Weatherproof Line Voltage Thermostats Protect Water from Freezing

Weatherproof Line Voltage Thermostats for freeze settings

Weatherproof line voltage thermostats in freeze settingsOur NEMA 4X weatherproof line voltage thermostats are commonly found in outdoor settings such as de-icers! The thermostat controller measures air temperature to turn on a de-icer when the temperature falls below a set point (0°F-80°F), which keeps the water moving to prevent it from becoming a solid.



Simply plug the power cord from the controller to a grounded 120V outlet, set the temperature you wish the de-icer to come on using the dial, and plug the de-icer into the controllers piggyback plug. When the ambient air temperature falls to the desired set point the thermostat turns the de-icer on. When temperature rises +3° above the set point, the thermostat will automatically turn the de-icer off. De-icer manufacturers recommend setting the dial at 30°F to kick on the equipment when air temperature is below freezing.

De-icers move warm water from the bottom of a pond, lake, etc. creating an ice-free space around boats, docks or other water. In addition to protecting personal property, the thermostat helps protect fish and other aquatic animals. For more information about de-icers, check out a video here!

Portable PreWired Thermostat

Line voltage thermostats uses a liquid-filled sensing element and capillary. There is an exposed or concealed set point dial with adjustable differential, and it will switch line voltages.

K-Kontrols offers both a single stage, heating or cooling, temperature control and a two stage. The two stage line voltage thermostat has two single pole, double throw switches that uses a liquid filled sensing element and capillary.
