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.
The KL6781 M-Bus master terminal gathers data on energy consumption in building automation solutions. The master terminal extends its range of energy measurement terminals; electricity, water, gas, or energy meters with M-Bus interfaces can be integrated into the firm’s fieldbus-independent bus terminal system.
With the EE771, EE772, and EE776 thermal flowmeters, users can record the mass flow or corrected volume flow in the supply network with the highest possible precision, regardless of pressure or temperature. For example, consumption of compressed air, nitrogen, helium, CO2, or oxygen can be measured.
The Power Xpert® Gateway 200E gateway collects energy usage data from meters, enabling customers to benchmark energy usage, set energy management goals, determine the effectiveness of energy management initiatives, and reduce their energy costs.
Both the AquaGuard AG-1100E and AG-1175E are electronic condensate management sensors for metal secondary drain pans. They mount directly to the side of a metal secondary pan in seconds with a single thumbscrew, making any installation — commercial or residential — quick and easy.
The Flood Buzz™ Pro is an easy-to-use, to-the-trade-only, low-cost, patent-pending, and effective water leak alarm. It is designed to help mitigate damage caused by water leaks and to serve as a key marketing and relationship building tool for plumbers, HVAC contractors, insurance agents, remediation contractors, and more.
Including a wide range of models, the ECL Series programmable controllers use LonWorks 2.0 technology, providing significantly faster operating speeds and additional functionality. The LonMark-certified products offer a robust, powerful, and feature-rich hardware platform.
The Acclimate 2251TMB photoelectric detector includes thermal detection at 135°F. It uses advanced onboard software to combine the signals from the photo and thermal elements to create a true multicriteria detector that responds quickly to real fires while rejecting nuisance alarms.
