Programming Mode

The Programming Mode of the Dixell Prime Controller allows you to customize various parameters to tailor the controller’s behavior to your specific refrigeration needs. To access this mode, press and hold the SET key for 3 seconds. This action will initiate the Programming Mode, indicated by the C or F LED starting to blink. You can then navigate through the available parameters using the UP and DOWN keys. To select a parameter, simply press the SET key. The selected parameter will be displayed, along with its current value. To change the value of a parameter, use the UP and DOWN keys to adjust it to your desired setting. Once satisfied, press the SET key to confirm the new value.

The Programming Mode offers a wide range of parameters to modify, including⁚

• Set point⁚ This parameter defines the desired temperature for the refrigeration system.
• Differential⁚ This parameter sets the temperature difference between the set point and the actual temperature at which the compressor will turn on or off.
• Minimum set point⁚ This parameter defines the lowest temperature that the system can reach.
• Defrost cycle settings⁚ This parameter controls the duration and frequency of defrost cycles.
• Fan control⁚ This parameter allows you to adjust the fan speed or enable/disable fan operation.
• Alarm settings⁚ This parameter configures the alarm thresholds for various system conditions.

Refer to the specific documentation for your Dixell Prime controller model for a complete list of programmable parameters and their descriptions.

Hot Key Programming

Hot Key Programming is a convenient feature of Dixell Prime controllers that allows you to quickly program multiple controllers with identical settings, eliminating the need to manually program each one individually. This streamlined approach saves time and ensures consistency across your refrigeration system. To utilize Hot Key Programming, you’ll need a dedicated Hot Key programming keyboard.

The process typically involves these steps⁚

1. Program one controller using the front keypad, setting all the desired parameters.
2. While the controller is ON, insert the Hot Key and press the corresponding key. This action initiates the Hot Key programming mode, indicated by the uP message followed by a flashing Ed on the display.
3. Press the SET key. The flashing Ed will stop, confirming that the controller is ready to receive the programming data.
4. Turn OFF the instrument and remove the Hot Key.
5. Connect the Hot Key programming keyboard to the second controller.

7. Repeat the process for each additional controller you wish to program.

Hot Key Programming simplifies the process of configuring multiple Dixell Prime controllers, ensuring that all controllers in your system operate with the same settings, contributing to a more efficient and reliable refrigeration system.

Manual Defrost

Manual Defrost is a feature that allows you to initiate a defrost cycle manually, providing greater control over the defrost process. This feature proves invaluable in situations where you need to expedite defrosting or address specific defrosting needs that might not be adequately addressed by the controller’s automatic defrost cycle.

To initiate a Manual Defrost cycle, simply press and hold the DEF key on the controller for more than two seconds. Once activated, the controller will begin the defrost process. The duration of the defrost cycle is determined by the parameters you’ve configured in the controller’s settings.

Manual Defrost provides you with the flexibility to address defrosting needs that may arise due to environmental factors, operational changes, or specific requirements within your refrigeration system. By manually triggering defrost cycles, you can optimize defrosting efficiency and ensure that your refrigeration system operates at peak performance.

It’s important to note that Manual Defrost should be used judiciously. Excessive manual defrost cycles can lead to increased energy consumption and potential wear on the defrost components. Refer to the controller’s manual for specific guidelines on using Manual Defrost.

Changing Parameter Values

Parameter values within the Dixell Prime controller govern various aspects of its operation, including temperature setpoints, defrost cycles, and alarm thresholds. Changing these values allows you to tailor the controller’s behavior to meet the specific needs of your refrigeration system;

To change parameter values, you first need to enter the Programming Mode. This is accomplished by pressing and holding the SET keys for 3 seconds. The C or F LED will start blinking, indicating you’ve successfully entered Programming Mode.

Once in Programming Mode, use the navigation keys to select the parameter you wish to modify. The controller will display the current value of the selected parameter. Use the up and down arrow keys to adjust the value as needed.

After modifying the parameter value, press the SET key to save the change. The controller will then move to the next parameter. You can continue changing parameter values until you’ve completed all necessary adjustments.

To exit Programming Mode, press the SET key and then wait for 15 seconds without pressing any keys. The controller will return to its normal operating mode.
