A user-programmable monitoring and dispensing system for controlling the dispensing of water vapor and various other media into an HVAC air stream in residential or commercial structures. The various media to be dispensed are preferably water-soluble, and mixed with the system water supply to be dispensed with the water vapor added to the HVAC air stream. These materials may be fragrances or aromas, intended to produce an aesthetic effect, or they can be agents capable of pesticidal, bacteriacidal, fungicidal or sporacidal effect for use as acute or prophylactic treatment for infestation. The dispensing system central processor is pre-programmed with a default concentration algorithm for each media to be dispensed. The concentration of media in aqueous solution is initially controlled by this default algorithm at each of several concentration levels, from lowest to highest. After being exposed to the air containing the dispensed media at a medium concentration of the default algorithm for a default time period, the user may indicate, via a data entry/display, whether the perceived concentration is higher or lower than that desired. This input from the user to the central processor acts to replace the default concentration algorithm with a new, preferred algorithm wherein the scale of media concentration is shifted to correspond to the user's preference.
