrong due to moisture pooling on the surface of the bisensor. The bisensor is buried 2 to 3 inches deep in turf areas and deeper for planters and tree areas (root zones). Wet the ground thoroughly before beginning either Option below. OPTION A Dig 6 X12 section and...... peel back sod with roots intact. note Note: Ensure bisensor is buried 2-3 below grass line for optimal readings. This depth also prevents future damage, i.e., aerators, etc. (Option A) - Works well for rocky soils 1. Using a shovel or edger cut out a piece of sod approximately 1-foot long by 6-inches wide in the area where you plan to bury the bisensor. 2. Carefully remove the sod and try to keep the roots intact. 3. Dig a small trench the length of the bisensor in the exposed dirt. 4. Insert the bisensor into trench, burying it on its long edge. If buried flat, bisensor readings can be wrong due to moisture pooling on surface of the bisensor. 5. Remove any rocks or gravel that are touching the surface of the bisensor to ensure there are no air pockets. 6. Cut a slit back to the valve box for the communication wires. Take care to bury them deep enough to avoid damage from aeration or other activities. 7. Using a bucket of water saturate the soil surrounding the bisensor and compact the soil around it tightly. 8. Refill hole, replace sod and saturate the area thoroughly. Once saturated, compact soil firmly around the bisensor. The bisensor must make good contact with the surrounding soil. Bury bisensor 2 4 TO 6 3 deep Re-cover area and heavily saturate with water. OPTION B Cut slit into grass about 12 long by 6 deep... then work shovel back and forth to create a a slot for the bisensor Bury bisensor 2 4 TO 6 3 deep (Option B) - Works well for sandy or loamy soils 1. With a flat blade shovel, cut a slit in the grass where the bisensor will be placed. Widen slit with a back and forth motion. 2. Place the bisensor in the slit horizontally so the top of the bisensor is 2-3 deep. Re-cover area and heavily saturate with water. 3. Remove any rocks or gravel that are touching the bisensor to ensure there are no air pockets. 4. Cut a slit back to the valve box for the communication wires. Take care to bury them deep enough to avoid damage from aeration or other activities. 5. Using a bucket of water saturate the soil surrounding the bisensor and compact the soil around it tightly. 8 WaterTec S100 Manual June08

note Note: It is critical that the soil is well saturated with water, otherwise the moisture threshold calibration in Step 7 will fail. It is also important that you complete Step 7 within one hour of saturating soil. Step 6 Verify All Connections Reconnect bisensor to desired valve. Verify that all connections are functioning properly after the bisensor has been buried. 1. Verify communications with bisensor by pressing the Read / Set button. A numeric reading indicates success. A display of Er1 or Er2 indicates a wiring error. Consult the Troubleshooting section on pgs 11-12 If you receive an error. 2. If the numeric reading is below 20, the bisensor has excessive air pockets around it. If this occurs, rebury the bisensor as per Step 5 taking extra care to ensure the soil is well compacted around the bisensor. 3. Manually run the station connected to the bisensor. This will verify connection. note Note: All connections need to be submersible. DBY or equivalent on the valve side is recommended. There are several products on the market that will accomplish this. Follow the manufacturer s instructions for the product you choose. Step 7 24 Hour Moisture Threshold Calibration The S100 comes with an auto-calibration capability that will set the moisture threshold based on your soil type. This is useful for new installations. Before running the moisture threshold calibration; ensure that the soil around the bisensor is heavily saturated with water as instructed in Step 5. If not properly saturated, the calibration will fail. Write down the current date, time and sensor reading to be used as a reference point. Date Time Sensor Reading 1. Hold the (+)(-) and (Bypass) buttons simultaneously for 3 seconds. The screen will flash between CAL 24H and the current moisture reading. The 24H will count down on the hour until the calibration is complete. Watering is paused during this time. It is important that the bisensor does not receive any water during calibration. This process will fail or provide false feedback if it does. 2. If the calibration succeeds, the moisture threshold will be automatically set, and the system will allow watering when soil moisture drops below this threshold. If an error occurs during calibration, the screen will flash Er4 indicating calibration failed, and then another Er#. This # represents the reason for failure. See Troubleshooting for information on the various error messages. The S100 will need to be re-calibrated. In addition, in the event of a failure, the S100 will go into bypass mode allowing for normal timer-based watering Note: If you need to exit this mode early, hold the (Read / Set) button for 3 seconds. note Note: If the bisensor receives water during this 24 hour period, or was not saturated during Step 6, the calibration will either fail entirely or set an incorrect threshold for your lawn. If this happens, you will need to resaturate the soil and restart Step 7. WaterTec S100 Manual June08 9

