Notes:

1. All RTN pins are internally connected.

2. Meter function is to copy either of hall sensors.

3. Switch to 12V is active. Open switch is inactive.

4. F-N-R control and three speed function can not be used at the same time.They both

used the same pin as pin12=FWD

Pls. contact with sales first if you don't know how to connect the controller with motor and other parts.

5.Questions before order

1). If you want to buy the controller separately, please advise us the parameters of your matching motor?

Such as Motor Voltage, Wattage, Speed...

2). If you need any other special functions for this controller, please feel free to contact to us. Thank you!
