INSTALLATION CARD
Introduction
Your new wired Rain-Clik sensor 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 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 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
(Figure 1), 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.
Standard Mount
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 (Figure 2).
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 3).

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:
If the extension needed is: 8–15 m
Wiring to Your Irrigation System
IMPORTANT: The Rain-Clik has 8 m of cable attached to it. These leads
will be wired to the SEN terminals or SEN and SEN COM terminals of the
controller. The order in which they are wired does not matter.
(Figure 2). Remove the jumper from the two SEN terminals.
