Systems, components, and methods for operating movable barrier operators in a headless mode

A method of adjusting an operating mode of a movable barrier operator, the method comprising:

• detecting, via control circuitry of a movable barrier operator, operable communication with a wall controller, wherein the wall controller is electrically coupled to wall controller inputs of the control circuitry through a wall controller input circuit;
• controlling, with the control circuitry, a motor of the movable barrier operator to operate in a first operating mode in response to operable communication with the wall controller;
• detecting, via the control circuitry, a loss of communication with the wall controller;
• and
• adjusting, with the control circuitry, the motor to operate in a second operating mode in response to the detecting the loss of communication with the wall controller, the second operating mode different than the first operating mode.

A method of adjusting an operating mode of a movable barrier operator, the method comprising:

• controlling, with a control circuitry of the movable barrier operator, a motor of the movable barrier operator to operate at a first operating speed, the first operating speed being less than a second operating speed of the motor, wherein the movable barrier operator comprises wall controller inputs configured to be in communication with a wall controller input circuit in communication with a wall controller, wherein the wall controller inputs comprise a first terminal and a second terminal;
• detecting, via the control circuitry, a short between the first and second terminals from a user override;
• and
• adjusting, with the control circuitry, the motor to operate at the second operating speed in response to detecting the user override.