Future Adjustments Manual Threshold Adjustment: As the grass roots grow back around the bisensor, the threshold may need to be adjusted. Observe lawn conditions and then adjust the threshold as needed. To manually adjust your moisture threshold begin by taking a bisensor reading (after a watering cycle) by pressing the Read / Set button. Next set your threshold slightly above or below this value (an adjustment of 0.5-1.0 points is all that should be necessary). Raising the threshold will result in more frequent watering. Lowering the threshold will result in less frequent watering. Automatic Moisture Threshold Calibration: If you need to re-calibrate your moisture threshold, simply begin by re-saturating the ground surrounding the bisensor. The dirt surrounding the bisensor needs to be holding as much water as it can, it may take a few applications of water to accomplish this. Once saturated, repeat Step 7 of this manual to calibrate your moisture threshold. Manual Run: Before you run a zone manually, press the Bypass button on the S100. This will prevent a cycle window from starting. Press the Bypass button again once your manual cycle is over. How to Get a Beautiful Lawn Watering SMART is a critical step towards a beautiful and healthy lawn. Water Less Frequently Using the S100 to determine which days to water will promote deep roots and will water only when needed, conserving water (and saving you money). Watering too often promotes a shallow root structure and washes nutrients from the roots. Water Deeply Set your sprinkler timer to apply 1/2 to 3/4 of water (determine water application rate for each zone and calculate the run time to apply 3/4 of water use cups or cans to catch water for a fixed time to determine application rate). Each zone could have a different water run time. 10 WaterTec S100 Manual June08

Adjust the run time accordingly Refer to Step 7 on page 17 Refer to Step 3 on page 15 Make sure the bisensor is placed within an area that follows the guidelines on page 5. If it does, check to see if the bisensor is receiving any water from an alternative source (An example being your neighbors sprinklers) bisensor is receiving adequate water, other areas are wet Zones 1, 3 and 4 are receiving adequate water. Zone 2 has dry or wet areas Water distribution is not uniform bisensor is buried in an area that receives significantlly below average watering Water distribution in zone 2 is not uniform Refer to Step 3 on page 15 Make sure the bisensor is placed within an area that follows the guidelines on page 5. If it does, check to see if the bisensor is not receiving any water due to an obstruction (For example a bush obstructing a sprinkler head) Refer to Step 3 on page 15 14 WaterTec S100 Manual June08

Step 1: Verify bisensor Communication 1) Push the Read / Set button to verify communication. A numeric value should appear. If an Er# appears refer to the Troubleshooting section on pages 11-12. 2) Run a Communication Test: Hold (+)(-) and (Read / Set) buttons simultaneously for 3 seconds. This test will flash alternately between SEn and ###. ### will start at 100 then count down to 0, repeatedly communicating with the bisensor. This process takes about two minutes. 3) When it finishes it will flash Err and a number which is the quantity of errors it encountered in its attempts, 000 to 100. This number is not the error type. This error count will stop displaying after 10 minutes. Note: To exit this mode early press and hold the Read / Set button for 3 seconds. 4) A reading of 000 is good, meaning there are no errors. A reading above 000 means that the sensor encountered problems while communicating with the S100. 5) If an error is encountered in this step, it is either an Er1 or Er2. If more than 2 errors were encountered in this way, refer to the top of the Troubleshooting section for specific information. 6) Repair wires or connections. Also be sure that the maximum wire distances aren t exceeded. 7) Repeat Step 1. Step 2: Check Application Rate by Zone To check the application rate of your system use several flat bottom containers placed randomly throughout the zone (tuna cans work well). Run the zone for a period of time long enough to get a measurable amount of water in each catch device. Use the formula below to calculate the new runtime. Average amount in cans (inches) Desired amount applied (inches) x Time that zone operated during test (minutes)= New runtime (minutes) Step 3: Check Distribution Uniformity by Zone To check the distribution uniformity of your system use several flat bottom containers placed randomly throughout the zone. Run the zone for a period of time long enough to get a measurable amount of water in each catch device. Compare the amounts in each device. Using this information, make adjustments to the sprinkler system in order to get a more uniform water distribution. Step 4: Check Distribution Uniformity and Application Rate in the bisensor Zone To check the application rate of the zone the bisensor is buried in, use several flat bottom containers placed randomly throughout the zone (tuna cans work well) making sure at least one catch device is placed directly above the bisensor. Run the zone for a period of time long enough to get a measurable amount of water in each catch device. Use this information to determine the following: The bisensor is placed in an area receiving average to slightly below average precipitation within the zone. This is an optimal location for the bisensor. The bisensor is placed in an area that is generally wetter than average. This will cause your system to operate less frequently, possibly causing dry spots. WaterTec S100 Manual June08 15

