Installation and Setup
Mount the RainBird ESP‑TM2 on a wall, connect power to a grounded outlet, and rotate the dial to MANUAL STATION to test valves. Set to AUTO RUN for schedules, use RUN DAYS to pick odd/even days, and toggle the rain sensor to ACTIVE or IGNORE.and verify all connections.
Power and Wiring Connections
The RainBird controller requires a 120 V AC source with a grounded outlet. Before connecting, verify that the circuit breaker is on and the outlet is properly grounded. Use a 3‑wire cable: line (black), neutral (white), and ground (green or bare). The controller’s power terminals are labeled L, N, and G. Connect the line to the black wire, neutral to white, and ground to the green wire. Ensure all connections are tight and insulated.
After wiring, set the controller to MANUAL STATION by turning the dial to the station icon. This allows you to confirm that each valve opens and closes correctly. If a valve does not respond, double‑check the wiring at that station and the valve’s own power connections.
For controllers with a rain sensor, the sensor’s power is supplied through the same 120 V line. The sensor’s terminals are labeled RS+ (positive) and RS‑ (negative). Connect RS+ to the line and RS‑ to the neutral. The sensor will automatically cut power to the controller during rainfall when set to ACTIVE.
When installing in a wet location, use a weather‑proof enclosure rated at least IP65. Seal all cable entries with silicone or a weather‑proof sealant to prevent moisture ingress. Verify that the enclosure’s ventilation is adequate to avoid overheating.
Finally, perform a test run: set a short program, observe the timer, and confirm that the controller displays the correct remaining run time. If the display shows an error or the system does not operate, check for loose connections, a tripped breaker, or a damaged cable.
All wiring should be inspected for corrosion and secure connections. Use conduit for exposed runs, and label each terminal. Keep controller manual reference!!.
Valve and Emission Installation
Mount the RainBird controller on a sturdy wall so the dial is easily reachable. Each irrigation station is linked to a solenoid valve that opens when the controller signals. Wire the valve’s power leads to the corresponding station terminals on the controller, using the color‑coded system: black for line, white for neutral, and green for ground. After wiring, rotate the dial to the MANUAL STATION position to test each valve individually. This confirms that the solenoid opens and closes correctly and that the water pressure is adequate for the zone.
When the valves respond correctly, set the dial to AUTO RUN to begin a scheduled program. The controller will display the station number or program name and the remaining run time on the LCD. This real‑time feedback lets you verify that the emission timing matches the programmed schedule. If the display shows an unexpected station or a run time that is too short or long, double‑check the wiring and the valve’s mechanical condition.
For multi‑zone systems, you can use the RUN DAYS setting to limit watering to odd or even calendar days. Rotate the dial to RUN DAYS and select the desired option. This feature is especially useful for conserving water during periods of high rainfall. If you need to override the rain sensor, you can set it to IGNORE or ACTIVE by rotating the dial to the rain sensor icon and choosing the appropriate mode. The controller will then either continue watering during rain or pause until the rain stops, depending on the setting.
After setting the run days, perform a pressure test on each valve. Attach a pressure gauge to the outlet of a valve, run a short program, and record the pressure drop. A drop of less than 5 psi indicates a properly functioning valve; a larger drop may signal a blockage or mechanical failure. Inspect all valves for leaks or loose fittings, tightening pipe clamps and ensuring all connections are secure. Replace any valve that shows signs of corrosion or wear.
Finally, run a full system check by executing a short test program on all stations. Observe the emission from each valve, verify that the controller’s LCD updates correctly, and ensure that the water pressure remains stable across all zones. If any valve does not emit water, inspect the valve’s internal components for blockages or mechanical failure. Proper valve maintenance and regular emission checks will extend the life of your irrigation system and maintain efficient water use.
Programming Basics
Set up basic schedules by rotating the dial to AUTO RUN, selecting a station, and entering desired start time and duration. Use the LCD to confirm settings. Toggle between manual and auto modes to test immediate watering or scheduled operation. Adjust settings as needed for optimal!
Setting Up Basic Schedules
Begin by rotating the controller dial to the AUTO RUN position. This places the unit in schedule mode, allowing you to create or edit programs. Use the LCD display to navigate to the desired station number by pressing the + or ⸺ buttons until the station indicator matches the valve you wish to program. Once the station is selected, press the SET button to enter the start time. The display will prompt you to set the hour, minute, and AM/PM designation. After confirming the start time, the controller will ask for the run duration. Input the number of minutes the valve should remain open; the ESP‑TM2 supports a minimum of 1 minute and a maximum of 120 minutes per run. Confirm the duration by pressing SET again. The system will now display the remaining run time and the station number, indicating that the program is ready; To activate the program, simply turn the dial to AUTO RUN and the controller will automatically trigger the valve at the scheduled time. If you need to adjust the schedule later, repeat the process: select the station, press SET, modify the time or duration, and confirm. For multi‑station setups, repeat these steps for each station, ensuring that overlapping times are avoided to prevent excessive water pressure. Additionally, the RainBird controller allows you to assign each program to either odd or even calendar days. Access this feature by rotating the dial to RUN DAYS, selecting the desired program, and toggling between ODD or EVEN. This flexibility lets you tailor watering frequency to seasonal needs. Finally, remember to check the rain sensor setting: rotate the dial to RAIN SENSOR and choose ACTIVE to have the controller pause irrigation during rainfall, or IGNORE if you prefer to maintain the schedule regardless of weather. By following these steps, you establish a reliable, automated watering routine that conserves water and keeps your landscape healthy. Ensure that the controller’s internal clock is set correctly to match your local time zone, as this affects all scheduled events.
