Type 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 heating system will only be activated if a possibility of ice or
snow is indicated by both parameters.
An easily operated encoder button and backlit graphic display ensure quick and easy configuration and
simple indication of temperature, status, etc.
ETO2 is suitable for controlling electric heating cables in 1 or 2 zones. It also features advanced two-
stage output control for economic operation.