Step 4: Continued The bisensor is placed in an area that receives far less than average water. This will cause the system to operate more frequently then desired. If it is determined that the bisensor is not receiving an average to slightly below average amount of water check the performance of all the related system components: - Check all sprinkler heads affecting the area to ensure they are functioning properly. - Check the valve operation to ensure that it is opening completely and not limiting water flow and that it is shutting off completely. - Check system and zone pressure improper pressures can cause distribution uniformity problems. Refer to the sprinkler head manufacturer for specifications. If all system components are functioning properly move the bisensor to a more appropriate area and then refer to Step 5: Re-running a 24-hour moisture threshold calibration. Step 5: Re-running a 24-hour Moisture Threshold Calibration 1) Re-saturate the soil. This may take several applications of water to ensure the water has penetrated to the level of the bisensor. 2) Compact the soil around and over the bisensor to ensure there are no air pockets around the bisensor. The bisensor is very durable but some care should be taken to not destroy the bisensor. Rock or gravel touching the bisensor directly can also cause a false reading. It may be necessary to remove any rocks that are in direct contact with the bisensor. 3) Once you are sure there are no air pockets around the bisensor, take a soil moisture reading by pushing the Read / Set button. This value will vary depending on soil type but should read above 20. A lower reading may mean there are remaining air pockets or rocks touching the bisensor. 4) Re-check area to ensure the bisensor location is still well saturated. 5) Run the 24-hour moisture threshold calibration: Hold the (+)(-) and (Bypass) buttons simultaneously for 3 seconds. The screen will flash between CAL 24H and the current moisture reading. The 24H will count down on the hour until the calibration is complete. Watering is paused during this time. Step 6: Soak Cycles Soak cycles allow the water to soak into the soil more efficiently, promoting healthier roots and a better looking site. It also reduces the potential for puddling and run-off, and allows the water to soak down to the bisensor, giving more accurate and timely readings. Soak cycles should be extended for sloped areas and denser soil types. When watering a site, it is important to allow enough time for water to soak into the ground. Run times should generally be long enough that 0.1 to 0.2 inches of water is applied before a soak cycle begins. Usually soak times are about 3 times as long as run times. This means that if you run your sprinkler system for 30 minutes, you allow 90 minutes for the water to completely soak into the ground. Refer to the manual for your sprinkler timer for the best way to set up soak cycles. 16 WaterTec S100 Manual June08

Step 7: Changing the Moisture Threshold The S100 Moisture Threshold calibration calculates a threshold for an average system. If the distribution uniformity at your site is above or below average it may be necessary to adjust the threshold for fine tuning. It may also be necessary once the roots have grown around the bisensor. While the Read / Set button is being held, use (+)/(-) buttons to change the moisture threshold. Raising the threshold will result in more frequent watering. Lowering the threshold will result in less frequent watering. note Note: Moving the threshold more than 0.2 in every 3 water cycles can cause erratic behavior. If your lawn is very dry, run a few extra cycles in order to catch up. Er1: Communication Error Incorrect Wiring. Bad Connections. Damaged Wire. Er2: Over Current Bad Valve Solenoid. Short Circuit Wires. Er3: Damaged bisensor Shown if the bisensor stick is damaged. Troubleshooting Error Codes Er4: 24-hour Moisture Threshold Calibration Failed This error is accompanied by one of the other five error codes to indicate reason for failure. Er5: Value Out of Range Warning This warning can occur only during 24-hour moisture threshold calibration, and indicates that the bisensor readings fall outside of the expected range. This could be caused by failure to saturate the soil with water in the beginning, or by accidental watering of the site after calibration started. If an Er4 occurs the S100 will determine the best possible moisture threshold based on the measured moisture values and allow the sprinkler system to water based upon this setting. Er6: Low Reading During 24-hour Moisture Threshold Calibration Error This error can occur only during 24-hour moisture threshold calibration and indicates that there was a low reading during calibration. To resolve this, follow the instructions under Step 5 on page 16. WaterTec S100 Manual June08 17
