The simplest, most effective way to pre-
vent an irrigation system from operating
during or after inclement weather is to
use the Hunter Weather Sensor Devices.
Easily installed on any automatic irrigation
system, the Weather Sensors shut sprin-
klers off during rain, wind, sleet, and
freezing temperatures. These sensors are
designed to automatically reset without
ever affecting the irrigation system con-
troller. Built to withstand the harshest
conditions, there’s no better way to ensure
that your system isn’t watering when it
shouldn’t be. When you are concerned
with water waste, Hunter’s sensing devices
backed by a 5-year warranty, need to be a
part of your irrigation system.

MINI-CLIK
RAIN SENSOR
The World’s Most Simple,
Accurate, Rugged and Reliable
Rain Sensor
In most installations, the Mini-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
activating and allowing water to flow.
The Mini-Clik Rain Sensor automat-
ically compensates for the amount of
rainfall that occurred before reactivating.
Hydroscopic disks absorb water and then
expand proportionally to the amount of
rain that fell. As the moisture-laden disks
expand, they activate a switch that inter-
rupts the electrical circuit from the control-
ler to the valves. Once the Mini-Clik has
dried sufficiently, the switch closes again
to allow for normal operation. The time
it takes the Mini-Clik to reset for normal
sprinkler operation after the rain has
stopped is determined by weather condi-
tions such as sunlight, wind, humidity, etc.
These conditions will determine how fast
the discs dry out. The irrigated turf also
experiences the same conditions. So when
the turf needs more water, the Mini-Clik is
already reset to allow the sprinkler system
to go at the next scheduled cycle.

Easily Installs on any Automatic
Irrigation System…
Simple to add on to an existing or new
installation.
The Mini-Clik is versatile enough to work
with all popular irrigation controllers. The
Mini-Clik is available in two versions or
SKU’s. One is wired for “normally closed”
sensor terminals and the other is wired for
“normally open” sensor terminals. Each
unit will have two wires attached to it, con-
nected to a 25-foot extension.
If the controller has a sensor bypass
switch or dial setting, then both extension
wires will be connected to the controller
sensor terminals. If the controller does not
have a sensor bypass switch or a dial set-
ting, then one extension wire is connected
to the controller common terminal and the
other extension wire is connected to the
common wire(s) from the field.
Available in 24 Volt and 110/220 Volt UL
Listed Models…
Four different models to accommodate
your particular wiring needs.
Mini-Clik – The standard “normally
closed” Mini-Clik model for use on most
24 volt applications.
Mini-Clik-NO – The standard “nor-
mally open” Mini-Clik model for use on
most 24 volt applications.
Mini-Clik-C – Features a ½" female
threaded inlet at the bottom to accommo-
date conduit.
Mini-Clik-HV – The C model with
added code approved liquid-tight electrical
fittings for 110/220 volt wiring applica-
tions and systems using pumps drawing
less than 10 amps peak. Also includes 18
inches of 16 AWG wire. Ready to mount
on any standard junction box.
PRODUCT FEATURES
AND BENEFITS

Mini-Clik Rain Sensors
Constructed of High Impact
Thermoplastic…
Dependable operation built to last.
The Mini-Clik is constructed
of heavy-duty materials
including a thermoplastic
that can withstand all
extremes of weather from
direct scorching sun to freez-
ing ice storms.
Maintenance-Free Patented
Sensing Mechanism…
No callbacks, set it and forget it.
Unlike other rain sensors that use collec-
tion cups, the Mini-Clik does not collect
debris, so it does not require cleaning.
And, for those in cold climates, the
Mini-Clik does not have to be removed or
covered for “winterizing” purposes. This
means no required maintenance for the
unit and no callbacks to clean it.
The sensing mechanism is ingenious
but simple. Disks absorb water and then
expand proportionally to the amount of
rainfall that fell (e.g., a small cloudburst
would result in little absorption, a thun-
derstorm with 2" of rainfall would lead
to more absorption and thus more expan-
sion). As the moisture-laden disks expand,
they eventually activate a switch that inter-
rupts the circuit from the controller to the
valves. As the disks dry out, they contract
and release the switch.
5 Year Warranty…
Hunter Industries backs up its products.
A full five-year warranty by Hunter
communicates to our customers that the
Mini-Clik is a rain sensor that stands up
to the environment. The end-user can be
assured of a quality product with a guaran-
tee of dependable operation.
Adjusts To Actuate At Various
Rainfall Quantities…
Versatile and accurate.
Depending on local conditions, the
Mini-Clik can keep the irrigation system
from starting or continuing after rainfall
quantities of 1/8", ¼", ½", ¾", 1" (3 mm,
6 mm, 13 mm, 19 mm, 25 mm). To adjust
it to the desired shutoff quantity, rotate the
cap on the switch housing so that the pins
are located in the proper slots.

