    time duration and an “

    off”

    time duration, and wherein each of the plurality of scent delivery units is associated with a corresponding base scent setting; and

    a central controller configured to control the plurality of scent delivery units, wherein controlling the plurality of scent delivery units includes;

    defining a group of scent delivery units from the plurality of scent delivery units,receiving input indicating a scent level bias to be applied to the base scent setting of each scent delivery unit included in the group for a particular activation period, andgenerating command data for each scent delivery unit included in the group, wherein the command data is generated by applying the scent level bias to the base scent setting using a predefined algorithm, wherein the predefined algorithm modifies the base scent setting using the scent level bias, and wherein when the command data is received at a scent delivery unit included in the group, the corresponding scent level of the scent delivery unit is varied based on the generated command data.
