Interface definition:
Red wire: input port connected to 220V fire wire
Green wire: input port connected to 220V zero wire
Yellow wire: output port 220V fire wire
Working Principle: After energizing the switch 220V, the switch opens and at the same time outputs 220V fire wire to power the appliance, after a time delay, the switch closes and stops outputting when the time is up, thus the appliance stops working.
Working uses:
1, exhaust fans, motors, cooling fans, germicidal lights, humidifiers, heaters and other appliances automatically shut down at regular intervals.
2, kitchen, bathroom, toilet, bedroom and other exhaust fan switch off after the exhaust fan continues to work for a period of time automatically shut down (combined with a double switch to achieve power-off delay off function - refer to wiring diagram 3).
Note: 1, after the switch delay time, the indicator will flash prompt.
2, after the delay time to the following start again need to disconnect the power supply for more than 2 seconds to wait for the remaining power to run out before restarting
Use the operating procedure:
1, first select the switch delay time, through the cross screwdriver clockwise according to the scale to select different delay parameters.
2, disconnect the power supply of the device and other electrical connections to avoid wiring electrocution.
3, according to the above wiring diagram, connect the circuit, and wrap the electrical tape.
4、After checking the wiring without problems, turn on the power, the appliance will work normally and will automatically turn off when the time is up and the indicator light will flash.
