Description of LEDs and buttons

LED	Description
	ON/OFF - If the LED is on, the device is Off
	Compressor - If the LED is on, the compressor is on - If the LED is flashing, compressor protection is in progress
	Defrost - If the LED is on, defrosting is in progress - If the LED is flashing, condensation is in progress
	Celcius - if the LED is lit, the temperature is displayed in Celsius.
	Fahrenheit - if the LED is lit, the temperature is displayed in Fahrenheit.
	Power Saving - If the LED is lit, the power saving function is enabled.
	Warning - If the LED is flashing, the alarm and fault functions are in progress.
Button	Description
	- In "Operating Mode", shows the value - in "Programming Mode", displays the value of the selected parameter and confirms the changed value.
	- in "Operation Mode", manual defrosting, if conditions allow. - in "Programming Mode", switching between parameters and increasing the value of the selected parameter.
	- in "Operation Mode", displays the evaporator temperature (P4=1). - in "Programming Mode", Programming", switching between parameters and decreasing the value of the selected parameter
	- in "Operating Mode", turning the device off/on - in "Programming Mode", returning to Operating Mode

1. Viewing and changing the setpoint

Translation: Measured Value -> Measured Value

If the button is pressed for 2 seconds in "Operation Mode," the setpoint value is displayed for 3 seconds. During this time, you can change the setpoint value using the buttons.

2. Reading the value measured by the defrost probe

Translation: Measured Value -> Measured Value

In "Operation Mode", if the second input type is set to Analog Input (P4=1), pressing the button for 5 seconds will display the value measured by the defrost probe.

3. Locking and unlocking buttons

Translation: Measured Value -> Measured Value

Keys are locked. -> The buttons are locked.

If the buttons are pressed simultaneously for 3 seconds or no buttons are pressed for 1 minute in "Operation Mode", the message Lc will be displayed and the buttons will be locked. If the buttons are locked and any button is pressed for 2 seconds in "Operation Mode", the message uL will be displayed and the buttons will be unlocked.

4. Manual Defrosting

If the button is pressed for 4 seconds in "Operation Mode", the defrosting process is manually enabled or disabled.

1) If parameter d3=0, manual defrosting is also disabled.

2) If the second input type is set to Analog Input (P4=1), defrosting will not start if the measured value of the defrost probe is greater than the value of parameter d2.

5. Manually turning the device on/off

If the button is pressed for 3 seconds in "Operating Mode" (without button lock), the display turns off, temperature measurement and control are not performed, and the output becomes passive. If the button is pressed again for 3 seconds, the display turns on, and the device continues to measure and control the temperature.

6. Factory Settings

If the PS parameter is set to 1: The PA Safety Parameter is set to -44 and the button is pressed, the dF message will appear on the display. If the button is pressed again while the dF message is displayed, the "---" message will flash for 4 seconds, then the device will revert to the factory settings and return to "Operation Mode".

If the PS parameter is set to 0: if the button is pressed first, and then the button is pressed and held together for 5 seconds in "Operation Mode", the dF message will appear on the display, the device will return to the factory settings and return to "Operation Mode". will revert to factory settings and return to "Operation Mode."

7. Displayed update dates

Translation: Measured Value -> Measured Value

YY/MM/DD -> YY/MM/DD

If the buttons are pressed simultaneously in "Running Mode", the update date will be displayed in the YY/MM/DD format.

8. Changing Parameter Values

Translation: RUNNING MODE -> OPERATION MODE

Temperature Value -> Temperature Value

Press the SET key for 4 seconds to enter settings mode -> Press the SET key for 4 seconds to enter settings mode

Settings -> Settings

Password Activation Msg. -> Password Activation Message

If the value -23 is entered, the parameter settings are accessible -> If the value -23 is entered, the parameter settings will be accessible

Parameter settings -> Parameter Settings

If the button is pressed for 4 seconds in "Operating Mode", the password message (PA) is displayed on the screen. By pressing the button, set the password to "-23" using the buttons, then click again to enter the Parameter Settings. Thanks to the buttons, we can select a specific parameter, then by clicking , the parameter value will be displayed. The value of the appropriate parameter can be changed using the buttons. If no operation is performed while the parameter value is displayed or the button is pressed again, the parameter name will be returned. If the button is pressed while the parameter name is displayed, this time the exit will occur without waiting.
