Introduction
Type ETR2 is an electronic thermostat for fully automatic, economical ice and snow melting on small
outdoor areas and in gutters. Ice forms due to a combination of low temperature and moisture. ETR2
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. ETR2 is suitable for controlling electric heating cables.
Glossary
TEMP SET Allows the temperature at which heating is to be activated to be set.
TIME SET Allows the afterheat duration to be set, i.e. the length of time the system is to continue
providing heat after the moisture/temperature signals have been eliminated by a heating cycle.
