The Single Stage Line Voltage Thermostat is great for direct control of de-icers and other outdoor equipment during the colder months to prevent freezing. The line voltage freeze protection thermostat measures air temperature to turn on equipment when the temperature falls below a set point (0F-80F). Most manufacturers recommend setting the dial at 35F to power on the equipment before the air temperature drops below freeze levels. A graduated temperature control unit that can be used anywhere! Clear cover protects from weather and damage. Weatherproof and corrosion proof with all polycarbonate thermoplastic construction and stainless steel capillary sensor. Not effected by surges and lightning strikes or power outages like a digital thermostat.The Single Stage Line Voltage Thermostat uses a liquid-filled sensing element and capillary. There is an exposed or concealed temperature set point dial, and it will switch line voltages.Original equipment manufacturers & agricultural communities worldwide use temperature controls designed & manufactured by K-Kontrols.