Includes 25 Feet of 20 Gauge Two
Conductor Wire…
Fast and easy mounting out of sight.
Hunter supplies wire needed for instal-
lation within 25 feet of the controller.
Whether you pre-install on poles or install
at the job, with 25 feet of wire already
attached to the Mini-Clik, installation is
fast and easy. When contractors go out to
the job site with the Mini-Clik, they don’t
have to worry about forgetting the wire!
If longer wire runs are needed for installa-
tion, no problem! Just add an extension.
If the extension needed is:
25-50 feet use: 20 gauge
50-100 feet use: 18 gauge
100 feet or more use: 16 gauge

MINI-CLIK INSTALLATION INSTRUCTIONS
In most installations, the Mini-Clik acts as
a switch to break the electrial 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
Mini-Clik has dried
sufficiently, the switch
closes again to allow for
normal operation.
The Mini-Clik has
two blue wires con-
nected to a 25 foot
extension.
For the Model Mini-
Clik-C: This rain sensor
unit is the same as the
standard model except
for the lack of an alumi-
num mounting bracket
and the addition of a
½" threaded cap, which
allows for the easy use
of electrical conduit to totally enclose the
wires. Unless local code states otherwise,
plumbing grade PVC pipe can be used as
well as electrical grade conduit.
For the Model Mini-Clik-HV: This
rain sensor unit is designed to be used
with automatic irrigation systems of two
principle designs: 1) single-station electri-
cal timer (e.g., Intermatic) that switches
power to a pump, either directly or through
a relay; or 2) single-station electrical timer
that switches power to a solenoid valve.
MOUNTING
Standard Model: Using the screws pro-
vided, mount the Mini-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
any angled surface. Loosen the locknut
and screw before swivel-
ing bracket, and then re-
tighten.
For the Conduit
Model Mini-Clik-C:
The conduit acts as the
mounting support for the
unit. Therefore, place
and mount the conduit
to allow for the desired
sensor location as
described in the main
instructions for the stan-
dard model. Be sure to
support the conduit suf-
ficiently along its vari-
ous lengths.
For the High-Voltage
Model Mini-Clik-HV:
The mounting of this
unit is primarily made
by screwing the fitting
end into the threaded
holes of covers to rectangular junction
boxes (for outdoor use) or the covers of
round junction boxes commonly used for
outdoor spotlights. Locate the junction box
so that with the Mini-Clik attached, unob-
structed rainfall will hit the outermost
sensing end of the unit. If a longer reach is
needed, the “Carlon” flexible conduit piece
can be substituted with a slightly longer
piece (up to 8" length with no support or
up to 11" with support).
Helpful hints for mounting:
A. When looking for a suitable location
such as on the side of a building or
post, the closer the Mini-Clik is to the
controller, the shorter the wire run will
be. This will also minimize the chance
for wire breaks.

Mini-Clik Rain Sensors
B. The ideal location for mounting is not
always the most practical location. In
the case where a compromise must exist
(such as low location on a side wall
rather than the preferred high location),
note that the Mini-Clik will still work
as it will always receive some rainfall
– it just will not be as accurate in its
gauging as it could be.
C. As described in the “Operation” section
of this manual, “reset rate” refers to the
amount of time it takes the Mini-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 consider-
ation should extreme conditions exist.
For example, mounting the Mini-Clik
on a very sunny, southern end of a build-
ing may cause the Mini-Clik to dry out
sooner than desired. Similarly, mounting
on the northern end of a building with
constant shade may keep the Mini-Clik
from drying soon enough.
Once the Mini-Clik is mounted, run the
wire to the controller, and fasten it every
few feet with wire clips or stapled for best
results. If an extension to the wire provided
is needed, use the following table to deter-
mine the minimum wire gauge needed:
If the extension needed is:
25-50 feet use: 20 gauge
50-100 feet use: 18 gauge
100 feet or more use: 16 gauge

