INTRODUCTIONIn most installations, the Wireless Rain-Clik™ acts as a switch to break thecircuit to the solenoid valves of the irrigation system when it has rained. Thisallows the timer to advance as scheduled, but keeps the valves from openingthe water flow. Once the Wireless Rain-Clik™ has dried sufficiently, the switchcloses again to allow for normal operation. MOUNTINGStandard Mount:Using the screws provided, mount the Wireless Rain-Clik™ transmitter on anysurface where it will be exposed to unobstructed rainfall, but not in the path ofsprinkler spray. The switch-housing portion must be upright (as pictured), butthe swivel-bracket can be moved for mounting on any angled surface.Gutter Mount:Clip the enclosed gutter mounting bracket over the inside lip of the gutter. Attachthe Wireless Rain-Clik™ to the gutter mounting bracket with the screws provided.Helpful Hints for Mounting:A. When looking for a suitable location such as on the side of a building or post,the closer the Wireless Rain-Clik™ is to the controller, the better receptionwill be. DO NOT EXCEED 300 feet.B. The ideal location for mounting is not always the most practical location. Inthe case where a compromise must exist (such as low location on a side wallrather than the preferred high location), note that the Wireless Rain-Clik™will still work as it will always receive some rainfall – it just will not be asaccurate in its gauging as it could be.C. As described in the“Operation” section ofthis manual, “resetrate” refers to theamount of time it takesthe Wireless Rain-Clik™ to dry outsufficiently for thesprinkler system to beallowed to come backon. The mountinglocation will affect thisrate and should betaken into consider-ation should extremeconditions exist. Forexample, mounting theWireless Rain-Clik™on a very sunny,southern end of abuilding may cause theWireless Rain-Clik™to dry out sooner thandesired. Similarly,mounting on thenorthern end of abuilding with constantshade may keep theWireless Rain-Clik™from drying soon enough.Transmitters/Sensor•Nothing to set up withthis unit after installation•The unit can be testedstand-alone as follows:press and hold the poston the quick responsesection. Within 3seconds of pressingand holding this postdown, the LEDprotruding from thepotting should blinkonce. Release the post,within 3 seconds theLED should blink onceagain. (Figure 1) WIRING TO YOUR IRRIGATION SYSTEMImportant: The Wireless Rain-Clik™ is sold and designed for hook up to 24 Volt irrigation controllers only.WARNING! This unit isdesigned to be installed inconjunction with 24VACcircuits only. Do not usewith 110 or 220VACcircuits.Receiver Installation, SRC Controller:1. Using the hardwareincluded, mount thereceiver to the wall (useincluded wall anchors ifneeded). Make sure to putthe rubber cover/gasketunder the unit whenattaching it in an outdoorlocation.2. Attach the two yellow wiresto the AC terminals of theSRC (polarity does notmatter).3. Attach the blue wire to the RS terminal.4. Attach the white wire to the “C” terminal.5. Attach the valve common wire to the RS terminal.Receiver Installation, Pro-C and ICC Controllers:1. Using the hardwareincluded, mount thereceiver to the wall (useincluded wall anchors ifneeded). Make sure to putthe rubber cover/gasketunder the unit whenattaching it in an outdoor location.2. Attach the two yellow wiresto the AC terminals of thecontroller (polarity does notmatter).3. Attach the blue wire to oneSEN terminal and the whitewire to the other SENterminal of the controller.A. Receiver Installation, Other Controllers:1. Using the hardware included, mount the receiver to the wall (use includedwall anchors if needed). Make sure to put the rubber cover/gasket under theunit when attaching it in an outdoor location.2. Attach the two yellow wires to the AC terminals of the controllers (polaritydoes not matter).3a. Most controllers use anormally closed rainsensor. To attach thereceiver to this type ofcontroller, attach the bluewire and the white wireto the sensor terminals ofthe controller, or in-linewith the valve common.3b. A few controllers on themarket require a normallyopen rain sensor. Toattach the receiver to thistype of controller, attachthe blue wire and theorange wire to thecontroller’s sensor input.®Wireless Rain-ClikTM Rain SensorsInstallation InstructionsFigure 3ControllerFigure 4GutterMountStandardMountWirelessRain SensorHunter SRCFigure 2RRSC 1ACAC 2 3WirelessRain Sensor Hunter ICCSENSENCTESTP MVACACGREMRed light indicatessensor is bypassedGREEN = Sensor is dryRED = Sensor is wetSENSOR BYPASSSENSOR STATUSWIRELESSRAIN SENSORRAIN SENSOR BYPASSPress to bypass, pressagain to re-enableP MVCWirelessRain SensorAC ACWBYYVALVESBWYYWBYYCommon Wireto all ValvesFigure 1Manually depress the spindle atthe top of the Wireless Rain-ClikTMRed light indicatessensor is bypassedGREEN = Sensor is dryRED = Sensor is wetSENSOR BYPASSSENSOR STATUSWIRELESSRAIN SENSORRAIN SENSOR BYPASSPress to bypass, pressagain to re-enableRed light indicatessensor is bypassedGREEN = Sensor is dryRED = Sensor is wetSENSOR BYPASSSENSOR STATUSWIRELESSRAIN SENSORRAIN SENSOR BYPASSPress to bypass, pressagain to re-enable
