The NEWS staff was very busy at the AHR Expo in Dallas, seeking information on new products. Here is a comprehensive list of the commercial controls we found on the show floor.
Designed for high-voltage fan coil and baseboard applications, the SimpleComfort® SC700 series of fan coil thermostats includes four UL-listed, nonprogrammable models. They support 24 or 115-277 vac, three-speed fan, four-pipe heat/cool applications with precise comfort controls accurate to ±1°F.
It’s no secret sensors play a critical role in building automation operation and efficiency. Their impact and effectiveness will depend on how the sensors correlate with other devices and components across the greater HVAC system. This requires some emphasis on effective design attributes and integration strategies.
Variable-frequency drive (VFD) control panels, the Endura™ line, has been introduced. The Endura PB (Pressure Booster) Control Panel is designed for commercial pressure booster applications using one-to-four VFDs, includes the VFDC-4000 controller and one VFD for each pump.
A new version of the patented Demand Limiting Controller (DLC) includes a number of advanced features such as fresh-air recirculation (based on occupied times, recirculation times, or CO2 levels), integrated management of multistage units, auto/off mode states, and enhanced auto-demand response.
The WattNode Revenue line of electric power meters are designed for use in applications requiring revenue-grade accuracy. The meters meet the accuracy requirements of ANSI C12.1 and C12.20 Class 0.5, and support Modbus, BACnet, or LonTalk® communications protocol.
Educational sessions at the 35th World Energy Engineering Congress, held Oct. 31 to Nov. 2 at the Georgia World Congress Center in Atlanta, covered a broad range of energy-related topics. Two of particular interest to the HVAC industry included energy management and building commissioning.
