Troubleshooting - Hunter Rain-Clik Product Information

PRODUCT FEATURES
AND BENEFITS
B. Normally Open Sensor Applications
1. A few controllers on the market require a normally
open rain sensor. To attach the receiver to this type
of controller, attach the blue wire and the orange
wire to the controllerʼs sensor input.
C. 24 Volt Solenoid
Valves with Booster
Pump (See Fig. 5)
AC AC
Locate the common
wire to the solenoid
valves and the com-
mon wire leading to
the coil of the relay
that starts the pump.
If these two wires
are connected to the
Line-Out (to Pump)
"common" terminal
Fig. 5
on the controller,
disconnect both of them.
Twist together these two wires along with one wire
from the Rain-Clik™, and secure with a wire nut.
Attach the other wire of the Wireless Rain-Clik™
receiver to the "common" terminal on the controller.
Note: The pump circuit output must be 24 Volts in
this situation. Do not proceed if 110V.
Setting the Transmitter Address
at the Receiver
Units purchased as a kit will already have their address
learned. No addressing is necessary, however if the
receiver or transmitter is replaced, you need to reset
the address.
Each transmitter produced has a unique address
hard-coded into it. A receiver must learn this address
to work with that transmitter. This step will only be
necessary if transmitters and receivers are purchased
separately.
1. Prior to applying power (yellow wires) to the
receiver, press and hold the pushbutton on
the receiver.
2. While the pushbutton is being held apply power
to the receiver–the receiverʼs "sensor status" LED
should light up yellow indicating the receiver is
ready to learn an address.
3. Push and hold the Quick Response™ post on the
transmitter/sensor.

4. Within 4 seconds, the receiverʼs "sensor status"
LED should turn red.
5. Release the transmitter/sensorʼs quick response
post and within 4 seconds the LED on the receiver
should turn green. The address is now learned and
will be retained even in the event of a power outage.
Operation
The receiver has two LEDs, which indicate the state of
the system. The STATUS LED will be RED when 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 this LED is lit,
the rain sensor is bypassed and watering will always
be allowed. Even though the sensor is bypassed, the
STATUS LED will continue to alert you of the state of
the sensor (Wet or Dry).
Battery Life: The Wireless Rain-Clik transmitter
is designed to work daily for up to 10 years with the
maintenance-free battery. The sealed unit is available
as a replacement part. Should you need to change the
transmitter the receiver will have to learn the new
transmitter address.

TROUBLESHOOTING

There is no required maintenance for the unit. The
Wireless Rain-Clik does not have to be removed or
covered for "winterizing" purposes.
Follow 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 receiver and check all wire junc-
tions.
C. Verify temperature (for Rain/Freeze-Clik installa-
tions).
System will not shut off even after heavy rainfall:
A. Check wiring for correctness (see section on wiring
to your irrigation system).
