OPERATING FUNCTIONS
After switching on the mains power supply, the display briefl y shows all display segments and
then switches to the currently measured temperature (e.g. 21.5 °C).
Displaying limit values
• Press key "S" briefl y: The upper limit value is displayed
• Press key "F" briefl y: The lower limit value is displayed
After about 2 seconds, the display switches back to the current temperature again.
Opening the setup menu
A three-digit password has to be entered to prevent alteration of the settings by unauthorised
persons. The password "111" is pre-set by the manufacturer upon delivery.
To open the setup menu, proceed as follows:
• Keep the "SET" button pressed for 3 seconds; 3 dashes appear on the display, the left one
of which fl ashes.
• Set the fi rst digit of the password with the buttons "S" and "F".
• Confi rm with the " " button; the second dash starts fl ashing.
• Set the second digit of the password with the buttons "S" and "F".
• Confi rm with the " " button; the third dash starts fl ashing.
• Set the third digit of the password with the buttons "S" and "F".
• Confi rm your input with the button "
• If the password ("111" in the factory setting) was entered correctly, the display shows "F01"
and you can select the desired function with the buttons "S" and "F".
If an incorrect password was entered, three dashes appear again and the password has to
be re-entered.
If the password is entered three times incorrectly, or if for about 30 seconds no button is
pressed, the display switches back to the actual temperature.
Selecting functions in the setup menu
• Select the functions "F01".... "F08" and "P01"... "P03" with the buttons "S" and "F".
The functions F05, F06, F07 and F08 are not available for "ETC-100+".
Code Function
F01 Upper temperature limit
F02 Lower temperature limit
F03 Temperature calibration
F04 Switch-on delay
F05 Defrost cycle
F06 Defrosting duration
F07 Temperature alarm limit
F08 0 = cooling mode, 1 = heating mode
P01 First digit of password
P02 Second digit of password
P03 Third digit of password
Displaying and changing the setting value
• With the button " " the current setting value of the respective function is shown.
• When the setting value appears on the display, it can be adjusted with the buttons "S" and
"F". For a quick adjustment, press and hold the corresponding button for a longer period of
time.
• Press the "SET" button briefl y; the setting value fl ashes for 2 seconds and the display
returns to the function selection.
The new value is not saved yet, but only added to the temporary memory.
Saving all setting values
Keep the "SET" button pressed for 3 seconds; all setting values are thus added and saved.
The setup menu closes automatically and the current temperature appears again in the
display.
Not saving setting values
If you do not press any button within 30 seconds, the thermostat returns to the current tem-
perature. Possible adjustments are not saved; the previous setting values remain activated.
For this reason, do not allow too much time in the changing of setting values; otherwise
the setting mode will close without saving!

COOLING MODE
The cooling process is started if the measured temperature is above the upper temperature
limit (adjustable with function "F01").
The cooling process is stopped if the measured temperature drops below the lower tempera-
ture limit (adjustable with function "F02").
HEATING MODE ("ETC-200+")
This function is available only for "ETC-200".
In the heating mode, the heating process is started if the measured temperature drops below
the lower temperature limit (adjustable with the function "F02").
The heating process is stopped if the measured temperature is above the upper temperature
limit (adjustable with function "F01").
SWITCH-ON DELAY
This function is active only during the cooling mode.
When the power supply is switched on, the thermostat measures the current temperature.
If this temperature is above the upper temperature limit (function "F01"), the cooling process
is not yet started; instead, the thermostat waits for the time of the switch-on delay (function
"F04"; the value can be set to 0-30 minutes; the factory setting is 3 minutes).
This protects the compressor from starting too often in case of an error (e.g. disturbances in
the power supply).
DEFROST FUNCTION ("ETC-200+")
This function is available only for "ETC-200+"; furthermore, the cooling mode must be
activated (function "F08" must be set to "0").
The automatic defrosting process is started according to the settings of the defrost cycle
(function "F05"); the duration is determined in function "F06".
The defrost function is deactivated if either defrost cycle (function "F05") or defrosting dura-
tion (function "F06") are set to "0".
Start a manual defrost process by pressing and holding the button "
until the defrost LED " " fl ashes. Stop the manual defrosting procedure in the same manner
(press the button " " approx. 3 seconds until the defrost LED goes out).
ALARM FUNCTIONS
• Input error
If "Er" fl ashes on the display, an error was determined during saving. This can occur during
the initial startup or during the saving of setting values. Press any key.
• Sensor alarm
If "E01" fl ashes on the display and an alarm sounds simultaneously, the thermostat de-
tected an error in the sensor (e.g. faulty connection or no cable connected, cable too long)
• Temperature range alarm
If the measured temperature exceeds the permissible temperature range (-40....+120 °C),
"E02" fl ashes in the display and an alarm sounds.
• Alarm when exceeding the temperature alarm limit ("ETC-200+")
A value between 0....20 °C can be set as temperature alarm limit in function "F07"
("ETC-200+" only).
The alarm is triggered (display fl ashes and alarm sounds) if:
measured temperature > (upper temperature limit) + (temperature alarm limit)
Example: 123 °C > (80 °C) + (20 °C)
or
measured temperature < (lower temperature limit) - (temperature alarm limit)
Example: -40 °C < (-10 °C) - (20 °C)
• Deactivating the alarm sound
Press any key to turn the alarm sound off.
TEMPERATURE CALIBRATION
The temperature can be calibrated with the function "F03" in the setup menu by setting a
correction value (-5 °C.....+5 °C).
