The company offers a wide range of controllers: Smart II Plus, SMVU, RS, and NCRS™. Configured with the industry 0-10 vdc analog output, Smart II Plus controllers can work with the company's control system, such as the MS1800 Building Management System, or as a standalone unit. When the application calls for reduced input/output (I/O) configurations and nonplenum rated requirements, SMVU controllers are the alternative to Smart II Plus, says the company. Meanwhile, the RS controller provides I/O and control program flexibility that is important to many primary equipment applications. Finally, the NCRS controller connects the PC-based operator's MS1800 workstation to Smart II Plus, SMVU, and RS controllers.
