Information About OPN-RTUM2
The OPN-RTUM2 controller is part of Carrier’s RTU Open series, designed to manage rooftop unit operation either independently or as part of a connected Building Automation System. Built with a robust onboard control algorithm, it regulates heating, cooling, ventilation, and fan functions to maintain consistent environmental performance. With support for open communication protocols—BACnet, Modbus, LonWorks, and EIA-485—the controller integrates easily with Carrier i-Vu systems as well as third-party BAS networks. Its I/O configuration includes six analog inputs, five binary inputs, two analog outputs, and eight binary outputs, providing flexibility for various RTU configurations. Powered by 24 VAC at 50/60 Hz, the OPN-RTUM2 is engineered for reliable operation in commercial HVAC applications where interoperability and precise control are essential.
Key Features
- Multi-protocol support: BACnet, Modbus, LonWorks, and EIA-485 communication for universal BAS integration.
- Stand-alone capability: Operates independently without requiring a central automation system.
- Optimized RTU control: Factory-engineered logic for constant-volume rooftop unit operation.
- i-Vu plug-and-play compatibility: Enables seamless setup within Carrier building automation platforms.
- Expanded I/O options: Includes 6 analog inputs, 5 binary inputs, 2 analog outputs, and 8 binary outputs.
- 24 VAC power input: Compatible with standard HVAC control transformers.
- Flexible deployment: Supports OEM installation, retrofit upgrades, and multi-system BAS integration.
- Reliable operation: Designed for continuous environmental monitoring and energy-efficient performance.
The OPN-RTUM2 provides the control flexibility, communication capability, and reliability required for modern rooftop HVAC automation.