Coil
Where the timer is controlling a pump,
the relay may be inside the timer, exter-
nal or non-existent. If there is no relay
in the circuit, one must be added. The
wiring for an internal or external relay
is the same: the Mini-Clik breaks the
circuit to the coil of the relay only.
Either wire of the coil may be broken.
Operation Check to Verify Correct Wiring
Turn on one zone of the irrigation system
that is visible while you are in reach of the
Mini-Clik. Manually depress the spindle at
the top of the Mini-Clik until you hear
the switch “click” off. The sprinkler zone
should stop instantaneously. If it does not,
check wiring for correctness. It is not nec-
essary to “wet” test the Mini-Clik, although
it will test the operation fine, if desired.
ADJUSTMENTS AND
OPERATION
The Mini-Clik can keep the irrigation
system from starting or continuing after
rainfall quantities of 1/8", ¼", ½", ¾" or 1".
To adjust it to the desired shut-off quan-
tity, rotate the cap
on the switch hous-
ing so that the pins
are located in the
proper slots (see
Figure 7). Do not
forcibly twist the
cap as this might
break the pins.
The time that it
takes the Mini-Clik to reset for normal
sprinkler operation after the rain has
stopped is determined by weather condi-
tions (wind, sunlight, humidity, etc.) These
conditions will determine how fast the
hygroscopic discs dry out, and since the
turf is also experiencing the same con-
ditions, their respective drying rates will
roughly parallel each other. So when the
turf needs more water, the Mini-Clik is
already reset to allow the sprinkler system
to go at the next scheduled cycle.
There is an adjustment capability on the
Mini-Clik that will slow down the reset
rate. By turning the “vent ring” (see Figure
Mini-Clik Rain Sensors
1/8 1/4
1/2 3/4
1
Figure 7
VentVent Ring

10
®
7) to completely or partially cover the
ventilation holes, the hydroscopic discs
will dry more slowly. This adjustment can
compensate for an “overly sunny” installa-
MINI-CLIK INSTALLATION INSTRUCTIONS (cont.)
tion location, or peculiar soil conditions.
Experience will best determine the ideal
vent setting.
System will not come on at all:
A. Make sure the Mini-Clik is not installed
in the path of any watering from the
system’s sprinklers.
B. Check to see that the
Mini-Clik discs are dry and
the switch “clicks” on and
off freely by pressing the top
of the spindle.
C. Look for breaks in the wire
leading to the Mini-Clik and
check all wire connections.
D. Finally, if the Mini-Clik is
dry and the wire leading to it
is good, check the Mini-Clik
switch by nicking the insu-
lation of the two “outer”
wires near the unit to expose
copper. Turn one sprinkler
zone on, and apply a “jumper wire”
across the two exposed wires. If the
sprinkler now comes on, the switch is
bad. Wrap all nicked wires with electri-
cal tape.
TROUBLESHOOTING THE MINI-CLIK
System will not shut off even after
heavy rainfall:
A. If a Hunter controller is used, check the
dial position. If the dial is on the RUN
(Bypass Sensor) position
the controller will disregard
sensor.
B. Check Bypass Switch posi-
tion. If the switch is on the
BYPASS position the con-
troller will disregard sensor
activity.
C. Check wiring for correct-
ness. Check by depressing
the spindle at the top of
the cap until the switch is
heard “clicking” off. When
the switch “clicks” off, the
sprinkler zone should stop
immediately.
D. Check the sensitivity setting on the
Mini-Clik. If the setting is set for high
rainfall amounts, move the cap to a
more sensitive setting. The Mini-Clik is
an accurate rain gauge and can be veri-
fied by setting up a “tube” type rain
gauge in the same vicinity and making
periodic readings.
E. Is rainfall actually hitting the
Mini-Clik? Check for obstructions
to rainfall such as overhangs, tree
branches or walls.

