1. Turn on or turn off the fan and adjust fan speed: Rotating the knob clockwise will turn on the fan and rotating the knob clockwise further more will reduce the fan speed. When the fan is on rotating the knob counter-clockwise will increase the fan speed and rotating the knob counter-clockwise further more will turn off the fan; and
2. Set the minimum fan speed limit: As shown in Fig. 4 the minimum fan speed can be fine-tuned by tuning a screw on the side of BRT-784 during initial installation. Turn on the fan and rotate the speed control knob to run the fan at the lowest speed. Then turn the screw using a screw driver to obtain a minimum fan speed as desired.

Note: Adjusting the minimum speed is necessary for some motors or the motor may not move due to too low a driving voltage.
