Outdoor Temperature Control

ETO2 is an electronic controller for fully automatic, economical ice and snow melting on outdoor surfaces and in gutters. Ice forms due to a combination of low temperature and moisture. ETO2 detects both temperature and moisture, and the ice and snow melting system will usually only be activated if ice or snow is present.

As soon as moisture is detected in conjunction with low temperature, the ETO2 controller activates the snow-melting system. Once the sensor has dried out, the thermostat immediately goes into afterrun and the system continues to provide heat for a set time.

The snow melting system is only energized when the outdoor temperature drops below the selected setting and snow or ice is detected by the sensors. Energy is thus only used when absolutely needed.

For gutters - ETO2-4550, ETOR-55 and ETF-744/99
The ETOR sensor is designed for installation in gutters, downpipes, etc. ETOR sensors detect moisture, while ETF sensors measure temperature.
For outdoor surfaces - ETO2-4550, ETOG-55 and ETOG-56/ETOK-1
The ETOG sensor is designed for embedding in the surface of the outdoor area. ETOG sensors measure ground temperature and moisture. The ETF-744/99 sensor can be used for measuring rapid temperature drops.