Mini-Clik Rain Sensors
Q: Two days ago it rained and the sprin-
klers came on this morning, how do I
get them to stay off longer?
A: There is a “vent ring” located just
below the cap that can be closed
or partially closed to restrict airflow
through the Mini-Clik. Make sure
this ring covers the holes on the
Mini-Clik, and it will allow the disks
to dry more slowly, thus keeping
the Mini-Clik shut off longer. This
adjustment can compensate for an
“overly sunny” installation location.
Q: How much water and money can
be saved?
A: The amount saved varies, but in a
temperate climate with average rain-
fall, savings are usually substantial.
There are several factors involved in
determining how much a Mini-Clik
can reduce water usage: how often it
rains, whether or not the controller is
left on for automatic operation, and
the amount of water applied by the
system per cycle.
Basically, if you know the water costs
in your area and how much water is
being applied per watering cycle by
the whole system, then you will know
how much is being saved each time
the Mini-Clik interrupts the sprin-
kling cycle because of rainfall.
FREQUENTLY ASKED QUESTIONS
As an example, take a system that
irrigates 15,000 square feet of turf
and is set to run each zone so that
the equivalent of ¼" of water is
applied per cycle. Volumetric calcu-
lations determine that 2500 gallons
of water are being applied over the
15,000 square feet of turf per cycle.
Using an average water cost table for
the San Marcos, California area, it
costs $3.47/thousand gallons (or, for
our example, $8.68 for the 2500
gallons). Therefore, every time the
Mini-Clik prevents the sprinkling
cycle from proceeding because of
rainfall, $8.68 is saved, and 2500 gal-
lons of fresh water are not wasted.
Multiply this by the number of sub-
stantial rainfalls that occur in your
area over one growing season and
you can see the potential for savings
of money and water. The Mini-Clik
pays for itself in a short time, and the
installed irrigation system is the most
efficient it can be.

Control Irrigation System
Operation During High Winds
The Wind-Clik Wind Sensor acts as a
switch to break the circuit to the solenoid
valves of the irrigation system during
windy conditions. This allows the timer
to advance as scheduled, but stops the
valves from activating (not allowing water
to flow). Once the wind conditions drop
below the reset point, the switch closes
again to allow for normal operation. The
Wind-Clik can be used in conjunction with
other sensors to enhance the overall auto-
mation of any irrigation system. Mount
the unit in an area that receives prevailing
winds without hindrance.
Installs Simply and Easily…
No adjustments necessary.
The Wind-Clik is designed to
install directly to a “normally
closed” or “normally open” con-
troller’s sensor terminals or in the
common wire circuit between the
zone valves and the controller.
If multiple commons are used in
the system, the Wind-Clik must
be tied in to the end of all the
common wires, then connected to
the controller. If the Mini-Clik or
Freeze-Clik is already installed or
is to be part of the system, the
Wind Sensor is to be wired in series with
the other sensors so either or both devices
can control the circuit.
Designed for “Normally Closed” or
“Normally Open” Operation…
Versatile to meet the needs of
all controllers.
The type of controller used on the job
will not be a concern for the installer
because the Wind-Clik is designed to work
with either “normally closed” or “normally
open” sensor circuits. The unit comes
from Hunter with three colored wires
attached ready for installation. Depending
on what the controller sensor circuitry is,
the installer will hook up the green and
red wires for “normally closed” and hook
up the green and blue wires for “normally
open” systems.
Adjustable Shutoff for Wind Speeds
Between 12 and 35 mph…
Effectively control irrigation system
operation during windy conditions.
A simple turn of the side adjustment on the
Wind-Clik allows the irrigation system to
shut down between wind speeds of 12 and
35 mph. Wind speeds often vary according

to ground height, so for irrigation system
control, the wind speed about 6 feet above
the ground would be a good representative
height for the Wind-Clik placement.
Automatic Reset of System at Wind
Speeds From 8 To 24 mph…
Select the setting that is best for your area.
A feature just as important as a shutoff
speed is the reset speed. This is the speed
that the wind will have to slow down to
in order to reset the switch. The Wind-Clik
allows the user to adjust a reset speed
between 8 and 24 mph with a turn of the
side adjustment.
Automatic Damping Feature…
Eliminates erratic system
operation due to gusty winds.
The built-in damping feature
allows for short wind gusts to
occur without affecting the per-
formance of the system, thus
keeping the system from repet-
itively shutting on and off.
Therefore, the wind speed set-
tings, while accurate under con-
trolled conditions, are actually
relative averages when set up in
the field.
Reduces Liability Hazards of Wet
Walkways and Roadways…
Wind-blown water will no longer be a
safety concern.
Today, with litigation a prominent factor in
how business is conducted, reducing lia-
bility hazards of wet sidewalks and road-
ways in our landscapes is something
Hunter takes seriously. With the Wind-Clik
installed in the system, wind blown water
is not an issue. Irrigation water should set
down where it was designed to land.
Cut Down on Overspray When Used With
Fountains…
Keep surrounding areas safe and dry.
A common non-irrigation related instal-
lation of the Wind-Clik is utilizing the
product with fountain systems. With a
quick adjustment of the dial water can be
stopped from blowing outside the fountain
containment area where doesn’t belong.

