Fig. 1 and Fig. 2 show the front view and the back view of BRT-706 speed control switch respectively.
As shown in Fig. 1 and Fig. 2 BRT-706 speed control switch has a Rotary knob on the front and wiring terminal blocks on the back.
BRT-706 speed control switch requires both hot wire and neutral wire for installation:
Hot wire (ACL): Coming from the power line with 220V;
Neutral wire (ACN): Usually coming with the hot wire; and
Load wires: Going to the load.
Warning: Please make sure power is turned off before starting installation!
Fig. 3 shows the wiring diagram and Fig. 4 shows the step-by-step installation instructions. There are three easy steps:
Step one: Use a screwdriver to pry off the front plate in position A;
Step two: Wiring according to the diagram and the labelled ports of the switch; and
Step three: Install screws and front plate.
BRT-706 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 -706 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.
BRT-706 speed control switch is ideal for regulating all kinds of motors especially for high power motor loads. It has wide applications at various locations such as homes schools laboratories hospitals bar restaurant etc to control the speed of ventilation fans pumps or blowers.
