Page: 5 / 32

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.
