INSTALLATION CARD
Introduction
Your new wired Rain-Clik combines optimal performance, water savings, and
installation convenience in an economical rain sensor package.
The wired 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
Rain-Clik has dried sufficiently, the switch closes again to allow for normal
operation. The Rain-Clik is supplied with 25' (8 m) of wiring for installation on
your controller.
Unlike other rain sensors, you do not need to determine the setting for rainfall
shutoff. The wired Rain-Clik is self-adjusting. With Rain-Clik, your sprinkler
system will shut down within the first few minutes of any rainfall. The total
amount of rain received is registered inside the unit and determines how long
your system will stay off. The wired Rain/Freeze-Clik includes a freeze sensor
that is designed to keep the system from operating at or below 37°F (3°C).
At temperatures above 37°F (3° C), it will close the circuit for normal sprinkler
operation. The freeze sensor prevents ice on landscapes, roadways, and
walkways.
Mounting
Standard Model
Using the screws provided within the package, mount the Rain-Clik 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 an
angled surface. Loosen the locknut and screw before swiveling the bracket,
and then re-tighten.
Gutter Mounting
(SGM Sold Separately):
The gutter mount can be purchased
as an optional accessory for your
Rain-Clik (order p/n SGM). The SGM
allows the Rain-Clik to be mounted
directly to the side of a gutter. To
install your Rain-Clik on a gutter,
remove the screw, nut, and standard
metal extension arm supplied with
the Rain-Clik, and reinstall the screw
and gutter mount. Position the
gutter mount on the edge of the
gutter and twist the thumbscrew to
secure it in place.
Helpful Hints for Mounting
A. When looking for a suitable
location such as the side of a
building or post, the closer the
Rain-Clik is to the controller, the
shorter the wire run will be. This
will also minimize the chance for
wire breaks.
B. Correct placement of the Rain/
Freeze-Clik model is important
for accurate temperature sensing. The best location would be out of
direct sunlight (Figure A).
C. As described in the “Operation” section of this manual, “reset
rate” refers to the amount of time it takes the Rain-Clik to dry out
sufficiently for the sprinkler system to be allowed to come back
on. The mounting location will affect this rate and should be taken
into consideration should extreme conditions exist. For example,
mounting the Rain-Clik on a very sunny, southern end of a building
may cause the Rain-Clik to dry out sooner than desired. Similarly,
mounting on the northern end of a building with constant shade may
keep the Rain-Clik from drying soon enough.
Once the Rain-Clik is mounted, run the wire to the controller, and fasten
it every few feet with wire clips or staples for best results. Be careful not
to cut through the wire insulation with fastening hardware or chaff the
insulation when routing wire through or around metal materials (e.g.,
gutter, siding, etc.). If an extension to the wire provided is needed, use
the following table to determine the minimum wire gauge needed:
Wiring to Your Irrigation System
IMPORTANT:
The Rain-Clik is sold and designed for hookup to
24-volt irrigation controllers only.
Wiring to Hunter Controllers
The Rain-Clik connects directly to the controller. This allows you to easily
override the sensor by using the Sensor switch on the front panel.
1. Remove the jumper from the two “SEN” terminals.
2. Route the wires from the rain sensor up through the same conduit
opening used for valve wiring.
3. Connect one wire to the terminal labeled “SEN” and the other wire to
the other “SEN” terminal (Figure 1).
If the extension needed is: 25-50'/8-15 m 50-100'/15-30 m 100'+/30 m
use: 20 AWG/0.8 mm 18 AWG/1 mm 16 AWG/1.3 mm
