If you want to reset the temperature, for example, 5℃ is set originally and you want to change the
temperature to 5.5℃, please operate according to the following steps:

Key Operation
Display
Press both “Sensor” and
“Cal Cancel” for 5s at
the same time.
Click “Cal Cancel”
(0.1℃ higher/time) or “Sensor”
(0.1℃ lower /time)
After the demanded temperature 5.5℃
is set, stop the operation.
The temperature in the refrigerator displays.
The original temperature set value 5℃
appears and flickers.(Please follow the
following steps in 5s since the value
flickers. Otherwise, the display panel will
return to the temperature in the refrigerator)
The temperature value 5.5℃ stops
flickering after being displayed and
flickering for 5s and then is saved in the
system. After successful setting, the
display panel will display the temperature
in the refrigerator again.
The original temperature set value 5℃
changes accordingly, until the temperature
displayed on the display panel is 5.5℃.
Defrost Cycle
The refrigerator has two automatic defrost cycles.
1) Cycle defrost
To maintain a constant temperature inside the refrigerator, the refrigeration system cycles on and off
according to the temperature demand. When the refrigeration compressor cycles off, a small electric
heater is energized to thaw the frost off the evaporator surface. The function does not have an
obvious impact to the chamber temperature.
2) Forced defrost cycle（HYC-260/360/290/390/390F only have this funtion)
When the environmental humidity is too high or the products loaded into the refrigerator emit much
moisure, cycle defrost will not be sufficient to remove all frost and ice accumulated on the evaporator
surface. The equipment will start the forced defrost cycle. Once the frost is thawed, the refrigerator
will resume normal operation.

Temperature Recorder (optional)
Chamber temperature recorder with 6 inch standard panel is optional for HYC-610 to record
chamber temperature change.
Installation and operation
To operate and use the recorder correctly, please follow the steps below:
1. Open the recorder door to see the recorder;
2. Switch on the 9V DC battery on top right corner of the recorder, the battery is standby power;
3. Check the recording paper. If it is necessary to replace the paper, please follow the operation
steps in P24;
4. Take down plastic cap of recording pen and close the recorder door.
Power supply
When the storage box operates, the recorder normally use AC supply. If the AC power supply fails,
LED indicator light on the recorder will blink and give alarm to indicate abnormal power supply. The
recorder continues to record chamber temperature through standby battery supply. Each standby
battery supply can sustain power for nearly 30h (Note: The battery shall be replaced timely when the
battery is low to avoid corrosion of battery button caused by delayed replacement. To save battery,
please disconnect battery button when the storage box is not used. During normal use, please install
standby battery to ensure normal recording in case of power failure). LED indicator light of the
recorder blinks continuously until main power supply (AC) is switched on and its stand-by power
battery is replaced. When the standby battery is low, LED indicator light of the recorder blinks to
indicate that the battery shall be replaced.
The recorder will not work until the chamber temperature reaches record range of
the recorder.