B. 24 Volt Solenoid Valveswith Booster Pump(See Figure 5)Locate the common wireto the solenoid valves andthe common wire leadingto the coil of the relay thatstarts the pump. If thesetwo wires are connectedto the “common” terminalon the controller,disconnect both of them.Twist together these twowires along with one wirefrom the Rain-Clik™, andsecure with a wire nut.Attach the other wire ofthe Wireless Rain-Clik™receiver to the “common”terminal on the controller.Note: The pump circuitoutput must be 24 Voltsin this situation. Do not proceed if 110V.Learning the transmitter address at the receiver:•Units purchased as a kit will already have their address learned.•Each transmitter produced has a unique address hard-coded into it. A receivermust learn this address to work with that transmitter. This step will only benecessary if transmitters and receivers are purchased separately.1. Prior to applying power (yellow wires) to the receiver, press and hold thereceivers pushbutton.2. While the pushbutton is being held apply power to the receiver – the receiver’s“sensor status” LED should light up yellow indicating the receiver is ready tolearn an address.3. Push and hold the quick response post on the transmitter/sensor.4. Within 4 seconds, the receiver’s “sensor status” LED should turn red.5. Release the transmitter/sensor’s quick response post and within 4 secondsthe LED on the receiver should turn green. The address is now learned andwill be retained even in the event of a power outage. OPERATIONOnce the receiver and transmitter have been installed and the receiver haslearned the transmitter's address, the system is ready to work. The receiver hastwo LEDs, which indicate the state of the system. The STATUS LED will be REDwhen the sensor is wet (watering disabled), and GREEN when the sensor is dry(watering enabled). There is also a RED BYPASS LED on the receiver. If thisLED is lit, the rain sensor is bypassed and watering will always be allowed. Eventhough the sensor is bypassed, the STATUS LED will continue to alert you of thestate of the sensor (Wet or Dry). If the communication between the transmitterand the receiver ever breaks down, the transmitter’s status LED will flash red. ADJUSTMENTS AND OPERATIONThe Wireless Rain-Clik™ can keep the irrigationsystem from starting or continuing after rainfall.The time that it takes the Wireless Rain-Clik™ toreset for normal sprinkler operation after the rain hasstopped is determined by weather conditions (wind,sunlight, humidity, etc.) These conditions willdetermine how fast the hydroscopic discs dry out,and since the turf is also experiencing the sameconditions, their respective drying rates will roughlyparallel each other. So when the turf needs morewater, the Rain-Clik™ is already reset to allow thesprinkler system to go at the next scheduled cycle.There is an adjustment capability on the WirelessRain-Clik™ that will slow down the reset rate. By opening the “vent” (see Figure6) to completely or partially cover the ventilation slots, the hydroscopic discs willdry more slowly. This adjustment can compensate for an “overly sunny”installation location, or peculiar soil conditions. Experience will best determinethe ideal vent setting. BYPASSING THE SENSORThe sensor may be bypassed by using the built in bypass feature in the SRC,Pro-C or ICC. On other controllers the sensor may be bypassed by pressing the“BYPASS” button on the receiver. The RED BYPASS LED on the receiver willbe lit when the sensor is bypassed. Pressing the “BYPASS” button again willcause the RED BYPASS LED to go back out thus re-enabling the sensor.Battery Life: The Wireless Rain-Clik™ transmitter is designed to work daily forup to ten years with the original battery. The sealed unit is available as areplacement part. Should you need to change the transmitter the receiver willhave to learn the new transmitter address.There is no required maintenance for the unit. The Wireless Rain-Clik™ doesnot have to be removed or covered for “winterizing” purposes. TROUBLESHOOTINGFollow these simple checks first before assuming the unit is bad and replacing it.System will not come on at all:A. First, check to see that the Wireless Rain-Clik™ discs are dry and the switch“clicks” on and off freely by pressing the top of the spindle.B. Next, look for breaks in the wire leading to the Wireless Rain-Clik™ receiverand check all wire junctions.System will not shut off even after heavy rainfall:A. Check wiring for correctness (see “Operation Check to Verify Correct Wiring”).B. Is the rainfall actually hitting the Wireless Rain-Clik™? Check for obstructionsto rainfall such as overhangs, trees or walls.Manufactured under U.S. Patent PendingAll Rain-ClikTM models are listed by Underwriters Laboratories, Inc. (UL).
