Power Failure Alarm
After plugging in the equipment, move the “Reset Switch” located at the front of the unit to the down
position. When electrical power to the equipment is lost, an alarm will sound, and it will silence when
the power is restored. Note the alarm is battery-powered and has a limited time to alarm.
Min/Max Temperature Recording
Once connected to the power supply, your unit records the maximum high and minimum low
temperatures reached inside the cabinet. The display will show the last HI and LO temperatures
recorded until the refrigerator is reset.
To display the HI reading, press and release the HI/LO button. To display the LO reading, press and
release the HI/LO button again.
To Reset the Min/Max Temperature Recording
Hold the HI/LO button for 6 seconds. To confirm the operation, the display starts blinking and the
buzzer sounds. After 5 seconds, the normal display will be restored.
Changing the Temperature Display
This unit ships with the temperature being displayed in Fahrenheit. If you prefer the display in
Celsius, you will need to enter your password and adjust the parameters. Press and hold the “Set”
button until it flashes “Pas,” then enter the password (factory default is “15”) using the up and down
arrows. Once you enter the password, press “Set” about 25 times until “CF” displays, then press the
down arrow until the control displays “ºC”, then press “Set.” Wait 6 seconds and the setting will be
recorded, with your unit resuming normal operation.
Interior Light
Your unit includes an LED light that will automatically illuminate when the door is opened. If you
would like to keep the light on when the door is closed, push the switch to the “on” position.
Door Alarm
If the door of the refrigerator is left open for more than 3 minutes, an audible alarm will sound. The
alarm will be turned off automatically when the door is closed.
Remote Alarm
The electronic controller is equipped with dry contacts for alarm forwarding to an external remote
alarm system (terminal block on the back of the refrigerator).