Manual vs. Auto Mode Operation
The RainBird ESP‑TM2 has two modes. In Manual mode, rotate the dial to MANUAL STATION. The selected valve opens for the duration stored in its last program, and the LCD shows the station number and remaining run time. Stop early by turning the dial back to AUTO RUN or pressing STOP. Manual mode is useful for spot‑watering, troubleshooting, or overriding the schedule. In Auto mode, set the dial to AUTO RUN. The controller follows the programmed schedules for each station, starting at the programmed times and running for the programmed durations. Auto mode respects the rain sensor: if the sensor is set to ACTIVE and rainfall is detected, the controller skips that day’s run. Switching between modes is instant; the controller keeps the last program settings, so returning to Auto resumes the normal schedule. Users can lock the dial to prevent accidental changes. The ESP‑TM2 also lets you set RUN DAYS (odd or even) and combine it with Manual or Auto modes to limit watering to specific days. This flexibility allows tailoring watering to seasonal patterns, water‑conservation goals, and user preferences. Understanding the difference between Manual and Auto operation is essential for efficient water use and troubleshooting. In Auto mode, allows overrides: rotate dial to a station number and valve will run duration. LCD shows station and remaining run time, so you can stop early if necessary. This feature is useful for emergency watering or quick and fast today testing.
Rain Sensor and Run Day Settings
Set rain sensor to ACTIVE or IGNORE via RUN DAYS dial. Use days to limit watering! Adjusting threshold can be set in the controller’s menu.The sensor’s threshold can be set to skip watering showers, saving water daily. Setting the rain sensor to ACTIVE skips watering on wet days, saving water reducing runoff.
Configuring Rain Sensor Behavior
To set the RainBird ESP‑TM2 rain sensor, first locate the sensor switch on the controller. Turn the dial to RUN DAYS and select RAIN SENSOR. The display will show ACTIVE or IGNORE. Select ACTIVE to have the controller skip watering when moisture is detected, or IGNORE to run regardless of rain. The sensor’s threshold is adjustable by pressing the SET button while the sensor mode is highlighted. Use the + or ⸺ buttons to increase or decrease the moisture level required to trigger a skip. Once set, press ENTER to confirm. The controller will now automatically adjust watering schedules based on real‑time moisture readings, conserving water and preventing over‑watering during wet periods. Remember to test the sensor by simulating rain or using a spray bottle to ensure the skip function activates correctly. When the sensor is set to ACTIVE, the controller reads moisture levels every 10 minutes during scheduled runs. If the moisture exceeds the threshold, the run is paused and resumed once conditions improve. Adjusting the threshold allows fine‑tuning for different soil types; sandy soils may need a lower threshold than clay. The controller logs each skip event in the memory, which can be reviewed via the LCD or connected to a smart phone app. This feature helps users verify that the sensor is functioning correctly and that water savings are achieved. For advanced users, the RainBird system offers a manual override that can be accessed by pressing the RUN button while the controller is in AUTO mode. This allows temporary watering of a single station regardless of the rain sensor or schedule. Additionally, the system supports remote programming via a USB interface, enabling technicians to upload custom schedules or firmware updates without needing to be physically present at the controller. This flexibility is ideal for large commercial installations where multiple controllers must be managed efficiently.
Setting Odd and Even Calendar Days
To configure the RainBird ESP‑TM2 to water only on odd or even days, first turn the controller dial to RUN DAYS. The LCD will display the current selection, such as EVEN or ODD. If the desired setting is not displayed, press the + or ⏤ buttons until the correct option appears. Once selected, press ENTER to confirm. The controller will now apply this rule to all scheduled programs, ensuring that watering occurs exclusively on the chosen calendar days. If you need to switch back, repeat the process and select the opposite option. This feature is particularly useful for conserving water during periods of high rainfall or for meeting local irrigation regulations that limit watering days. The setting is stored in the controller’s memory, so it persists even after power cycles. For advanced users, the RainBird system allows the combination of odd/even day settings with rain sensor overrides, providing a flexible approach to irrigation scheduling. Always verify the new setting by checking the LCD after a power cycle; the display should still show the selected day type. If the controller does not retain the setting, ensure that the battery backup is functioning and that the firmware is up to date. The RainBird ESP‑TM2 also supports manual overrides via the RUN button, allowing a single station to be watered regardless of the odd/even rule. By mastering the odd/even calendar day configuration, users can achieve precise control over irrigation timing, reduce water waste, and maintain healthy landscapes with minimal effort
