Rain/Freeze Transmitter will also prevent watering in freezing conditions. Important! Before connecting wires, you must determine whether your controller uses “Normally Open” or “Normally Closed” wiring for sensors. All Rain Bird controllers, and most other manufacturers’ controllers, are installed using a “Normally Closed” wiring method. Note: The Wireless Rain Sensor is a low-voltage device compatible with all 24 volt alternating current (VAC) control circuits and 24 VAC pump start relays. Normally Closed Installation Note: The lead wire labeled “NO” is not used with this installation method. The Wireless Rain and Freeze Sensor is a very sophisticated Sensor Transmitter and Receiver system designed to work with all 24 volt alternating current (VAC) control circuits and 24 VAC pump start relay circuits. The Receiver has three Light Emitting Diodes (LEDs). Each LED can indicate two conditions. If the LED is solid then the condition labeled on the left is occurring. If the LED is blinking the condition labeled on the right has taken place. These are explained on page 7. Controllers With Sensor Input 24V 24V GND SENSOR SENSOR 1. Installation Many modern controllers (such as Rain Bird’s E Class, ESP-LX+, and ESP-MC) include built-in terminals for sensor input. Dedicated terminals are usually labeled “sensor” or “SN” on the controller’s terminal strip. See Illustration 3. RED BLACK GREEN BROWN MV COM 1 1. Connect the Red and Black leads to the two 24VAC terminals on your controller. (It is not important which wire goes to which terminal.) ORANGE ORANGE Note: Follow the installation instructions carefully and install the unit only in full compliance with the National Electrical Code (NEC) or your local electrical code. TRANSFORMER There are two components of the Wireless Rain Sensor product, the Sensor Transmitter and the Receiver. TO RECEIVER Important!: Begin by installing the Receiver and test the two components (transmitter and receiver) side by side before mounting the Sensor Transmitter. 2. To connect the Rain and Freeze Sensor, remove the jumper wire (if present) from the controller’s sensor terminals. 3. Connect the Green lead and the Brown lead to the Sensor Terminals on your controller. Wireless Rain and Freeze Sensor Receiver Mounting 1. Select a place near your controller where you will install the Receiver. Ensure that there will be room for the receiver antenna and that the leads will reach to the sensor connection on your controller (approximately 24 inches). Controllers Without Sensor Input Use the procedure below if your controller does NOT have dedicated sensor terminals. See Illustration 4. Note: The Receiver unit is weather resistant and is suitable for mounting near an outdoor controller. 1. Connect the Red and Black leads to the 24 VAC terminals on your controller. 2. Secure the bracket to the wall near your controller with appropriate fasteners. Be sure to install the bracket with the flanges facing out away from the wall. See Illustration 1. 2. Disconnect the valve common wire from the common terminal (“C” or “COM”) on the controller’s terminal strip. Connect the valve common wire to the green lead on the Sensor Receiver. 3. Slide the water resistant receiver unit down onto the mounting bracket. See Illustration 2. 3. Connect the Brown lead to the “COM” terminal on the controller’s terminal strip. 4. Attach the red “Notice” sticker to your automated irrigation system control panel. 5. Attach the gray “Receiver” memory sticker to the side of the Receiver. Receiver Memory Record Mount Receiver bracket near existing controller. Slide Receiver down on to the mounting bracket. Install bracket with flanges facing out from the wall. WRS Wireless Rain and Freeze Sensor Normally Open Installation Some non-Rain Bird controllers require rain sensors to be installed “Normally Open” (“NO”). In this case, substitute the White Lead for the Brown Lead in the installation for a “Normally Closed” (“NC”) installation (above). Be sure to consult with the controller manufacturer’s manual to determine the appropriate procedure for connecting the Rain Sensor to your controller. Note: In this case, the brown wire will not be used. WRS-100 Wireless Rain Sensor Testing the Transmitter and Receiver Pair If you bought the Transmitter and Receiver together, they were programmed at the factory to work together. If you purchased them separately, or, if the following test procedure doesn’t work properly, it may be necessary to program the receiver to work with the transmitter. Use the following procedure to test the two units together. See Illustration 5. Test Sensor Transmitter with Receiver Watering Suspended SENSOR BYPASS WATERING SUSPENDED BY SENSOR 1. Push and hold the pin for a few seconds on the top of the Sensor Transmitter. 2. If the Receiver detects the signal, the Red LED will begin to indicate “Watering Suspended”. Sensor Transmitter Mounting and Low Power Test This procedure allows a single installer to mount and test the Sensor Transmitter and Receiver for communication. See Illustration 7. The Low Power Test helps to ensure that the Wireless Sensor will continue to operate even under conditions of radio interference or weakening batteries. Select an appropriate mounting location as described above. Drive two mounting screws through the mounting holes in the mounting bracket. Use fasteners appropriate for the mounting surface (wood, tile, masonry, etc.). Be sure to test the reception of the signal from the sensor, in this location, to the receiver using this procedure. 