1. A processor-controlled method of calibrating a controller for a door closer, the method comprising:

  • determining a plurality of arm positional values being output by an arm encoder coupled to an arm of the door closer, each arm positional value corresponding to an angular position of the arm;

    activating a motor to move a valve in the door closer to one of a plurality of positions;

    determining a valve positional value being output by a valve encoder coupled to a valve of the door closer to produce a plurality of valve positional values, each valve encoder value corresponding to a position of the valve; and

    storing the plurality of arm position values and the plurality of valve positional values in a memory within the controller for use during normal operation of the door closer.
