Modulation Options for Boiler Controls - RL Deppmann
Oct 12, 2009 · 2) Progressive Modulation is a combination of Series and Parallel. The lead boiler will start, and modulate up to something less than (i.e. 80%). Once the lead boiler hits 80%, the second boiler will fire to 40% and the lead boiler will decrease to 40%. As the load increases, both boilers will increase up to 80%.
