Usage identification is not 100% accurate due to variability in water supply installations. - Easy setup, no tools required to install. DESCRIPTION SENSOR: The Pleco sensor attaches to a functioning water meter and sends water usage information in near real time to the Pleco display. No tools are required to attach the sensor to the water meter. The sensor uses four (4) standard D-cell batteries that on average are expected to last over four months before being replaced. DISPLAY: The Pleco 5-inch touch-screen display receives sensor data and shows water usage in near real time. It works as a hub connecting to the Internet and the smartphone app. It can be wall mounted or placed on a counter or desk. The display should be within 50 ft. distance from the sensor for effective communication. It comes with a rechargeable battery that lasts over 1-hour. It is recommend to keep the display connected to the external power supply for continuous use. CONTAINER: The container used to ship Pleco is also used to calibrate the system. During calibration you will fill the container to the 1-Gallon water mark in order to start the system. All foam packaging materials should be removed from the container prior to calibration. APP: The Pleco app will show water usage in near real-time in your smartphone. It displays information similar to that on the Pleco display and provides a convenient way to monitor your water usage when you are away. 3 SETUP INSTRUCTIONS 1. Unpack and Power Up - Package contains: Sensor, Display, Container, USB charger, and USB cable. - Connect the power supply to an outlet and to the display and turn on the display. - Follow setup instructions on the display. 2. Attach sensor to water meter - Locate your water meter and make sure it’s sides are accessible. - Attach the sensor around the water meter (as a belt). Do NOT block the water meter reading dial. - Rest the battery enclosure on the ground. 3. Deploy sensor antenna - Unfold sensor antenna. - Use the telescoping mast to move the antenna up as close as possible to ground level. - Rotate antenna so that it is oriented parallel to the front of the house. 4. Setup and calibration - Use the display to setup the system, adjust date/time, connect to Wi-Fi, and to register. - Follow instructions on the display to initialize and calibrate the sensor. Remove all foam from container prior to calibration. - To power up the sensor tighten the battery enclosure lid. LED will light up. After initialization LED stays off. - Pleco is ready to use. 5. Install the smartphone app - The Pleco app is available at no extra cost at the Apple Store and Google Play. 4 DISPLAY SCREENS The Pleco display and smartphone app user interface consists of several screens used to provide water usage information and change system settings. The user navigates through the various screens by selecting the icons and menus on the touch-screen display and smartphone app. Home Screen The Home screen shows the total water usage in the current day and time. It also displays a daily water usage limit that is set to a default value and can be changed by the user through the settings screen. Information on sensor signal strength, time, wi-fi connection, and battery charge are shown on the top of the screen. Icons on the right of the screen are used to navigate to other screens as indicated in the figure below. What Screen The What screen shows what the water was used for. The system identifies 5 different types of water usage: Faucet, flush, shower, irrigation, and other. Due to variations in the water supply systems, the identification is not perfect and some water usage may be misidentified. Icons on the right of the screen are used to select usage for the current day, week, or month as shown in the figure below. Touching the pie chart will show the water used for the type selected. Sensor signal strength wi-fi connection Display battery charge Sensor low-battery warning What screen When screen Settings screen Daily water usage and Time history screen Daily water usage limit Time Water usage left to reach daily limit Current day Current week Current month Time history screen Home screen 5 When Screen The When screen shows when the water was used. Icons on the right of the screen are used to select usage within the current day, week, or year as shown in the figure below. The scale icon on the top-right of the screen toggles between showing and hiding the usage for the previous time period for comparison. Time His…

Test setup photos 4.User's manual 2. External photos3. Internal photos These documents contain detailed system and equipment descriptions and related information about the product, which manufacturer/applicant considers to be proprietary. confidential, and a custom design and otherwise, would not release to the general public. Since this design is a basis from which future technological products will evolve, manufacturer/applicant feels that this information would be of benefit to its competitors, and that the disclosure of the information in these documents would give our competitors an unfair advantage in the market. Grantee will not market or distribute product during the Short-Term Confidentiality period requested. When the device is ready to be marketed the grantee will inform the TCB to release the Short-Term Confidentiality. Please contact me if there is any information you may need.
