Installation Guide Before You Start: Equipment and Power Requirements: INDOORS You need to have the WeatherTRAK controller and manual. There must be a power outlet within 6-8 feet of where the WeatherTRAK will be installed. If the valve wires are 16 gauge or heavier, you will need some 18-22 gauge solid valve extension wire (we recommend 20 gauge) and some wire nuts. OUTDOORS You need to have the WeatherTRAK controller, an outdoor box (from HydroPoint Data Systems, Inc.) and manual. There should be a junction box with 110VAC available near the proposed WeatherTRAK installation. You’ll need to bring power to the receptacle inside the outdoor box. Make sure you have some conduit and adapters available. You will need some 18-22 gauge solid valve extension wire (we recommend 20 gauge) and some wire nuts. Installation: Before you start, turn off the circuit breaker that powers the existing controller!!! Labeling: Make sure you know which station belongs to which wire before disconnecting the irrigation valve wires from the existing controller. Label or mark the wires accordingly. Also, make sure you identify the common wires and label them. Removing the Existing Controller: Unplug the power supply. If there is an internal transformer on the controller’s box, or the existing box is wired in, find the circuit breaker and turn it off. Then proceed to undo the existing wiring. Mounting the WeatherTRAK: INDOORS Make sure the new WeatherTRAK controller is at eye level for the expected operator and mount to the wall. If the valve wires do not reach, or the wires are 16 gauge or heavier, you may need to install a condolet box to bring WeatherTRAK Users Guide v1.33 Page 4 extension wires into the WeatherTRAK . Use 18 to 22 solid gauge valve wires so that they can fit inside the controller and connect the wires with wire nuts. Insert the previously labeled valve wires into the WeatherTRAK ’s connector strip securing each wire tip with a small straight blade screwdriver. There should be one or two common wires “C”; if a Rain Switch is being installed, wire in at “RS.” DO NOT REMOVE THE JUMPER AT THE "RS" POSITIONS UNLESS YOU INSTALL A RAIN SWITCH, OTHERWISE THE CONTROLLER WILL NOT IRRIGATE PROPERLY!!! (If your location uses a Master Valve or Pump, see the Master Valve section below.) When you replace the WeatherTRAK cover, be sure the COPY button moves freely and is not caught by the cover. Plug the transformer in the power outlet and plug into the WeatherTRAK . Turn the circuit breaker back on, verify all the valve wires are correctly installed, and then continue to SETUP . OUTDOORS Make sure the new outdoor box is at eye level for the expected operator and that there is clearance for the antenna sleeve. Mount the outdoor box to the wall using the appropriate anchors and screws. Use 18 to 22 solid gauge valve wires so that they can fit inside the controller, connect the wires with wire nuts, and conceal all connections behind the plate that holds the WeatherTRAK inside the outdoor box. Insert the previously labeled valve wires into the WeatherTRAK ’s connector strip securing each wire tip with a small straight blade screwdriver. There should be one or two common wires “C”; if a Rain Switch is being installed, wire in at “RS.” DO NOT REMOVE THE JUMPER AT THE "RS" POSITIONS UNLESS YOU INSTALL A RAIN SWITCH, OTHERWISE THE CONTROLLER WILL NOT IRRIGATE PROPERLY!!! (If your location uses a Master Valve or Pump, see the Master Valve section below.) When you replace the WeatherTRAK cover, be sure the COPY button moves freely and is not caught by the cover. The outdoor box requires direct connection to AC power. Make sure you connect the “ground” wire too. Use conventional conduit or flex conduit from the …

GEL Report File HP01-2003Operational Description Rev. AFCC ID Q4LWT0003 Glen Ellen LaboratoriesApril 26, 2003 Operational Description WeatherTRAK Circuit Operation The WeatherTRAK Irrigation Controller consists of two basic subsystems: 1. A microController-based sprinkler timer of conventional design. 2. A radio receiver optimized to receive Paging signals in the 928-932MHz band. The basic operating frequency of the microController is 10.240 MHz; radiation of this signal and its harmonics are very low because all of the high frequency signals are on-chip with very short radiating conductors. The radio receiver is a conventional triple-conversion superheterodyne circuit. A quarter-wave monopole antenna is fed through a highly selective SAW filter to a preamplifier with a gain of about 15dB. The signal is then block downconverted to a 70MHz IF by a 1 GHz local oscillator and an active mixer (highside injection). The 1 GHz LO and the preamp/mixer chain is shielded by fully enclosing metal cans. The LO to RF leakage from the first mixer is suppressed by the input SAW filter. The 70 MHz signal is then bandpass filtered and further downconverted to 10.7MHz by a frequency agile local oscillator working between 78.7MHz and 82.6MHz, which performs the channel selection function. After filtering at 10.7MHz, the signal is downconverted again to a 455KHz IF by means of a 10.245MHz local oscillator and mixer. The 455 KHz is limited and processed through a data slicer and then digitally demodulated by a custom Motorola decoder chip. When an incoming message is detected, the microcontroller retrieves the message from the decoder chip and uses the data payload to influence the irrigation schedule in the sprinkler timer.