3. You can release the Transmit button and continue with the installation. Programming the Transmitter and Receiver Pair 1. Push and hold the Transmitter button for at least four (4) seconds (but not more than 14 seconds). If a Receiver unit does not successfully receive a Sensor Transmitter signal, use the following procedure to program the Receiver to recognize the Sensor Transmitter. It is possible to program a Receiver to receive signals from up to five Sensor Transmitters. This allows your Receiver to work with multiple sensors that may be used to interrupt watering. 2. The Sensor Transmitter will send a signal with lower than normal power. 1. Press and hold the bypass switch on the Receiver button until the Green LED begins to blink rapidly, then release (Green LED will then begin to blink approximately once per second). 2. Operation 2. Activate the transmitter (by pushing the pin on the top of the Sensor Transmitter) until a clicking noise is heard from the receiver and the Red LED indicates “Watering Suspended”. 3. If more than one click is heard, this means multiple transmitters are programmed into this Receiver unit. The number of clicks will indicate how many of five locations have been programmed. 4. To exit the Program Mode prior to activating the Transmitter, push and release the Receiver button. If the Transmitter is not activated for thirty (30) seconds after the Receiver is in Program Mode, the Receiver will return to Sensor Bypass Mode. Selecting a Location for the Sensor Transmitter Select a mounting location where the rain-sensing head will receive direct rainfall. Make sure the head extends beyond the roof line, tree limbs, and any other obstructions. Install the Sensor Transmitter in an area that receives as much rain and sunlight as the grass. 3. If the Receiver detects the signal, the Red LED will begin flashing for a duration of 2.5 minutes. This allows a single installer time to return to the Receiver to verify the signal was received. If the LED is flashing, the selected Transmitter location is within range. Set Rainfall Setting The rainfall setting determines the amount of rainfall needed to prevent your irrigation system from watering. You can adjust the rainfall setting from 1⁄8" to 3⁄4" (5mm to 20mm). The ideal rainfall setting for your location depends on soil type, humidity, amount of direct sunlight the sensor receives and frequency and amount of rainfall. The table below gives some guidelines to help determine the appropriate rainfall setting. (See table) Note: At the 1⁄8" or 5mm setting , a very light rainfall will activate the sensor and suspend watering. The 1⁄8" or 5mm rainfall setting is not recommended in areas with high humidity. To set the rainfall setting, turn the sensor dial cap until the desired rainfall setting lines up with the arrow on the sensor body (A), as shown in Illustration 8. WRS Wireless Rain and Freeze Sensor Rainfall setting • Dry climate/low humidity ⁄8" to 1⁄4" (5mm to 10mm). • Infrequent, light rains • Sensor receives long periods of direct sunlight • Clay-type soils Be sure to mount the sensor above spray from sprinklers. Avoid mounting locations such as those shown in Illustration 6. Be sure that the sensor is located within range of the receiver portion of the Wireless Rain Sensor system. See “Testing the System” section. Irrigation site conditions • Moist climate/high humidity ⁄2" to 3⁄4" (15mm to 20mm). • Frequent, heavy rains • Sensor mounted in a mostly shady area • Sandy soils WRS Wireless Rain and Freeze Sensor Set Vent Ring 5. Functional Mode Summary The vent ring determines “drying time” – the length of time the sensor turns off irrigation after a rainfall. For most installations, set the vent ring to the fully open position. Monitor For some installations, such as sites where water pools after rainfall, set the vent ring to a partially open position. This will shut down the irrigation system a little longer after a rain. Vent Ring To set the vent ring, turn the vent ring knob below the dial cap to the desired position, as shown in Illustration 9. 3. Testing the System It is recommended that you check the Transmitter and Receiver side by side prior to mounting the Sensor. It is also recommended that the Low Power Test be completed successfully. Once installed, the completed system can be tested by turning on any controller irrigation zone, verifying that zone does come on, and then pressing down on the Rain Sensor pin located on the top of the dial cap. The irrigation system should stop watering within a few seconds. If the system does not shut off, review the installation process to ensure the system is correctly installed. For assistance, call Rain Bird Technical Services at 800-247-3782 (USA and Canada only). 