WIND-CLIK INSTALLATION INSTRUCTIONS
In most installations, the Wind-Clik acts as
a switch to break the circuit to the solenoid
valves of the irrigation system during high
wind conditions. This allows the timer
to advance as scheduled, but keeps the
valves from opening the water flow. Once
the wind conditions drop below the reset
point, the switch closes again to allow for
normal operation. This is performed by the
wind action of the vanes. They rotate about
180°, and DO NOT SPIN. There are arrow
indicators on the top part of the housing
that indicate the direction of rotation from
rest. The switching action occurs about
midway in the range of rotation.
MOUNTING
The housing of the Wind-Clik is designed
to slip over the end of 2" PVC pipe. The
length and the fixing of the pipe is then
up to the user depending on the situation.
For example, the pipe could be inserted
directly into the ground as a post, or
a short length could be screwed into a
wooden deck post.
Mounting Location
Wind obstructions should be avoided,
of course; however, when buildings are
nearby, the Wind-Clik should be located
so that the prevailing wind direction is not
obstructed. Going up high is not always
necessary; however, it is a good way
to avoid obstructions. Wind speeds often
vary according to ground height, and
for irrigation system control the wind
speed about 6 feet above ground would
be a good representative height for the
Wind-Clik placement.

The Wind-Clik connects directly to the
ICC. This allows you to easily over-ride
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 (See Figure 2).

a controller with sensor inputs, use either
the N.C. or N.O. wire depending on the
controller’s instructions (See Figure 4).

ADJUSTMENTS
The large knob is the switching (actuation)
speed in mph. For example, if the unit
is wired “normally closed,” the dial will
indicate the wind speed that the unit will
switch open. The small knob is the reset
speed. This is the wind speed that the wind
will have to slow down to in order to reset
the switch (closed, in this example). The
reset speed should always be set lower than
the switching speed. If the reset speed is set
the same or higher than switch-ing speed,
extreme switch chatter could occur (on-off-
on-off etc). The difference between the two
settings will largely determine the cycling
of the system being controlled. The larger
the difference, the longer the cycle. Do not
try to move the dial knobs counter-clock-
wise past the lowest speed setting, nor go
past the highest speed setting.

OPERATION
There is built in damping in the unit
to alleviate the problem of short gusts
of wind. Therefore, the wind speed set-
tings, while accurate under controlled con-
ditions, are actually relative averages when
set up in the field. The user should
make initial wind speed settings and then
observe to make sure the Wind-Clik is
switching as desired. Incremental adjust-
ments can then be made. Manual operation
or testing of the unit can be done by manu-
ally rotating the vanes in the direction of
the arrows. Switching will occur about 90°
from the rest position and stay switched to
the end of its travel range (180° from rest).
Allowing the vanes to rotate backwards to
the rest position will deactivate the switch
(about 45° from the rest position).

FREEZE-CLIK
FREEZE SENSOR
Control Irrigation System
Operation During Freezing
Temperatures
In most installations, the Freeze-Clik
Sensor acts as a switch to break the circuit
to the solenoid valves of the irrigation
system near freezing. This allows the timer
to advance as scheduled, but stops the
valves from activating not allowing water
to flow. Once the low temperature period
climbs above 37°F (3°C), the switch closes
again to allow for normal operation.

Installs Simply and Easily…
No adjustments necessary.
The Freeze-Clik is designed to install
directly to a “normally closed” control-
ler’s sensor terminals or in the common
wire circuit between the zone valves and
the controller with two-conductor wire.
No adjustments are necessary. If mul-
tiple commons are used in the system,
the Freeze-Clik must be tied in to the
terminus of all the common wires, then
connected to the controller.
Available in 24 Volt Standard and Reverse
Switching Models…
Two different models to accommodate your
particular wiring needs.
Freeze-Clik – The standard Freeze-Clik
model for use on most 24 volt applica-
tions.
Freeze-Clik-Rev – The 401R model
designed for opposite switching designed
to turn a device on when temperatures
approach freezing (example: to protect
vegetation from a damaging freeze)
Note: The Freeze-Clik is not designed for
crop protection
PRODUCT FEATURES

