i-Vu® RTU Open
OPN-RTUM2

Product Integrated Controller

Integrated controller for rooftop units capable of stand-alone operation or integrated with Carrier’s or any Building Automation System using BACnet®, Modbus® or Lonworks® protocol.

The RTU Open controller continuously monitors and regulates constant volume rooftop operation with reliability and precision. This advanced controller features a sophisticated, factory-engineered control program that provides optimum performance and energy efficiency. It also features plug-and-play connectivity to the Carrier i-Vu Building Automation System.

For added flexibility, the RTU Open controller is capable of stand-alone operation, or, it can be integrated with any other Building Automation System utilizing the BACnet, Modbus®, LonWorks®, or N2 protocols.

System Benefits

  • Integrated Carrier airside linkage algorithm for plug and-play integration with the Carrier VVT® System
  • Fully plug-and-play with the Carrier i-Vu Building Automation System
  • Supports demand limiting for maximum energy savings
  • Compatible with i-Vu Tenant Billing for tracking tenants’ after-hours energy usage
  • Performance and utilization runtime data stored locally on the controller for system

Hardware Features

  • Can be factory-installed on Carrier WeatherExpert®, WeatherMaster®, and WeatherMaker® packaged rooftop units
  • Can be field-installed on constant volume rooftop units; wiring harnesses (sold separately), provide quick field installation
  • Integrates easily into any BAS using BACnet, Modbus, LonWorks1, or N2 protocols
  • On-board hardware clock, remote occupancy input, and support for Carrier communicating room sensors/thermistor sensors provide stand-alone operation
  • Easy startup and configuration with i-Vu User Interfaces

Application Features

  • Controls up to 2 stages of DX cooling (3 stages for 48/50 LC WeatherExpert®) to maintain space temperature setpoint
  • Controls up to 2 stages of gas heat or combination of mechanical and electric heat to maintain space temperature setpoint (controls up to 4 stages of heat in heat pump mode)
  • Integrated economizer2 and power exhaust control provide optimized free cooling in combination with mechanical cooling
  • 2 fan speed control options provide maximum energy savings and comfort
  • Built-in advanced control routines for zone level humidity control or zone level demand control ventilation (ASHRAE 62)
