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.

Thermostat operation
The ON/OFF button is used to turn the thermostat off "0" or on "I".
When the ON/OFF switch is in position "0", the relay is deactivated.
All settings are saved.
The thermostat is easily operated using the navigation buttons.
Basic functions like temperature and thermostat settings are sim-
ple to perform. Whenever a button is pressed, the backlighting will
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.
Settings
To set parameter values, press and hold the centremost button for
three seconds. SCA  Hi  40 will appear on the display. Firstly,
SCA will be displayed for 1 second, followed by Hi, and finally 40.
The required value can now be set using the navigation buttons. To
access the next parameter, press the programming button again.
If no button is pressed for 30 seconds, the program returns to the
initial display.
