Factory speed settings are in Bold
Air fl ow values are with dry coil and standard fi lter
For wet coil performance fi rst calculate the face velocity of the air coil (Face Velocity [fpm] = Air fl ow [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.
