Installation
Connecting Valves and Transformer
Route control wires between the control valve location and the controller using 18 AWG multi-wire sprinkler cable. Attach the common wire (typically white) to one solenoid wire of the valve and a separate control wire to the remaining solenoid wire, noting the color for each station. Secure wires with waterproof connectors.
Open the wiring compartment door to access the terminal strip. Feed valve wires through the cabinet base or conduit. Strip 1/4 inch of insulation from wire ends.
Connect the white valve common wire to the "C" terminal. Connect color-coded wires to their respective station numbers. Route transformer cable through the bottom hole and connect wires to the "AC" terminals. Do not plug the transformer into the power source until the controller is mounted and valves are connected.
Connecting the Battery
Connect a 9-volt alkaline battery (not included) to the battery wire clip for programmable memory backup during power failures. The battery does not activate valves; electrical power must resume for watering.
Connecting a Master Valve
If a master valve is installed, attach its common wire to the "C" terminal and the control wire to the "MV" terminal.
Connecting a Pump Start Relay
If a pump start relay is installed, route its wires into the controller. Connect the common wire to the "C" terminal and the other wire to the "MV" terminal. Mount the controller at least 15 feet (4.5m) away from the relay and pump. Use a jumper wire from an unused station terminal to a station terminal with a control valve to prevent pump damage during power failures.
Connecting a Weather Sensor
Connect a rain sensor (e.g., Hunter Mini-Clik®) by routing its wires through the valve wiring opening. Connect one wire to the "RS" terminal and the other to the "C" terminal. Connect the valve common wire from the field to the "RS" terminal.
Programming
The SRC Controller is easy to program using the dial and display. The display shows time and day when idle, and programming information when the dial is rotated. Flashing portions of the display can be changed with buttons. A reference label inside the door provides instructions.

Installation and Programming
Smart Port® Wiring Harness
The SRR system requires the SRR SmartPort® wiring harness for communication. Installation instructions are included with the SRC manual. Additional harnesses can be purchased.
Installing the SRR Remote Wiring Harness
Install a 1/2" female threaded "Tee" in the field wiring conduit. Feed the red, white, and blue wires through the "Tee" and into the controller's wiring compartment. Screw the harness housing into the "Tee." Attach the wires to the controller's terminal block.
Extending the Wiring Harness
Extending the wiring harness may cause errors or malfunction due to radio interference. Use shielded cable (like Hunter's SCWH) for extensions to minimize electrical noise.
Transmitter: Preparing the Transmitter for Use
The SRR system works out of the box. For customization, read the following steps. Note any changes made, as the transmitter reverts to original settings after battery replacement.
Installing the Transmitter Battery
Install a 9V alkaline battery by sliding open the battery door on the back of the transmitter.
Changing the Transmitter Address
Addresses are used for communication between transmitter and receiver. Factory default is 0. Change address (0-127) for security. To change: Power transmitter, simultaneously press and buttons until "RUN TIME" displays and blinks. Press "ON" button to illuminate "ADDRESS" and blink the address. Use or buttons to set the address. Wait 5 seconds for settings to save.
Receiver: Preparing the receiver for use
To "learn" a new transmitter address, hold the receiver's single button while plugging it into an active wiring harness. The receiver will beep 4 times. Release the button. Press the transmitter's "ON" or "OFF" button. The receiver will beep 4 more times, indicating it has learned the address.
Run Time Adjustment
Adjust the station run time via the transmitter (does not affect controller programming). To change: Power transmitter, press and buttons until "RUN TIME" displays and blinks. Use or buttons to set run time (1-30 minutes). Wait 5 seconds for settings to save.
Activating a Station with the SRR Remote Control System
Plug the receiver into an active wiring harness and wait for 2 beeps. If transmitter is off, power it on. Use or buttons to display the desired station/program. Press "ON" to start. The transmitter will display "TRANSMIT." Press "OFF" to turn off a station. The SRR system turns one station on at a time.
Changing the Maximum Station Number
Factory default is 9 stations. To change: Power transmitter, press and buttons until "RUN TIME" displays and blinks. Press "ON" twice to illuminate and then un-illuminate "ADDRESS." Use or buttons to set the maximum station number (1-48). Wait 5 seconds for settings to save.
Maximizing Operating Range
Factors influencing range include: avoiding metal sources (power meters, pipes), installing the outlet higher up, pointing the receiver antenna vertically, and holding the transmitter vertically facing the receiver.
A Word About Range
Range depends on terrain, obstructions, signal strength, and receiver sensitivity. Hunter designs the SRR transmitter for maximum FCC-allowed power and uses a superior receiver method for reliable operation.
Troubleshooting Guide
| Problem | Causes | Solutions |
|---|---|---|
| Transmitter display is blank | Transmitter is off; Battery is dead | Press any button for 1 second; Replace battery. |
| Cannot access all stations | Maximum station number is set wrong | See "Changing the Maximum Number." |
| Receiver doesn't beep twice after plugging in | SmartPort® not connected properly; Controller has no power | Recheck SmartPort® wiring; Check controller power. |
| Receiver beeps twice but won't respond | Receiver and Transmitter addresses don't match | Relearn address at receiver. |
| Transmitter display stays on | Transmitter will turn off automatically after 5 minutes of inactivity | Wait approximately 5 minutes without pressing buttons. |
| "ERR" message in controller display | SmartPort® wiring leads extended, receiving radio interference | Replace extended wire with shielded cable (Hunter SRR-SCWH). |
| Receiver does not receive signal at close range | Mismatch of addresses in transmitter and receiver | Reset address of receiver. |
| Remote has short range | Interference causes | See "Maximizing Operating Range" and "A Word About Range." |
