Fan Speed
FAN SPEEDThe fan speed increase/decrease knob is used to manually change fan speed. Turning the fan speed knob in the increase (clockwise) direction one detent increases fan speed one level. Turning the fan speed knob all the way in a clockwise direction will increase the fan speed to the maximum.
Turning the fan speed knob in the decrease direction will decrease fan speed in the same manner as increase.
If the system is operating under "AUTO" fan speed control, turning the fan speed knob in either direction, causes AUTO" fan speed control to stop and manual fan speed control to begin. Fan speed remains constant, unless the speed control knob is turned again.
With the system in "OFF" mode, turning the fan speed knob in a clockwise direction causes the system to turn on in the "AUTO" mode with "AUTO" fan speed control.
