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.

come on and stay lit for 30 seconds after a button is last pressed. 

Temperature setting

The thermostat has a temperature setting range of -19.5 to +70 °C. 

The menu allows limits to be defined for the range within tempera-

ture may be set (factory setting = 0-40 °C). The required temperature 

is set using the left- or right-hand button. The temperature setting 

flashes on the display. Five seconds after the setting has been made, 

the required temperature will be shown on the display continuously.
