How to check and adjust parameters:
User parameter checking and settings (avail in both ON and OFF state)
In the main interface, press “ function” key for 3 seconds to enter user parameter checking and settings interface;
press “+” or “-” to check each parameter.
Press “ function” to enter current user parameter settings interface, press “ +” or “-” to modify the value, again
press “function” key to return to query status.
Under parameter checking or setting interface, if no operation to the controller within 30 seconds, the
controller will return to main interface automatically. The controller also can back to main interface via pressing
ON/OFF key.
Factory parameter checking and settings (avail in both ON and OFF state)
In the main interface, together press “ ON/OFF” and “ +” keys for 3 seconds to enter factory parameter password
interface. In this interface, press “ time” to switch code digits, press “ +” or “ -“ to modify the value of each digit,
and press “ function” key to input your password, if the password is correct, the controller will enter factory
parameter check interface. ( factory check password: 0814)
In the factory checking interface, press “ function” to enter current factory parameter settings, press “+” or “-“ to
modify the value of the parameter, and press “function” to return to query status.
Under factory parameter query or setting interface, if no operation to the controller within 30 seconds, the
controller will return to main interface automatically. The controller also can return to main interface via
pressing ON/ OFF key.
