Introduction

Image: The AC Infinity UIS to Molex Port Adapter Dongle (Model AC-ADQ3).
This instruction manual provides detailed information for the AC Infinity UIS to Molex Port Adapter Dongle, Model AC-ADQ3. This adapter is designed to facilitate compatibility between newer AC Infinity fans equipped with UIS connectors and previous generation AC Infinity controllers that utilize Molex ports. It enables intelligent programming features such as climate triggers, timers, and backup memory for compatible devices.
Setup and Connection
The AC-ADQ3 adapter provides a straightforward method for connecting your UIS-enabled AC Infinity fans to older Molex-port controllers. Follow these steps for proper connection:
- Identify Connectors: Locate the UIS connector on your newer AC Infinity fan (e.g., CLOUDRAY clip fans, CLOUDLINE LITE inline fans, next-gen CLOUDLINE fans) and the Molex port on your previous generation AC Infinity controller (e.g., CONTROLLER UNC529, CONTROLLER 67).
- Connect UIS End: Insert the male UIS end of the AC-ADQ3 adapter into the female UIS port of your fan. Ensure a firm and secure connection.
- Connect Molex End: Insert the female Molex end of the AC-ADQ3 adapter into the male Molex port of your controller. Verify that the connection is snug.
- Power On: Once both ends are securely connected, power on your AC Infinity controller. The adapter will now enable communication between your fan and controller.

Operating the Adapter
The AC-ADQ3 adapter functions as a passive conversion cable, enabling communication between devices. Once connected, the operation of your fan and controller will proceed as designed, with the added benefit of expanded compatibility.
- Smart Controls: The adapter allows UIS devices to access smart control features available on your Molex-port controller, including temperature and humidity triggers.
- Timers: Utilize the timer functions of your controller to automate fan operation.
- Backup Memory: Benefit from the controller's backup memory features, ensuring settings are retained during power interruptions.
Refer to your specific AC Infinity controller's instruction manual for detailed information on configuring and utilizing these smart control features.
Maintenance
The AC-ADQ3 adapter is designed for durability and requires minimal maintenance. To ensure optimal performance and longevity:
- Keep Connections Clean: Periodically inspect the UIS and Molex connectors for dust or debris. Use a dry, soft cloth or compressed air to clean if necessary.
- Ensure Secure Fit: Always ensure that both ends of the adapter are securely plugged into their respective ports to prevent intermittent connections.
- Avoid Stress: Do not bend or pull the cable excessively, especially near the connectors, as this can damage the internal wiring.
- Storage: When not in use, store the adapter in a clean, dry place away from extreme temperatures.

Troubleshooting
If you encounter issues while using the AC-ADQ3 adapter, consider the following troubleshooting steps:
- No Connection/Fan Not Responding:
- Ensure both the UIS and Molex connectors are fully and securely seated.
- Verify that the fan and controller are powered on.
- Check if the fan and controller are compatible with the adapter (refer to the compatibility section or your product manuals).
- Test the fan directly with a compatible UIS controller (if available) or the controller with a compatible Molex fan (if available) to isolate the issue.
- Intermittent Connection:
- Inspect connectors for any visible damage, bent pins, or debris.
- Ensure the cable is not under tension or sharply bent.
- Smart Features Not Working:
- Confirm that your controller model supports the desired smart features (e.g., temperature/humidity triggers, timers).
- Refer to your controller's manual for proper configuration of these features.
If problems persist after attempting these steps, please contact AC Infinity customer support for further assistance.
