A simple approach is the future of building automation systems

Thanks to improved wireless networking technology and standardized communication protocols, it’s easier than ever to collect data from sensors. Plus, silicon chips continue to get cheaper, faster and better and can be located in valves, actuators, thermostats and wall outlets to provide more memory and faster computing. With the Internet of Things (IoT) continually expanding […]

Controls and Cables in Environmental Air Handling Spaces, Ducts, and Chases

First, let’s discuss controls and their enclosures in air handling spaces, ducts, and plenums. Many times, we have to install items in these spaces and it’s important to consider that anything we put in there should either be non-combustible (metal) or else be listed under UL 2043 for use in air handling spaces. The NEC […]

THE (RS-485 Network) TERMINATOR Or The Dance of the Data Pulses

If you’re involved with building automation systems you know (unless you’ve been living under a rock like the guy in that insurance commercial) that the modern trend is to connect all your building controls together on networks. Networks make it easy to add or move control nodes as your building control needs change since the […]

What Are Power System VARs?

Most people involved in building automation are familiar with kW, which is the rate at which a building is consuming energy from the power company. But there is another power system parameter known as VAR/kVAR which is less well understood. In this article we will attempt to dispel some of the VAR mystery. The term […]
