Operations
1. Under temperature measuring and controlling status:
1) Press the set key for 3 seconds:
When the keypad password is set as “0”, the set indicator light comes on and the screen
displays the “F01” menu. There is no password authentication, so directly enter the
menu mode to set parameter.
When the keypad password is not set as “0”, the set indicator light flashes and the
screen displays “00”. Press the up or down key to input the password. Press the set key
to confirm the password input. Then, the system enters the menu setting status if the
password is correct. If the password is incorrect, the set indicator light goes off and the
system goes back to the normal measuring and controlling status.
2) Parameter check:
Press the up key. The set indicator light flashes and the screen displays the set point
temperature.
Press the down key. The set indicator light flashes and the screen displays the
temperature of the evaporator sensor.
2. After entering the menu setting status, press the up or down key to choose the desired
menu item (from F01 to F09).
3. After choosing the desired menu item, press the set key to set parameter value. Press

Output Control
1. Compressor:
The compressor starts up when the delay time runs out, if the measured temperature is
higher than the “fixed temperature value + temperature return difference”.
The compressor stops running when the measured temperature is lower than the set point
temperature.
2. Defrosting:
Defrosting starts automatically according to the defrost cycle setting, or can be started
manually. If the evaporator sensor is activated and the evaporator sensor temperature is
higher than the defrost termination temperature, the manual start is not available.
