Daikin-McQuay KRP980B2E Adapter

The Daikin-McQuay KRP980B2E Adapter is a critical field-installed component designed to bridge the gap between specific ductless mini-split indoor units and professional-grade control interfaces. As a dedicated Wired Remote Interface Adapter, this PCB provides the necessary S21 protocol translation required to integrate standalone wall-mounted units with advanced control systems. For any contractor working on 19 Series, Aurora, or legacy FTK/FTX 18K and 24K systems, this adapter is the gateway to enabling wired remote controller functionality and WiFi cloud integration.

Engineered for high-reliability communication, the KRP980B2E allows for direct connection to BRC944B2 controllers or DKN Cloud adapters. It facilitates precise system management, including operation mode selection, setpoint adjustments (18°C to 32°C in cooling), and diagnostic monitoring. This low-voltage interface mounts internally within the indoor unit cabinet, ensuring a clean, professional finish for residential or light commercial applications. When your project requires Daikin-McQuay HVAC controls to interface with centralized management or simplified wired wall stations, this adapter ensures seamless data bus continuity without signal degradation.

• Mandatory S21 Conversion: Essential for units lacking a native S21 connector to enable BRC944B2 or DKN Cloud compatibility.
• Versatile Integration: Supports RA Interface Adapters for DIII-Net (KRP928BB2S) and Wireless LAN Connect Adapters for smart home setups.
• System Feedback: Empowers technicians with error code transparency and operating condition monitoring through the wired bus.
• Compact Form Factor: Designed for internal mounting to maintain the aesthetic integrity of the mini-split indoor unit.

Common Questions:

Does this adapter support group control of multiple indoor units?
No, the KRP980B2E is specifically designed to interface a single indoor unit with a single set of controls. It does not support group control or the daisy-chaining of multiple fan coils to one remote.

Is an additional cable required for installation?
While the adapter facilitates the connection, specific kits like the BRC944B2-A08 include the necessary wiring. However, if you are connecting both a wired controller and a DIII-Net adapter simultaneously, supplementary cables such as the BRCW901A08 may be required.

Which Daikin series are compatible with the KRP980B2E?
This adapter is primarily utilized for 18,000 and 24,000 BTU indoor units within the 19 Series and Aurora families (e.g., FTK18/24NMVJU, FTX18/24NMVJU). Always verify the unit's submittal data for S21 protocol requirements.
