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.
If the best location for temperature sensing 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.
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.
