The webinar will explain the relative merits of two different approaches to flow modulation in boiler systems: variable primary and primary/secondary. It will look at the upsides and the downsides of each including the chiller sequencing, control of flow and return temperatures, pump control methods, by-pass control and any potential threats and vulnerabilities. Join us Tuesday November 17th for an in-depth discussion that will be of interest to building owners, developers, and HVAC system designers.
