Factory speed settings are in Bold
Air flow values are with dry coil and standard filter
For wet coil performance first calculate the face velocity of the air coil (Face Velocity [fpm] = Airflow [cfm] / Face Area [sq ft]).
Then for velocities of 200 fpm reduce the static capability by 0.03 in. wg, 300 fpm by 0.08 in. wg, 400 fpm by 0.12in. wg., and 500 fpm by 0.16 in. wg.
Highest setting is for auxiliary heat (W) and lowest setting is for constant blower (G). The "Y1" and "Y2" settings must be between the
"G" and "W" settings.
Setting Blower Speed - 5-Speed ECM
5-Speed ECM blower motors have five (5) speeds of which three
(3) are selectable on single speed and four (4) are selectable on
dual capacity.
CAUTION: Disconnect all power before performing
this operation.
