This section explains how to operate your unit. For more detailed instructions on changing the parameters of the control panel, see page 13.

Once plugged in, the display will show the product temperature inside the freezer and the compressor will start to run (an indicator light on the control panel will turn on at the same time).

NOTE: This unit includes four sensors:

Compartment	Display Sensor	Control Sensor
Refrigerator	Product Sensor	Air Sensor
Freezer	Product Sensor	Air Sensor

For maximum performance, the refrigerator and freezer controls use a separate air sensor to control cooling. This sensor allows it to respond quickly to product loading and door opening. You may need to set the controller to a lower temperature, as the air temperature must be colder than the product to effectively bring it down.

The display shows the product temperature, recorded by a sensor in a glycol-filled vial inside the refrigerator and freezer compartments. As the refrigerator and freezer cool to their set point, the temperature on the display will decrease slowly, since the vial cools more slowly than the air.

IMPORTANT: If power is lost, wait for at least 5 minutes before plugging the unit back in to avoid damaging the compressor.

Adjusting the Operating Temperature

To change the set point:

1. Press the SET button. The current set point temperature will appear on the display.
2. Within 10 seconds, press the up or down arrows until the desired temperature is shown.
3. Press the SET button again to confirm and save the new set point.

All models are preset to 4^ (39.2^) and -25^ (-13^) . Adjust the temperature up or down to achieve your desired product temperature the displayed temperature.

High/Low Temperature Alarm

Your refrigerator and freezer have built-in alarms for temperature issues:

• LO: If the temperature drops below the low alarm set point, an alarm will sound and the display will flash [LO] with the current temperature.
• HI: If the air temperature goes above the high alarm set point, an alarm will sound and the display will flash [HI].
  H2: If the product temperature goes above the high product alarm set point, an alarm will sound and the display will flash [H2].

There could be several reasons for these alarms, which should be investigated immediately.

Continue monitoring the freezer to ensure it returns to the correct temperature. Alarm thresholds can be adjusted in the parameter setup menu to suit your specific requirements.

Power Failure Alarm

After plugging in the unit, move the Reset Switch (located at the front) to the down position. If power is lost, a battery-powered alarm will sound and stop once power is restored.

Note: The alarm will only sound for a limited time, as it runs on battery power.

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 it is reset.
• To view the HI temperature, press and release the HI/LO button once.
  To view the LO temperature, press and release the HI/LO button again.

Resetting the Min/Max Temperature Recording

• Press and hold the HI/LO button for 6 seconds.

FUNCTION DETAILS

Temperature Control:

After the unit is powered on and the delay time (parameter E40) has passed, the compressor will:

• Turn ON when the cabinet temperature is higher than set temperature + hysteresis.
• Turn OFF when the cabinet temperature is lower than the set point temperature.

To prevent damage, the compressor will not restart until the delay time (Parameter E41) has elapsed after shutting off.

Defrost Control:

The unit automatically enters defrost mode after operating for a set interval (parameter F2), then the compressor will stop. Defrost continues for the duration set by (parameter F1). After a defrost period ends, there will be 2 minutes of dripping time before the unit resumes refrigeration.

F2 = 00: The automatic defrost will be disabled and the compressor will not shut off or defrost.
- F4 = 0: The temperature will display during defrost.
- F4 = 1: The cabinet temperature is locked during defrost and the last value before defrosting will display. When defrost ends, the display returns to normal after 20 minutes (or when the cabinet temperature is lower than the set temperature). The defrost LED flashes during the delay.
- F4 = 2: The set temperature will be displayed during defrost. When the defrost ends, the display will return to normal after the 20 minutes delay (or cabinet temperature lower than the set temperature). The defrost LED flashes during delay.
- F4 = 3: The display shows [dEF] during defrost. When the defrost ends, the display will return to normal after the 20 minutes delay (or cabinet temperature lower than the set temperature). The defrost LED flashes during delay.

Alarm Control:

After powering on the unit for the first time, it must pass the C5 delay time before temperature alarms (C1, C2, C3) become active.

Air Temperature Alarms:

If the cabinet temperature rises above the high alarm (C1) or falls below the low alarm (C2) for longer than the alarm delay (C6), an alarm will activate:

• Hig h Temperature Alarm - Display alternates [H1] and the cabinet air temperature. The compressor turns on.

