Patent ID: 8773237

Claim:
A method of operating a controller for a door closer in a teach mode, the method comprising: determining that the teach mode has been entered; reading a user interface to determine an installation configuration for the door closer; monitoring a position of a door as the door moves in order to determine a swing for the door; monitoring the position and movement of the door in order to determine when the door is at a jamb position; storing arm gear values separated by a specified time interval in the controller as the door moves; determining by the controller whether the door is mounted for left handed or right handed opening based on the stored arm gear values; storing values regarding at least the installation configuration, the swing, whether the door is mounted for left handed or right handed opening, and the jamb position in the controller to be accessed by control circuitry in the controller; comparing the stored values to stored calibration curves, wherein the stored calibration curves independently profile opening motion and closing motion of the door; and skewing at least one of the stored values for use in controlling the door closer in response to the comparing of the stored values to the stored calibration curves.
