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
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 38˚F (3.3˚C) while moisture is
present. Operation continues a period of time
thereafter to insure complete melting. While
operating, the heaters are maintained at a
nominal temperature of 38˚F (3.3˚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.
