introduction

Type EM 50-2 is an electronic controller for fully automatic, eco-
nomical ice and snow melting on outdoor areas and in gutters. EM
50-2 detects both temperature and moisture and the heating system
will only be activated if a possibility of snow or ice is indicated by
both parameters.
An easily operated encoder button and backlit graphic display en-
sure quick and easy configuration and simple indication of tempera-
ture, status, etc.
EM 50-2 is suitable for controlling electric heating cables in 1 or 2
zones.
