Troubleshooting

Watering Issues

Problem	Possible Cause	Possible Solution
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.

Safety Information

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.

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.

If the supply cord of an outdoor controller is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
If the supply cord of an indoor controller is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent.

If the electrical cord for models ESP-TM2 AUS is damaged, it needs to be replaced with the following:
Flexible supply cord H05VV-F
Minimum wire size of 0.75mm^2 (18 AWG). For Direct Connect wiring, the minimum wire size is 0.75mm^2 (18 AWG).

Outdoor controller shall be permanently connected to fixed wiring by a flexible cord, and have a cord anchorage. The cord anchorage shall relieve conductors from strain, including twisting, at the terminals and protect the insulation of the conductors from abrasion.

NOTICE
Use only Rain Bird approved accessory devices. Changes or modifications not expressly approved by Rain Bird could void the user's authority to operate the equipment. Unapproved devices may damage the controller and void the warranty. For a list of compatible devices go to: www.rainbird.com
