Below are each of the properties and description of each.
stageUp (bool or obj) - if true, the block will increment by 1 (make sure stageDn is false for it to work)
stageDn (bool or obj) - if true, the block will decrement by 1 (make sure stageUp is false for it to work)
holdStage (bool or obj) - if true, the block will hold the current number of stages
stageUpDelay (number or obj) - duration number for stage up time delay in seconds (for 1 min put 60)
stageDnDelay (number or obj) - duration number for stage down time delay in seconds
minStages (number or obj) - minimum number of stages to decrement too
maxStages (number or obj) - maximum number of stages to increment too