When cabinet temperature is lower than (high temperature alarm value C1 -alarm hysteresis C4), the high temperature alarm ends.

• Low Temperature Alarm - Display alternates [LO] and the cabinet air temperature. The compressor turns off.

When cabinet temperature is higher than the (low temperature alarm value C2 + alarm hysteresis C4), the low temperature alarm ends.

Product Sensor High Temp Alarm:

When the product sensor temperature is greater than or equal to the product temperature high temperature alarm value C3 and duration more than alarm delay time C6, unit enters alarm status, and starts the alarm, alternate display [H2] and cabinet temperature. When the product sensor temperature is less than or equal to the (high temperature alarm value C3 - alarm hysteresis C4), it will end the high temperature alarm.

Power Failure Alarm:

If power is lost, the display will flash [EEL] and an alarm will sound.

Door Alarm (do1 setting):

• do1 = 00: No alarm when door is open
• do1 = 0: After the set delay, the display shows [dr alarm]; press any button to cancel

Alarm Relay and Buzzer Behavior:

• C7 = 0 , then the units relay does not alarm when power is off.
• C8 = 0 , then after alarm is canceled, the alarm relay does not close.
• C9 = 0 , then after the alarm cancel button is pushed, the buzzer does not restart.

If setting other numbers, then after reaching delay time, buzzer sounds one more time. (Under the condition of alarm not terminating)

Abnormal Work Mode:

Air Sensor Faults

• When the air sensor is short-circuited or high temperature over limit (>66^ / 151^) the display will show [1H]
• When the air sensor is open-circuited or low temperature over limit (< -40^ / ^) the display will show [1L]
• Compressor will enter the force running mode, according to C10/C11 setparameters running in sequence.

Product Sensor Faults

• Short-circuit or temp >66^ (151°F): Display alternates [2H] and air temperature
• Open-circuit or temp < -40^ (-40°F): Display alternates [2L] and air temperature

Installation Notes:

1. Keep sensor leads separate from high-voltage power wires to prevent electrical noise.
2. Use a separate power supply for the load and the controller.
3. When installing the sensor, position the sensor head upward and the wire downward.
4. Do not install the temperature controller in areas exposed to water or dripping moisture.

DEFROSTING

Refrigerator Compartment - Cycle Defrost

The refrigerator compartment features an adjustable cycle defrost operation. The defrost cycle can be initiated automatically via the controller or manually by the user. By default, the compressor shuts off for a maximum of 20 minutes during the defrost mode. However, the default defrost interval is set to zero (0), so the defrost cycle does not run automatically under normal conditions unless it's manually activated.

Manual Refrigerator Defrost

1. Press HI/LO button
2. Press and hold the SET button for 6 seconds to enter or exit defrost mode.

Freezer Compartment - Manual Defrost

The freezer compartment requires manual defrosting. For optimal performance, defrost the freezer when approximately 14 inch of ice has accumulated inside the cabinet. Before defrosting, remove all contents from the freezer and set the controller to the warmest temperature (10°C). Leave the door open until all ice and frost have fully melted.

To accelerate defrosting, you may place a container of warm water (approximately 125^ ) inside the cabinet. Use clean towels or a sponge to soak up any water, and ensure the interior is completely dry before resetting the thermostat to its normal temperature.

IMPORTANT: It is not advisable to heat the interior of the freezer directly with hot water or a hair dryer while defrosting since this can deform the cabinet interior.

NEVER USE A METAL OBJECT TO REMOVE ICE FROM THE REAR WALL. IF NEEDED, USE A PLASTIC ICE-SCRAPER.

CLEANING AND MAINTENANCE

Before cleaning, it is essential that you unplug the unit from the power line and transfer the contents where they can be stored and monitored at the correct temperatures.

Use warm water and a neutral detergent to clean the interior compartment.
- Do not allow the control panel, power cord, or plug to get wet.
- Never use corrosive cleaners, wire brushes, abrasive pads, or sharp tools to clean the unit.
Thoroughly dry all surfaces before restarting the unit.
- The condenser is located at the back of the cabinet. To ensure trouble-free operation, the condenser should be cleaned every three months where appropriate using a vacuum hose.
- In exceptionally dusty locations, the condenser should be cleaned more often.

When moving the unit, keep it upright. The angle between the unit and the horizontal surface should be at least 50^ . Tilting below this angle may damage the compressor and affect normal operation.
