ETI GIT-3A Automatic Gutter Ice Melting Control
Snow and ice on a roof cause a variety of expensive problems including gutter and down spout breakage and interior water damage. In addition, falling ice can endanger pedestrians. Using heating cables for ice melting can eliminate these problems, however uncontrolled heating is expensive and not energy efficient.
The computerized patent pending GIT-3A Automatic Gutter Ice Melting Control operates ice melting heaters only while required thus insuring energy efficiency and low operating costs. A GIT-3A consists of a gutter-mounted sensor and a control enclosure connected by a 12' 6" (3.8 meter) cable. If the distance between the sensor and control needs to be changed, please contact Customer Service.
The GIT-3A senses both moisture and temperature conditions in the gutter or down spout thus assuring optimum control. Ice melting heaters operate at temperatures at or below 38º F (3.3º C) while moisture is present. Operation continues a period of time there- after to insure complete melting. While operating, the heaters are maintained at a nominal temperature of 38º F (3.3º C).
Line voltage and ice melting heater connections are located in the control enclosure. The GIT-3A operates from single-phase 120, 208/240 or 277 volt supply selected by an internal jumper connection that is set during installation. It controls single-phase ice melting heater loads of up to 26 amps. The GIT-3A meets the new NEC Class 2 low voltage requirement for wet locations. It is both UL and CUL Listed. Safety testing was done to UL Standard 873.
