It is back to school for Johnny Tundra, who returns to Rosebud County Vo-Tech. A chiller keeps tripping offline on high head pressure. How can the chiller have any load on it when the temperature outside is 15°F? Lead designer Jerry Seltzer is ready to replace the chiller, fire the mechanical contractor, and sue the controller provider. Fortunately for everyone involved, Johnny has an advanced degree in troubleshooting.

When fully utilized, Building Management Systems (BMS) offer facility managers many advantages. Harnessing building data to help correct root-cause energy inefficiencies is one area that is increasingly important yet challenging. This paper shows how leveraging BMS data through building data analytics software and combining it with expert engineering services creates actionable intelligence that can reduce HVAC energy costs by up to 30%....More
Though not required until December, 2022, the new UL 60335-2-40 standard is currently active for matched and packaged air conditioners/heat pumps (no standalone systems), liquid chillers and hydronic fan coil units, hot water heat pumps, dehumidifiers and supplemental heaters (designed as part of an appliance package).
A lot of leading building automations systems (BAS) are touted as being open. But what does that really mean? And does being open mean that building owners and operators are getting the most out of their BAS investments?
During this webinar, Johnson Controls BAS experts will examine the definition of openness and advise on what to look for from a BAS provider when secure interoperability and ease of integration is paramount. Because a unified intelligent infrastructure provides better interoperability so businesses run more efficiently....More
