What happens when demand drops in a closed loop variable speed system? What is the operational sequence and what logic does the controller use to vary the speed of the pump? Let’s begin our discussion with the following...
Read MoreToday we begin a series of blogs exploring modern variable speed pump control. While we have written about variable speeding pumping in the past, we believe that the increasing presence of variable speed systems, along with the rapid evolution of control options, warrants a comprehensive look at variable speed pump control as a...
Read MoreThroughout our Hydronic Balancing Series, we’ve been slowly and meticulously making our way to the more complex control systems that we see today. We walked you through the steps of proportionate balancing a simple 3-zone system and taught you how to trim an impeller in accordance with ASHRAE 90.1. Today, we’re going to see what happens when we add variable speed drives to the system.
