BT asked if i had a straight supply truck to test, sadly no. so once again today i tested fan only on hi and low, then turned on heat for temp rise method
by tesp/blower curve= hi speed, 1.0"wc tesp ~850-900 cfm as im off the chart.
by 416 traverse in drop = high sp= 1038 cfm
by temp rise method = 1042 cfm
on low speed, tesp/ bc = 0.71"wc and 515 cfm
by 416 traverse in drop = 849 cfm
by temp rise method = 912.
my head hurts, if didnt have to go to work in an hour, id have a beer.
