BRT-704 Installation Guide
Operation Guide:
BRT-704 speed control switch delivers stepless smooth control, and the speed is adjusted by using
the rotary knob on the front.
Turn on or turn off:
Rotating the knob clockwise away from the “OFF” position will turn on
the motor at its last speed and the fan is always turned on at the highest speed. Rotating the knob
counter-clockwise to the “OFF” position will turn off the motor.
Adjust the speed:
Rotating the knob clockwise will decrease the speed, and rotating the knob
counter-clockwise will increase the speed.
Adjust the minimum speed:
For the first time operation, adjusting the minimum speed may be
necessary for some motors, or the motor may not move due to too low a driving voltage. There is a
fine tuning dial on the side of BRT-704 speed control switch, as shown in Fig 5. This dial is used
for adjusting the minimum speed.
First, set the fan speed at minimum using the front rotary knob. Then, rotate the dial to yield a
minimum speed as desired.
