Note:

Always turn on the battery switch before starting the freezer. The freezer will enter normal working state and charge the battery upon connecting to an AC power supply meeting its requirements. In case of AC power failure, the battery will energize the display screen for normal display. When the voltage of battery reduces to less than a specified value due to discharge, it will stop energizing the display screen and thus the display screen will not display any longer. When the battery is able to supply electricity normally, to completely cut off the freezer’s power supply, just pull out its AC power cord and turn off its battery switch. Then the display screen will not display any longer.

Time setting for automatic alarm recovery

At the time of alarm, press the “Cancel buzz” key on the display panel, buzz alarm will be cancelled (remote alarm will not be cancelled).

If alarm conditions remain, the buzz alarm will automatically recover after a pause of 30min.

Remote alarm terminals

The remote alarm terminals are located in the compressor compartment at the back of freezer. Alarm signals are sent by these terminals with carrying capacity of DC 30V, 2A. Contact output:

In normal conditions, both ends of connecting wire of remote alarm terminals are open circuit. In alarm conditions, both ends of connecting wire of remote alarm terminals are closed circuit.

To use the remote alarm function, connect the circuit as shown in the figure below. Note: The remote alarm function is limited to three alarm modes - high temperature alarm, low temperature alarm and power-down alarm.

Note: If several alarms sound simultaneously, each fault code displays 3s.