Accurate Shutoff Before Water Turns
to Ice…
Reduces liability hazards for walkways
and roadways by preventing icing.
Accurate, double-epoxy sealed
temperature-sensing element
automatically stops system
water flow at near freezing
temperatures and resets system
when temperatures rises above
the set point of 37°F (3°C)
(+/- 2°C).
Reduces Liability Hazards
of Iced Walkways and
Roadways…
“Wayward” water that freezes
over is never a safety issue.
Water from irrigation systems
that lands on pavement and freezes over
can create serious liability hazards. Reduc-
ing or eliminating this concern is impor-
tant to any irrigation installer. With the
Freeze-Clik installed in the system, run-
ning water that freezes on traffic areas is
not an issue.
Includes 25 Feet of 20 Gauge Two
Conductor Wire…
Fast and easy mounting out of sight.
Hunter supplies wire needed for installa-
tion within 25 feet of the controller. When
contractors go out to the job site with
the Freeze-Clik, they don’t have to worry
about forgetting the wire, making the
installation fast and easy! If longer wire
runs are needed for installation, no prob-
lem! Just add an extension
If the extension needed is:
25-50 feet use: 20 gauge
50-100 feet use: 18 gauge
100 feet or more use: 16 gauge
Can Be Used in Conjunction With
Other Sensors…
Enhances the overall automation of
irrigation systems.
If the Mini-Clik or Wind-Clik is
already installed or is to be part
of the system, the Freeze Clik
is to be wired in series with the
other sensors so either or both
devices can control the circuit.
5 Year Warranty…
Hunter Industries backs up
its products.
A full five-year warranty by
Hunter communicates to our
customers that the Freeze-Clik
is an irrigation sensor that
stands up to the environment.
The end-user can be assured of a quality
product with a guarantee of dependable
operation.

Note: Both the standard Freeze-Clik and
the Freeze-Clik-Rev (a “reverse” model
where instead of switching system opera-
tion “off” at a set temperature point, the
system is switched “on”) are installed and
wired in the same manner.
The correct placement of the Freeze-Clik
is critical for accurate temperature sensing.
It must be mounted out of direct sunlight,
and where free outdoor air circulation
is possible. Examples would be the
north wall of a building or under eaves
or overhangs.
If the best location for temperature sens-
ing is not a feasible location for mounting
the Freeze-Clik, an alternate location may
be chosen if, in addition, a “sun guard” is
used (a piece of flashing, for example) to
shade the Freeze-Clik during that time of
day that the sun could hit it (see Figure 1)
Figure 1 .
The Freeze-Clik housing is designed so
that it provides the sensing element some
amount of shaded protection from direct
or indirect radiation, while allowing air
to move freely around it. This feature,
along with the best possible placement,
will allow the Freeze-Clik Freeze sensor to
respond at the correct temperature.
FREEZE-CLIK INSTALLATION INSTRUCTIONS
The aluminum swivel bracket allows
angling of the housing away from a ther-
mal mass, such as an uninsulated masonry
wall of a heated structure. The air along
the outer inch or so can be a few degrees
warmer than the actual outdoor air. To
swivel the bracket, loosen the locknut first,
then retighten.
Using the screws provided, attach the
Freeze-Clik to the chosen surface. Run
the extension wire to the controller. If an
extension to the wire is needed, use wire
no lighter than 20 AWG.

Common Wire
Other Controllers
The Freeze-Clik freeze sensor is wired to
the 24 VAC common ground circuit of the
solenoid valves (as shown in Figure 4).
Locate the common ground wire of the
solenoid valves. If it is connected to the
common terminal on the controller, dis-
connect it.
Attach one lead of the Freeze-Clik to the
common terminal on the controller and the
other lead to the common ground wire of
the solenoid valves.
If a Mini-Clik Rain Sensor is already
installed or is to be part of the installation
(see Figure 5), the Freeze Sensor is to be
wired in series with the Rain Sensor so
that either (or both) devices can control
the circuit.

OPERATION
The Freeze-Clik is preset and is not adjust-
able. It will break the common ground cir-
cuit, thereby keeping the sprinkler system
from operating at, or below, 3˚C (37˚F). At
temperatures above 3˚C, it will close the
circuit for normal sprinkler operation.
For Freeze-Clik-Rev Model: The tem-
perature setting works in reverse on this
model with the circuit not allowing oper-
ation of the sprinkler system above 3˚C
(37˚F). Once the temperature reaches this
point or goes below, it will activate the
system and commence watering for what-
ever amount of time you have set on your
controller.
