I am new to commercial controls and I have a few questions:
(1) I have a VAV box with a series fan and hot water re-heat the current setup is for a 1000 cfm box. Max airflow is set to 600 cfm. They set it up originally in Tracer for the min cooling and min heating the same. My question is how do you know what to set the max airflow, min cooling and min heating. I always thought the min heating was supposed to be lower with hot water reheat. Does the series fan pulling plenum air have something to do with setting the min cooling and heating the same?
