All heated Snow Shield de-icing systems are supplied with an automatic local controller which interfaces with a moisture sensor and Thermistor to monitor precipitation and temperature. This system provides the user with a versatile, yet inexpensive method of controlling the de-icing system. These systems were designed specifically to operate in high noise, low temperature environments, for added reliability.
