Comprehensive Guide to Configuring Your Dixell Controller for Atosa Refrigerators
Welcome to our detailed guide on configuring the Dixell Controller for Atosa units, specifically for refrigerators. This guide will walk you through all the necessary settings to ensure your Atosa refrigerator operates efficiently. Whether you're handling a new installation, recovering from a power outage, or simply performing routine maintenance, this guide is your go-to resource.
Understanding the Startup Sequence
When you first power on your refrigerator, you might notice the display showing T1 and T2U. It's important to note that this is not an error code. Instead, it's the startup sequence. Allow it to complete, and eventually, the display will show the current temperature, indicating that the unit is functioning properly.
Accessing the Second Level of Settings
To access the second level of settings, you'll need to act quickly. If you take more than 3 to 5 seconds to press any button, the controller will time out and return to the regular temperature display. This process is crucial if you've experienced a power outage or moved your unit to a different outlet, as these events can disrupt the settings.
If you prefer not to handle this yourself, you can request a service call. However, please note that such visits are not covered under warranty, and you'll incur out-of-pocket expenses. It's often more convenient and cost-effective to adjust the settings yourself.
Steps to Enter the Settings
To enter the settings on your Dixell Controller, follow these steps:
1. Hold down the Set button and the Down Arrow simultaneously until the display reads HY.
2. Release the buttons, then press and hold them again for about 10 seconds. The display will show L2, and then switch to H.Y.
3. Use the Set button to navigate through the settings.
Essential Settings for Optimal Performance
Let's go through the critical settings you need to configure for your refrigerator:

- P2: Set to END as no secondary probe is needed.
- OE: Set to 0, since there is no secondary probe.
- o d: Set to 2. Press the Set button to lock it in.
Defrost and Cycle Settings

Final Steps and Troubleshooting
Once you've configured these settings, you'll notice D1 and D2 appear on the display. These are readout-only settings that show the current probe readings. Since this is a refrigerator, no secondary probe is required.
To exit the settings menu, you can either wait for about 15 seconds for the system to reset automatically or hold down the Set button and press the Up Arrow.
If your refrigerator's temperature is higher than desired, usually set in the 30s but reading in the 40s, revisit these settings. Sometimes, inadvertent adjustments can throw off the cycle, so it's beneficial to check these parameters regularly.
By following this guide, you can ensure your Atosa refrigerator operates smoothly and efficiently, avoiding unnecessary service calls and prolonging the life of your appliance.
