The rooftop unit multi-protocol (RTU-MP) controller is a factory-installed direct digital control. The control enables rooftops to be integrated with a building automation system via BACnet, Modbus®, Johnson Controls N2. or LonWorks® protocols, providing unit diagnostics and status broadcast over network communications. The controller monitors and integrates all cooling, heating and economizer operations. The multiprotocol controller is factory-installed and certified, providing multiprotocol availability from a single controller. Protocol selections can also be easily completed in the field using the controller's onboard dipswitch. It provides unit diagnostics and status network communications at the unit or remotely for ease of service.
