The factory default resumption
Press and hold
and
at the same time for more than 10 seconds. The indicators will flash and all
parameters will be resumed as same as factory defaults. After about 10 seconds, it will return to the normal
operation.
Lock parameters
In normal operating state, press and hold
for more than 10 seconds to lock the parameters if “OFF” is
displayed or to unlock if “ON” is displayed. Parameter can be displayed only and not be modified if locked, but
the adjustment of the set temperature is active (the factory default is “ON”).
Temperature control
After turning on for the delay time, the compressor starts operating and fan starts operating after the delay
time when storage temperature is higher than set temperature plus hysteresis, will be off when storage
temperature is lower than set temperature.
When the compressor stops and the stop time is longer than the delay time (Parameter E4), the compressor
will restart.

After operating for a defrosting period (parameter F2), it enters turning-off state automatically. The
compressor stops and evaporation fan operates; It enters automatic temperature control state after certain
time (parameter F1).
When parameter F4=1, the storage temperature is locked during defrosting, the temperature in the
defrosting start is displayed. After defrosting, the storage temperature display will be resumed normal after
displaying delay parameter F6.
When the duration of defrosting is set to “00”, the function of automatic defrosting will be cancelled.
Press
and
simultaneously and hold for about 6 seconds to enter the parameter setup mode
while F1 will flash. Repeatedly press
again to select the desired parameter. Press
/
, the
value of parameter will be displayed and can be modified and stored.
If no button is pressed within 10 seconds, it will return to normal operation mode.
Abnormal work mode
When the storage temperature sensor is short circuit or overheated (
≥
99°C), “HHH” will be displayed; when
the storage temperature sensor is open circuit or temperature is too low (
＜
50°C), “LLL” will be displayed. At that
time the compressor will enter timing operating mode automatically by the cycle of 45 minutes on and 15
minutes off.
