INTRODUCTION
ETN4-1999
is an all-in-one thermostat for DIN-rail mounting in an
approved cabinet. It covers the needs of a variety of applications
in which maximum comfort and minimum energy consumption are
required, e.g. electric floor heating, frost protection, ice and snow
melting, cooling, etc. The thermostat allows a required temperature
to be set within the range -19.5 to +70 °C. The large backlit display
provides a clear view of status, while the three navigation buttons
allow easy menu operation.
