ECM Essentials

February 23, 2021

HVAC Contractors, HVAC Technicians

Knowing which mode to use when commissioning an ECM is very important. We all understand that we should “do the math”, but at midnight in the middle of winter we just want to get the “heat back on”! It would be nice to have that circulator set up in the correct mode. In this program, you’ll learn about the different operating modes of ECM circulators, and how to select the mode that works best for the many different applications you’re likely to see.
