03 06 10 12 17 Section 1 : INTRODUCTI ON Thank you for selecting a Hydro-Rain® Wireless Rain/Freeze Sensor (HRC-100-RS-RF). This Hydro-Rain® Sensor provides conservation, convenience, and flexibility to your fully automatic watering system. After a set amount of rain has fallen, the sensor will send a wireless signal to the receiver and prevent the timer from watering.
Section 1 : INTRODUCTI ON 1. Manual Test Stem 6. Pushing downward on stem tests transmitter communication with the receiver. Re 2. Rain Fall Adjustment Cap 7. Range adjusts from ¹⁄8" to 1" (3mm to 25mm). This setting will prevent watering when rainfall reaches the specified setting. Fu 3. Vent Ring Se An adjustable ring is designed to control the rain delay duration. 4. Communication Antenna LE 1 Transmits a wireless signal (up to 200') to the rain/freeze receiver. 5.
r. g Section 1 : INTRODUCTI ON 6. Communication Antenna Receives wireless signal from the rain/freeze sensor. 7. Manual Override Button Functions in two ways: 1. Stops timer from watering 2. Allows watering when rain/freeze sensor is active See Manual Override (Section 4) for additional detail LED Panel Lights Located on the receiver, the LED lights communicate the current status of the sensor. (See Figure 2) 6 8. Sensor Override LED Indicates when manual override is on (see manual override above).
Section 2 : INSTALLATION INSTRUCTIONS Mounting the Receiver 1. Select a location within 6” adjacent to your sprinkler timer (receiver may be located indoor or outdoor). 2. Mount rain/freeze receiver (antenna side up) using screws provided. 3. Extend and straighten the antenna upward. 3. aw (Se 4. co 5. Wiring the Receiver to Timer Important: This sensor is designed for 24-Volt irrigation timers only. Do not connect the receiver to 120/240 VAC. All wiring must conform to applicable local codes.
al n al , Section 2 : INSTALLATION INSTRUCTIONS 3. Disconnect the common valve wire from the timer, and attach it (using a wire nut) to the yellow (normal closed) wire from the rain/freeze receiver. (See Figure 4) 4. Connect the white (common) wire from the rain/freeze receiver to the common terminal of the timer. 5. Connect the (2) red “24V” wires to the 24V terminals of the timer.

Section 3 : OPERATION CHECKS Verify Correct Wiring M Select a sprinkler station/zone that is visible and in reach of the rain/freeze receiver and sprinkler timer. After manually activating the station/zone, on the sprinkler timer, press the “Manual Override” button on the receiver. The top light should indicate that the system is being overridden. If the light does not illuminate, check the red wire connections.
s n n d s g Section 3 : OPERATION CHECKS Mounting the Transmitter Mount the rain/freeze sensor to a gutter with the provided thumb screw, or to a flat surface, with provided screws, where it will be exposed to direct, unobstructed rainfall (but away from sprinkler spray). The test stem must be upright. Note: The distance that the transmitter and receiver will operate at is approximately 200 feet line of sight. This distance may be affected by obstacles such as walls, automobiles, metal siding, etc.
Section 4 : ADJUSTMENTS AND OPERATION co mo loc de Fr Th an sw Figure 6: Attaching sensor/transmitter to gutter or flat surface M Rain Sensor The rain sensor keeps the irrigation system from starting or continuing after rainfall quantities of ¹⁄8", ¼", ½", ¾", or 1". We recommend that the sensor be set at the ½" setting. To adjust to the desired quantity of rainfall, rotate the cap on the switch housing so that the pins are located in the proper slots.
e s - Section 4 : ADJUSTMENTS AND OPERATION completely or partially cover the ventilation holes, the hygroscopic discs will dry more slowly. This adjustment can compensate for an “overly sunny” installation location or peculiar soil conditions. Experimenting with the vent rings will best determine the ideal vent setting. (See Figure 7) Freeze Sensor The temperature at which the freeze sensor is activated is 37°F ±2° (3°C ±1°) and is not adjustable.
Section 4 : ADJUSTMENTS AND OPERATION Running the Sprinkler Timer when Rain/Freeze Sensor is Active (see Figure 8) 1. Make sure “Active Sensor” is the only LED illuminated (on the rain/freeze receiver). 2. Push the “Manual Override” button–“Sensor Override” LED will illuminate and “Active Sensor” LED will turn off. 3. To restore rain/freeze sensor function push “Manual Override” again– “Sensor Override” LED will turn off. Stop Sprinkler Timer from Watering (see Figure 9) 1.

Section 5 : MAINTENANCE AND TROUBLESHOOTI NG Maintenance The two lithium 3V batteries (CR2032) will need to be changed as needed. There is a low battery indicator light on the receiver that tells you when you need to change the battery. To change the batteries, remove the black rubber cover from underneath the sensor/transmitter. The battery mount should drop down, attached with a wire. Replace both batteries, making sure the + side of the batteries point to the + indicated on the mount.
Section 5 : MAINTENANCE AND TROUBLESHOOTI NG Sp C. Toggle the manual override switch on the receiver to change status. D. If you have a timer with built-in sensor terminals there is usually a bypass switch located near the terminals, check that the switch is set to “ON.” E. Check that the temperature is at least 39°F (4°C) or higher. System Will Not Shut Off Even After Heavy Rainfall: A. Check wiring for correct installation (See “Operation Checks: Verify Correct Wiring”). B.
