ABSTRACT:
A cycle control timer unit in which a rotatable annular program carrier is provided having two opposed sides, each formed with a different range program scale and having a different drive coupler means. The unit includes two different rotary drive transmission wheels facing in one direction and rotated at dissimilar speeds respectively adapted for drive connection with the drive coupler means. By flipping over the sides of the program carrier in the unit and connecting the appropriate drive coupler and drive wheel, an operator may easily switch between the different program ranges for control of the unit.
