Hunter Rain-Clik WRC-TR Installation Instructions

INTRODUCTION
The Wireless Rain-Clik™ acts as a switch to break the circuit to the solenoid
valves of the irrigation system when it has rained. This allows the timer to
advance as scheduled, but keeps the valves from opening the water flow. Once
the Wireless Rain-Clik has dried sufficiently, the switch closes again to allow for
normal operation.
The Wireless Rain/Freeze-Clik
®
keep the system from operating at, or below 3°C (37°F). At temperatures above
3°C, it will close the circuit for normal sprinker operation.
CONTENTS
Included with the Wireless
Rain-Clik are the following items:
1. Sensor body with Transmitter
2. Telescoping extension arm
3. Wall mount / Conduit adapter
4. Gutter clip
5. Mounting Hardware
6. Receiver
7. Cover for Receiver
MOUNTING
Standard Mount:
Using the screws provided, mount the Wireless Rain-Clik transmitter on any
surface where it will be exposed to unobstructed rainfall, but not in the path of
sprinkler spray. The switch-housing portion must be upright (as pictured), but
the 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.
Attach the Wireless
Rain-Clik to the gutter
Standard
mounting bracket with the
Mount
screws provided.
Helpful Hints for
Mounting:
A. Choose a location
such as on the side of
a building or post, the
closer the Wireless
Rain-Clik is to the
controller, the better
reception will be. DO
NOT EXCEED 300
feet.
B. Correct placement
of the Wireless
Rain/Freeze-Clik is Gutter
Mount
important for accurate
temperature sensing.
The best location for
mounting would be out
of direct sunlight.
C. As described in the
"Operation" section
of this manual, "reset
rate" refers to the
amount of time it takes
the Wireless Rain-Clik
to dry out sufficiently
for the sprinkler
system to be allowed
to come back on.
Mounting the Wireless Rain-Clik on a very sunny, southern end of a building
may cause the Wireless Rain-Clik to dry out sooner than desired. Similarly,
mounting on the northern end of a building with constant shade may keep
the Wireless Rain-Clik from drying soon enough.
Transmitters/Sensor
• Nothing to set up with this unit after installation
• The unit can be tested stand-alone as follows: press and hold the post on
the quick response section. Within 3 seconds of pressing and holding this
post down, the LED protruding from the potting should blink once. Release
includes a freeze sensor that is designed to

the post, within 3
seconds the LED

again. (Figure 1)
Receiver
• Using the hardware
included, mount the
receiver to the wall
(use included wall
anchors if needed).
Make sure to put the
rubber cover/gasket

under the unit when
attaching it in an
outdoor location.

WIRING TO YOUR IRRIGATION SYSTEM
WARNING! This unit is designed to be installed in conjunction with 24VAC
Receiver Installation, SRC Controller: (See Figure 2)
➆
1. Attach the two yellow
wires to the AC terminals
of the SRC (polarity does
not matter).
2. Attach the blue wire to the
RS terminal.
3. Attach the white wire to
the "C" terminal.
4. Attach the valve common
wire to the RS terminal.
Receiver Installation,
Pro-C and ICC Controllers:
(See Figure 3)
1. Attach the two yellow
wires to the AC terminals
of the controller (polarity
does not matter).
2. Attach the blue wire to
one SEN terminal and
the white wire to the
other SEN terminal of the
controller.
Receiver Installation, Other
Controllers:
A. Normally Closed
Sensor Applications
(See Figure 4)
1. Attach the two yellow
wires to the AC terminals
of the controllers (polarity
does not matter).
2. To attach the receiver
to this type of controller,
attach the blue wire and
the white wire to the
sensor terminals of the
controller, or in-line with
the valve common.
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
controller's sensor input.