4. Maintenance The Wireless Rain Sensor operates automatically and usually requires no regular maintenance other than replacing the batteries in the Rain and Freeze Sensor (Transmitter) every three (3) years. Replace the batteries with two Panasonic CR2032 3V or equivalent replacement. Rain Bird Part Number 651009 - CR2032 lithium battery. In addition, the fibrous disks inside the Transmitter dial cap sometimes become contaminated with debris or insects. If this happens, use the following procedure to clean the Rain Sensor. 1. Turn the dial cap to the 3⁄4" rainfall setting, as shown in Illustration 10. 2. Press the tab labeled “Press” on the side of the sensor body. Then turn the dial cap about 1 and 1⁄4 turns further to remove the cap from the sensor body. 3. Remove the plunger and disks from the sensor body, and wash them in clean water. 4. Reinstall the plunger and disks into the cap first, then screw the cap onto the sensor body. Reset the rainfall setting to the desired position. The Monitor Mode is the normal mode of operation once the Transmitter and Receiver unit(s) have been installed. While the transmitter is in Monitor Mode, it will transmit a signal on a change of state (such as rain received) or at a fixed interval to confirm that a communication link still exists. While the Receiver is in Monitor Mode, it will continually listen for signals from the Transmitter(s). Program The Program Mode allows for a Transmitter to be programmed into a receiver to allow one-way communication. Each Receiver is capable of holding five (5) Transmitters in its memory. Press and hold the Bypass Switch on the Receiver until the Green LED begins to blink rapidly, then release (Green LED will then begin to blink approximately once per second). To program the Transmitter into the Receiver, activate the Transmitter by holding down the pin at the top of the Sensor Transmitter until a clicking noise is heard from the Receiver. The number of clicks will indicate which one of five locations the Transmitter has been programmed into. To exit the Program Mode prior to activating the Transmitter, push and release the Receiver bypass button. If the Transmitter is not activated for thirty (30) seconds once the Receiver is in Program Mode, the Receiver will return to Sensor Bypass Mode. Test The Test Mode allows for the installation site to be tested for signal reception. Once in Test Mode, the Transmitter will send a signal to the Receiver at one half the normal signal strength. After sending the signal, the Transmitter will return to the Monitor Mode. Typically, this mode is only utilized during installation. Push and hold the Transmitter button for at least four (4) seconds but not longer than 14 seconds. The Transmitter will send a signal at the test mode signal strength. If the Receiver detects the signal, the Red LED will begin flashing for a duration of two and a half (2.5) minutes. Bypass The Bypass Mode allows for the irrigation system to operate independently from the Wireless Rain Sensor. Regardless of whether the Wireless Rain Sensor is in the Watering Suspended state due to rain or freeze, the irrigation system will operate normally when in the Bypass Mode. You can toggle back and forth between Bypass and Non-Bypass. A Bypassed state with Watering Suspended will reset back to the Monitor Mode once the disks dry out. Momentarily push and release the Receiver button to toggle between the Bypass and Monitor Modes. The Receiver is in Bypass Mode when the Green LED is solid. Note: If the Receiver button is depressed longer than four (4) seconds prior to releasing, the Receiver will enter the Program Mode. 10 WRS Wireless Rain and Freeze Sensor WRS Wireless Rain and Freeze Sensor Receiver LED Indications Normal – ALL LEDs OFF Watering Suspended (Freeze or Rain) – RED SOLID LED The Red LED becomes solid if the Transmitter is activated while the Receiver is in the Bypass or Monitor Mode. No Signal – YELLOW SOLID LED The Transmitter retransmits its current state several times a day. If the Receiver does not receive two consecutive transmissions, then the Yellow LED becomes solid to indicate a loss of signal. The LED will turn off if the Transmitter becomes activated. Possible causes include low batteries, radio frequency interference, and physical obstacles. Sensor Bypass – GREEN SOLID LED The Green LED becomes solid if the Receiver is put into the Bypass Mode. Until a change of state is received from the Transmitter or the user toggles the Receiver back to Monitor Mode, the irrigation system will operate independently from the WRS. Test Mode – RED FLASHING LED The Red LED flashes when the Receiver has successfully received the test signal from the Transmitter. Once the test signal is received, the Receiver will continue to flash the Red LED for two and a half (2.5) minutes. The flashing LED will turn off if the Receiver changes mode. Low Battery – YELLOW FLASHING LED The expected life of the battery is 3 years. The yellow LED begins to flash when approximately two and a half years of battery life have been depleted. Changing the batteries will reset the low battery indicator. Program Mode – GREEN FLASHING LED When the Bypass Switch on the Receiver is held for more than three seconds, the Green LED will begin to blink rapidly. If the button is then released, the Receiver will enter the Program Mode, which is indicated by the Green LED blinking approximately once per second. The Green LED will turn off if the Receiver Bypass Switch is pushed again or the Transmitter becomes activated.
