Installs Simply and Easily…
No adjustments necessary
The Freeze-Clik
®
 is designed to install directly to a 
“normally closed” controllerʼs sensor terminals or in 
the common wire circuit between the zone valves and 
the controller with two-conductor wire. No adjustments 
are necessary. If multiple commons are used in the sys-
tem, 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 applications.
Freeze-Clik-Rev – This model designed for 
opposite switching designed to 
turn a device on when tem-
peratures approach freezing 
(example: to protect vegetation 
from a damaging freeze).
Note:  The Freeze-Clik is not designed for crop protection
Accurate Shutoff Before Water Turns to Ice…
Reduces liability hazards for walkways and 
roadways by preventing icing
Accurate, epoxy sealed temperature-sensing element 
automatically stops system water flow at near freez-
ing 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. 
Reducing or eliminating this concern is important to 
any irrigation installer. With the Freeze-Clik installed 
in the system, running 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 installation within 
25 feet of the controller. When contractors go out to the 
job site with the Freeze-Clik, they donʼt have to worry 
about forgetting the wire, making the installation fast 
and easy! 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
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.
INSTALLATION 
INSTRUCTIONS
Note:  Both the standard Freeze-Clik and the Freeze-Clik-
Rev (a “reverse” model where instead of switching 
system operation “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.
