1. Description

1.1 Intended Purpose

The electronic control unit EMDR-10 is specifically designed for the control of gutter heating
systems. Depending on outdoor temperature and moisture in the gutter the heating cable will
only be switched on if necessary to ensure a correct drain of the snow water.
