INTRODUCTION
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.
