Page 43: Understanding The Standard Ecm Nine-Tap Blower Motor Speed Selections
Figure 22: JHE unit wiring to multi-stage AC Figure 23: JHE unit wiring to HH8 heat pump Understanding the standard ECM nine-tap blower motor speed selections JHE and JME standard ECM air handling units use a blower motor programming strategy that provides nine different torque (speed) selections instead of the standard five speeds. - Page 44 If there was a simultaneous 24 VAC input on tap 2 and tap 3, the motor would operate on the torque (speed) programmed for tap 6. As another example, if a nine-tap standard ECM motor has simultaneous 24 VAC input signal on taps 1, 3 and 4, the motor would ignore the input on tap 1. Tap 3 and 4 would take priority and the motor would operate on the torque (speed) programmed for tap 8.
