The RM-3 system is housed in an environmentally-sheltered NEMA 4X enclosure to provide various installation options. The RM-3 automatic gutter ice systems are designed for years of maintenance-free operation and can save thousands of dollars in unnecessary repairs, as well as actual loss of use of the building, structure, or facility.

The dual-action GIT-1 sensor detects both moisture and temperature, so the heaters run only when moisture is detected at or below 38°F (3.3°C). The built-in, fixed, 3-hour Hold-On Timer provides for a heating cycle long enough to fully melt snow and ice and keep them from refreezing. The Heater Cycle toggle switch allows manual activation or cancellation of heater operation. The included GIT-1 gutter ice sensor detects ice and snow as moisture at or below 38°F (3.3°C), so the RM-3 system could save hundreds of dollars a year compared to using just a simple thermostat alone to control the system.
