An apparatus for effecting actuation of a positioning member and a method for commissioning the apparatus wherein the apparatus includes a controller coupled to a drive motor and adapted to receive an input signal and to apply positioning signals to the drive motor. The positioning signals selectively effect positioning of the positioning member and determine a first position and a second position of the positioning member. The method for commissioning the apparatus selectively includes performing an end stop determination sequence in response to an end stop determination signal, winding a bias member, and determining a range of rotation for the positioning member. The end stop determination sequence seeks to detect the presence of both a load and spring when rotating the positioning member and biasing member, respectively, in one of a first and second direction. The load and spring are detected, if present, by monitoring the rotation of the positioning member and bias member, respectively, to detect a stall before the positioning member and biasing member, respectively, exceed a predetermined position. Similarly, during the wind spring sequence and range sequence, the rotation of the biasing member and positioning member, respectively, are monitored for a stall that indicates that the biasing member is cocked and the end stop of the positioning member is determined, respectively.
