1.Dimensions and Panel mounting
Installation Precautions
-The thickness of the mounting panel should be in the range from 0.8 to 2.0mm;
-Please ensure that the working environment of the controller meets the requirements in the
technical parameters before installation;
-Do not install the instrument in damp or dirty places; in fact, it is suitable for use in places with
ordinary or normal levels of pollution. Keep the area around the instrument cooling slots adequately
ventilated.

3.3 Normal operations
How to change the shutdown temperature and other parameters
Note(1):If there is no operation for more than 30 seconds, give up parameter modification
and exit parameter modification;
Note(2):If you forget your password, please call the manufacturer.
How to view the control probe temperature
When C9=1 and the control sensor is normal, press the SET button to display the
temperature of the control sensor.

MEC-18x User Manual |Code M01C230116| Jan. 16th,2023 Ver2.13 2/4
How to check the temperature of the evaporation probe
Press the
key, the evaporation probe temperature will be displayed, and the
normal display will be restored after 1 second.
Note: Only when the evaporation probe is enabled (d1=1) and the evaporation probe is
normal (no E2 fault) can you view the evaporation probe temperature, otherwise there will
be no response when you press the key.
How to manually start or stop the defrost
Press and hold the key for 3 seconds to manually start or stop the defrost.
How to set the recorder clock
In the parameter setting interface,Pressing SET button for 3s to display "Yea",
and to switch between year, month, day, hour, minute and second.
And press the SET key again to switch between parameter items and parameter
values; After pressing the SET key, if the clock has changed, modify the recorder clock
and exit the setting mode; Otherwise, the clock will not be changed.
If there is no key operation within 30 seconds, it will automatically exit the setting
interface without setting the clock.
Note：Every time you reset the recording clock and parameters, the previously recorded data
will be cleared. Please pay attention to data storage before operation.
Quickly clear and re record data
After Pressing + button for 5s to display the "cFg", and the current data of
the recorder will be cleared. At the same time, the recorder will be reconfigured
according to the current parameters, and new data recording will be started again.
Tips for USB flash disk exporting data
Insert the USB stick into the recorder and start exporting data.
During the export process, the controller displays the current progress (0~100%)
every 3 seconds, the recorder gives a short sound every 2.5 seconds, and the blue
indicator flashes.
After the data export is completed, the controller displays "OK", the recorder buzzer
sounds for a long time, and the blue indicator is always on. At this time, you can
remove the USB flash disk.
Note(1): During data export, please ensure that the main power supply is stable, and do not
pull out the U disk in advance;
Note(2): It is prohibited to export data from the USB flash disk when the main power is off.
Power failure prompt
Display: When the mains power is cut off, the controller will display and prompt once
every 6 seconds. The display temperature accuracy is adjusted to 1.
Alarm: When A13=0, the controller prohibits noise reduction;
When A13=1, press any key to silence.
