The ETI GIT-1 Gutter Ice Sensor is for use in an automatic ice melting or de-icing control system for gutters and downspouts employing an APS- 3B or APS-4 Control Panel. Heaters operate only while required thus saving energy and ensuring reliable ice melting / de-icing. Since the GIT-1 mounts in gutters and downspouts it senses actual environmental conditions. This improves sensing accuracy. Solid state moisture and temperature sensors provide the sensitivity required for effective automatic control.
The ETI Git-1 is also resistant to ice bridging. Ice bridging can occur if incomplete melting exists near the heater or sensor-- thus leaving an air space which serves as an insulator and prevents effective heater and sensor operation. The GIT- 1's unique microcontroller design frees its moisture sensor from ice bridging. Additional features prevent heater operation under conditions favorable to heater ice tunneling. Low voltage operation simplifies installation.
