Warranty I ˊ FCC Statement OWNERS MANUAL MODEL WS-2000 - 3 - The SmartMeter Fill System The SmartMeter was invented to help solve problems associated with manually filled pools. This system has three major components. These components are thePod Sensor, the Valve Controller and the remote Water Valve. A Toro Professionals Series valve is included with the system to help insure success. The Toro valve specifications allow more than 180 feet of 18GA wire. Combined with typical radio transmission ranges in excess of 20 feet you should have over 200 feet of distance between the “Pod Sensor” in the pool and the “Water Valve”. Three major components - Pod Sensor, Valve Controller and remote Water Valve Overview of the SmartMeter Fill System The System works by sending water level signals to the remote controller. The “Pod Sensor” sends wireless signals by radio to the nearby “Valve Controller”. The Valve Controller receives the level signal and operates the “Water Valve”. Upon installation, the Valve Controller is programmed for a preferred “set level”. The “set level” for the “Pod Sensor” should be at the same level as the preferred level of operation for your pool and spa. This level should also coincide with the suggested level of the water line at the Pod Sensor finger. All of this is explained in this manual. OWNERS MANUAL MODEL WS-2000 - 4 - The SmartMeter Fill System has two modes of operation. MODE 1 provides a continuous auto-fill function and MODE 2 is considered a water saver mode. Mode 1 measures water level and updates Water Valve every 10 minutes, 24 hours a day. Mode 2 measures water less frequently. Mode 2 “sleeps for 23 hours each day and only takes measurements during one hour of “wake” time. During the fill cycle “wake” hour, water level measurements and Water Valve updates occur 6 times, once every 10 minutes. During installation the fill cycle “wake” hour is predetermined and programmed by you. The SmartMeter Fill System was intended as an upgrade for pools that currently do not have an auto-fill system or an auto-leveler. The SmartMeter can also upgrade pools with float-type mechanical auto-fill systems. Pod Sensor The Pod Sensor measures the water level. It fits under a deck lid. Refer to Installation Instructions for more specific details on installation options. Valve Controller The Valve Controller receives the wireless signal from the Pod Sensor and operates the Water Valve accordingly. The Valve Controller is your only programming interface. On this controller are a RESET button along with a GREEN LED and a RED LED. The Valve Controller contains 6 “AA” batteries. OWNERS MANUAL MODEL WS-2000 - 5 - This figure shows a drawing of the programming interface of the Valve Controller Water Valve A Toro Professional 1” Valve is included with the SmartMeter Fill System. This valve has a variable flow function. The Water Valve allows you to have some control over the volume and flow of water sent into the pool, spa or water feature. The Toro Professional Water Valve included can deliver a wide range of flow requirements. This valve can reliably deliver as little as 0.1 gallons per minute.

Data is based on specifications from Toro on the 1” female NPT and for the TPVF100DC at typical line pressures. Your installation will be different. For installation consult a plumbing professional. Pre-Installation Decisions OWNERS MANUAL MODEL WS-2000 - 6 - CHOOSE Mode 1 or Mode 2 Mode 1 is considered a continuous auto-fill method. Mode 2 is considered the “water saver” method. This is an important feature of the SmartMeter WS-2000. Mode 2 allows for a water loss indication and automatic water shut off. There is no water loss detection or automatic shut off capabilities for Mode 1. MODE 1 - rapid auto-fill mode (No Water Saver Function) xEvery 10 minutes measures water level and updates valve xWater Valve turns off only if Pod Sensor signal is lost or batteries low MODE 2 - regular fill mode. (“Water Saver”) x 23 hours a day does NOT take measurements x 1 hour per day measures water level and updates valve 6 times (Once every 10 minutes during hour of wake time) x Water Valve automatically shuts off if “set” level is not achieved for three consecutive days If SmartMeter detects that set level was not achieved for three consecutive days it shuts off the Water Valve and the RED “error” LED light flashes. This indicates a possible water loss or leak. This automatic shut-off function is intended to save water and to inform you of a possible water loss. Visual…

Applicant：Dongguan Southstar Electronics Limited FCC ID：X8CWS-2000 Operation Description The transmitter is a universal SDR RF transmitter chip AX5051. The U1(AX5051) has an integrated RF frond end with modulator and demodulator, communication controller and communicates the microcontroller via a SIP buss. U4(MCP1700T-3302E/TT) is a power management chip and provides host with 3.3V power. U6(MC14521BDR2G) is the source of the clock of 1 second. U3(ATMEGA88PA-AU) is a High Performance, Low Power AVR 8-Bit Microcontroller used to interface with the radio frequency chip U1 on the SIP buss, read data from U2(PIC18F24J11-I/SS), and report data. Finally, all information is measured and reported to the receiver unit. Antenna is formed by two copper wire configured in a dipole. Common grounding on PCB is not connected to real external ground. Power supply is DC 6V by four “AA” batteries.
