In last month’s article, I discussed the three stages of building integrations.

I remember sitting in at a conference (I won’t mention which one to preserve anonymity), and the speaker was talking about “systems integration.” 

Are your sequences state based? Is there a finite set of conditions that drives your control sequences? If not, you may be missing out on one of the most intuitive ways to write control sequences. 

Last month, I started to explore when to use simple sequences and when to use complex sequences. Part of creating the correct sequence lies in the proper use of technology. 

It’s the heating season here in North America and that means building operators and controls contractors will soon be scrambling to ensure their heating systems are working properly. 

The control systems we use in commercial buildings today have evolved over the last 30 years to provide systems that are cost effective, and provide good performance. 

Carrier introduced its new TruVu™ multi-purpose control (MPC) platform for monitoring and control of HVAC equipment. The control platform consists of a TruVu™ MPC processor, featuring built-in BACnet routing and integration capabilities, along with expansion modules that can be added to support up to 180 total input/output (I/O) points for a variety of HVAC applications.

Greenheck’s latest addition to its line of Vari-Green® energy control products is the VGD-100+ internal variable frequency drive.
