Introduction

Welcome to Rain Bird
Thank you for choosing Rain Bird’s ESP-TM2 controller. In this manual are step-by-step instructions for how to install and operate the ESP-TM2.

Controller Features

Installation

Mount Controller

1. Drive a mounting screw into the wall, leaving a 1/8-inch gap between the screw head and the wall surface (use the supplied wall anchors if necessary), as shown.
2. Locate the keyhole slot on back of the controller unit and hang it securely on the mounting screw.
3. Remove the wiring bay cover on the lower part of the controller unit, and drive a second screw through the open hole inside the controller and into the wall, as shown.
   • NOTE: Choose a suitable mounting location close to a 120 VAC wall outlet.

Wiring Connections

Connect Valves

1. Route all field wires through the opening at the bottom of the unit, or through the knock-out in back of the unit. Attach conduit if desired, as shown.
2. Connect one wire from each valve to one of the numbered station terminals (1-12) on the controller, as shown.
3. Connect a field common wire (C) to the common terminal (C) on the controller. Then connect the remaining wire from each valve to the field common wire, as shown.
   • NOTE: The ESP-TM2 controller supports one valve solenoid per station terminal.
   • Connect Master Valve (optional)
4. Connect a wire from the master valve (M) to the master valve terminal (M) on the controller. Then connect the remaining wire from the master valve to the field common wire, as shown.

Connect Pump Start Relay (optional)
The ESP-TM2 can control a pump start relay, to turn the pump on and off as needed.

1. Connect a wire from the pump start relay (PSR) to the master valve terminal (M) on the controller. Then connect another wire from the pump start relay to the field common wire, as shown.
2. To avoid the possibility of damage to the pump, connect a short jumper wire from any unused terminal(s) to the nearest terminal in use, as shown.
   • NOTE: The ESP-TM2 controller DOES NOT provide power for a pump. The relay must be wired according to manufacturer instructions.

Only the following Rain Bird pump start relay models are compatible with the ESP-TM2:

Connect Rain/Freeze Sensor (optional)

The ESP-TM2 controller can be set to obey or ignore a rain sensor. Refer to the Rain Sensor section under Advanced Programming.

1. Remove the yellow jumper wire from the SENS terminals on the controller.
2. Connect both rain sensor wires to the SENS terminals, as shown.
   • NOTE: Do not remove the yellow jumper wire unless connecting a rain sensor.
   • NOTE: Rain Bird controllers are only compatible with normally closed rain sensors.
   • NOTE: For wireless rain/freeze sensors, refer to installation instructions for sensor.
   • WARNING: Do not apply power until you have completed and checked all wiring connections.

Connect Custom Wiring (optional)
If desired, the provided 120-volt power cord can be removed and replaced with custom wiring. To remove the factory-installed power cord and connect custom wiring:

1. Ensure that the AC power is disconnected.
2. Remove the controller junction box cover and disconnect the power cord to the unit.
3. Remove the factory installed power cord by loosening the 2 screws securing the metal strain-relief bar, as shown.

4. Connect the external power supply wires using the wire nuts and then re-secure the metal strain relief bar by tightening the 2 screws.
   Power Wiring Connections (120VAC)

   Black supply wire (hot) to the black transformer wire
   White supply wire (neutral) to the white transformer wire
   Green supply wire (ground) to the green or green-yellow transformer wire

5. Verify that all wiring connections are secure and then replace the junction box cover.
   • CAUTION: The strain-relief bar must be re-secured for the unit to function properly.
   • WARNING: DO NOT apply power until you have completed and checked all wiring connections.

Troubleshooting

Watering Issues

The watering icon on the display is flashing, but the system is not watering| Water supply issue.| Verify there is no disruption to the main water line and that all other water supply lines are open and functioning.
Wiring is loose, not properly connected or damaged.| Check that wiring is securely connected at the controller and in the field. Check for damage and replace if necessary. Check wiring connections and replace with watertight splice connectors if needed.
Automatic and/or Manual Watering will not start| Connected rain sensor may be activated.| Let the rain sensor dry out or else disconnect it from the controller terminal block and replace it with a jumper wire connecting the two SENS terminals.
Jumper wire connecting the two SENS terminals may be missing or damaged.| Jumper the two SENS terminals on the controller terminal block by connecting them with a short length of 14 to 18 gauge wire.
Solenoid or master valve is shorted.| Confirm short message on the display. Correct the issue in the wiring. Clear the message by testing watering at the shorted valve or by pressing the button.
Excessive watering| Programs may have multiple start times that were set unintentionally| Programs (A, B or C) only require a single start time in order to run. Separate start times are not required for each valve.

Electrical Issues

main AC power supply is securely plugged in or connected and working properly.
Verify the orange power supply wires are connected to the controller “24 VAC” terminals.
The display   is frozen and the controller will not accept programming.| An electrical surge may have interfered with the controller’s electronics.| Unplug the controller for 2 minutes, then plug it back in. If there is no permanent damage, the controller should accept programming and resume normal operation.
Press and release the RESET button.

Safety Information

• WARNING: This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capacity, or lack of experience and knowledge unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

• WARNING: Special precautions must be taken when valve wires (also known as station or solenoid wires) are located adjacent to, or share a conduit with other wires, such as those used for landscape lighting, other “low voltage” systems or other “high voltage” power.
  Separate and insulate all conductors carefully, taking care not to damage wire insulation during installation. An electrical “short” (contact) between the valve wires and another power source can damage the controller and create a fire hazard.

• WARNING: All electrical connections and wiring runs must comply with local building codes. Some local codes require that only a licensed or certified electrician can install power. Only professional personnel should install the controller. Check your local building codes for guidance.

• CAUTION: Use only Rain Bird approved accessory devices. Unapproved devices may damage the controller and void warranty.
