Door closer with teach mode

Apparatus for teaching control circuitry for a door closer values for a door to be used in controlling the door closer, the apparatus comprising:

• means for reading a user interface to determine an installation configuration for the door closer;
• means for monitoring a position of the door as the door moves in order to determine a swing for the door;
• means for monitoring the position and movement of the door in order to determine when the door is at a jamb position;
• and
• means for storing values regarding the installation configuration, the swing and the jamb position in the control circuitry to be accessed by a controller for use in controlling the door closer.

A controller for a door closer comprising:

• a position sensor to determine a position of a door;
• a user interface to provide information regarding an installation configuration of the door closer;
• a memory to store values regarding at least the installation configuration, a swing, and a jamb position for the door;
• and
• control circuitry having a teach mode, the control circuitry functionally connected to the position sensor, the memory, and the user interface, the control circuitry operable in the teach mode to read the user interface to determine the installation configuration, to monitor position and movement of the door in order to determine the swing for the door and when the door is at the jamb position, and to store the values in the memory.

A door closer having a teach mode, the door closer comprising:

• a spring;
• a movable element configured to move in response to movement of a door, the movable element loading the spring;
• a valve configured to control movement of hydraulic fluid around the movable element;
• a position sensor to determine a position of the door;
• a user interface to provide information regarding an installation configuration of the door closer;
• a memory to store values regarding at least the installation configuration, a swing, and a jamb position for the door;
• and
• control circuitry functionally connected to the position sensor, the memory, and the user interface, the control circuitry operable in the teach mode to read the user interface to determine the installation configuration, to monitor position and movement of the door in order to determine the swing for the door and when the door is at the jamb position, and to store the values in the memory for use in controlling the valve.
