Page 3: Introduction
Introduction Thank you for purchasing DIG’s LEIT-2ET two station, weather based, ambient light (solar) powered, wireless irrigation controller, which operates as part of the LEIT-2ET wireless irrigation system. This manual describes how to get the LEIT-2ET controller up and running. After reading the manual and becoming familiar with the basic functions of the controller, the user can refer to the manual for less common tasks in the future. About the LEIT-2ET System The LEIT-2ET weather based wireless irrigation control system comprises the LEIT-2ET weather based two-station ambient light (solar) powered irrigation controller with a rain sensor connection, the LEIT RC2ET handset, and the LEIT WWS or LEIT WWSE ambient light (solar) powered weather station. Introduction The LEIT-2ET, a two station ambient light (solar) powered wireless irrigation controller, is an advanced and cost effective weather based wireless device that is programmed using the LEIT RC2ET remote control handset. Site information entered into the LEIT RC2ET remote control handset is downloaded into the LEIT-2ET controller, and with hourly weather data received from the LEIT WWS or LEIT WWSE wireless solar powered weather station, the LEIT-2ET controller calculates the daily local microclimate evapotranspiration (ET). The final result is used for a daily adjustment or override of the current scheduled irrigation program. The LEIT-2ET includes a photovoltaic module (PVM panel), 2 pairs of 18” (45 cm) station wires (labeled #V1 and #V2) used to connect the controller with up to two S-305DC solenoids, plus a pair of yellow wires for sensor connection. The LEIT-2ET has an ultra-compact photovoltaic module that harnesses light energy to generate electricity that is stored and used to power the controller day and night in any kind of weather. The programming and operation of the LEIT-2ET controller is conducted using the LEIT RC2ET remote control handset, which has an operating range of up to 350 ft (100 m) line of sight, by way of 2-way radio communication. After installation, no further visits to the controller are required. -
Page 4: Technical Assistance
IMPORTANT: Communication between the LEIT RC2ET remote control handset, the LEIT-2ET controller, and the LEIT WWS or LEIT WWSE weather station is automatically limited to daylight hours when there is sufficient light energy. Longer, brighter days will enable the system to operate over extended parts of the day. -

In order to begin communication with a new LEIT-2ET controller using the handset, a series of initial setup steps must be made. First, the user connects to the LEIT- 2ET controller via CONTROL ID 00 DEFAULT SETUP. Next, the user must assign the controller a new Control ID (recommended ID # 2-99). At this stage, the user can also change the existing Client ID of the controller (controller default Client ID is AAA) as long as it is also changed on the handset after exiting the controller program. In addition a descriptive controller address or name can be assigned to the controller with up to 14 characters to uniquely identify the location of each LEIT-2ET controller on the system. Step 1: Make sure the LEIT-2ET controller is out in bright light to harness light energy used to power the controller. It will take about 30 minutes, or less, in direct sunlight. Step 2: Splice the two (2) yellow (or yellow and black) sensor wires together using waterproof connectors. This splice will indicate that the controller is ready to... - Page 19 CONNECTED appears momentarily, then, CONTROL ID: 00, NO DESCRIPTION appears.

To assign a controller ID, press or and enter a number (1-9) for the first digit. Press and repeat the steps with the second digit (we recommend changing the ID number to a number higher then 01). Next, assign description, name or address (recommended). The default is NO DESCRIPTION. Press and the first letter of NO DESCRIPTION is blinking. Press or and enter a letter for the first digit. Press and repeat the steps for each letter. After completion, press to download the new information with the new ID number and address. Use the new ID number to connect to this controller and use the address or name to identify the controller location. c. Setting a new client ID (A-Z): The default ID is AAA (this is a security feature). If the controller CLIENT ID is changed from AAA to other letters, the user must update the handset to the same client ID after exiting the controller program. Repeat the steps to select a new ID. When finished, press to connect and upload the new information. ARE YOU SURE? screen appears. Press again to download the information. UPDATE SUCCESSFUL message will appear momentarily confirming that the controller received the information and Setup is updated and complete. After the update is completed the SETUP MENU appears. Exit SETUP MENU and the controller is ready to program. The user can now easily connect back to this controller using the newly assigned CONTROL ID and CLIENT ID. Repeat the steps to program additional controllers. NOTE: When connecting to a LEIT-2 controller, the controller and handset CLIENT ID must be the same. ATTENTION: The two yellow (or yellow and black) sensor wires are left connected so the RAIN OFF alert will not appear. If a rain sensor needs to be added, see Section 4 – Using a Sensor.

It is best to troubleshoot this DC system (like an AC system) by a process of elimination with the goal being to determine which component(s) has failed. The following facts and tips may be helpful to eliminate certain components and facilitate faster troubleshooting. It is assumed that these are installed controllers that are receiving the proper amount of light. Keep in mind that the problem may be with more than one component. -
Page 22: Troubleshooting Controller
1. T o test the controller’s output, connect a solenoid to one of the controller’s red and white wire pairs. Institute a test run via the handset with one (1) minute on the station in question and zero (0) minutes on the other station. If the solenoid is not installed, verify that the plunger retracts and extends or that you hear the sound of the plunger latching. If the solenoid is installed onto a valve, see that the valve turns on and the sprinklers or drip system is working. If it does not turn on, the plunger does not retract and extend, or no sound is heard of the plunger latching, repeat the process using a second solenoid. If the problem continues you may have an issue with the controller wires and the WATERPROOF CONNECTORS. 2. T he LEIT-2ET controllers function only with S-305DC solenoids or 305DC-XXX valves. 3. T he LEIT-2ET controllers function only with compatible sensors (HUNTER MINI-CLICK or RAIN BIRD RSD). 5.2 Troubleshooting Solenoids 1. V erify that the correct solenoid and adapters are being used for the valve in question. 2. V erify that the white and red wires from the solenoid are connected to the white and red wire pair on the controller and that these splices are tight and corrosion free. 3.
