This door comes without a door controller. Below is a schematic diagram which shows how to connect your door controller to the connector wiring for the motor and limit switches:

Your door controller will need to handle power to the motor to open and close the door.

• Motor Operating Current: 300 milliAmps (0.3 Amps)
• Max motor current (deadlock): 1,200 milliAmps (1.2 Amps)

Door controller will need to be capable of providing sufficient current to power the motor and should also limit current to prevent overheating of the motor windings, leading to motor failure.
