Features of ETI GIT-1 Gutter Ice Sensor

The ETI GIT-1 Gutter Ice Sensor is designed to be used with either the APS-3C or APS-4C snow melting controller in roof and gutter deicing applications. Heaters operate only if moisture occurs at temperatures below 38°F (3.3°C), thus saving energy and ensuring reliable ice melting. The sensor mounts directly in the gutter or downspout to sense the actual environmental conditions which improves sensing accuracy.

• Reduces operating cost
• Reliable automatic deicing control
• Senses both moisture and temperature
• Gutter or downspout mounted for accuracy
• Unique design prevents ice bridging
• Rugged housing
• Simple low cost installation
• Field proven reliability
• Can be located up to 2000 ft (609.6m) away from the control panel

Application Information

Ice bridging occurs if incomplete melting occurs near the heater or sensor leaving an air space. The air insulates thus preventing effective heater and sensor operation. The GIT-1s unique microcontroller design frees its moisture sensor from ice bridging. Additional features prevent heater operation under conditions favorable to heater ice tunneling.

An automatic freeze prevention control system for gutters and downspouts employs one or more GIT–1 Gutter Ice Sensors and either APS–3C or APS–4C Control Panel. Heaters operate only if moisture occurs at temperatures below 38°F (3.3°C), thus saving energy and ensuring reliable ice melting. 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.
