PRINCIPLES OF OPERATION
The Steam Humidifier delivers humidity in the form of steam to the conditioned space via the HVAC system duct or optional Model
Steam is delivered into the airstream through a dispersion tube mounted in the HVAC system ductwork.. Openings in the dispersion tube are fitted with “tubelets” which extend into the center of the tube.. The design of the dispersion tube and tubelets distribute steam over a wide area in the duct and direct any condensed moisture back into the steam hose..

SEQUENCE OF OPERATION
When the Humidifier Control detects humidity below the set point, and provided the humidifier is turned on and the indoor unit blower is operating, the internal controller in the humidifier energizes the electrodes and measures the current flowing through the water between them.. The controller adjusts water level in the canister via a fill valve and a drain valve to maintain a constant current.. The operating water level in the canister depends on the mineral content of the water which determines conductivity..
A relay is provided with the humidifier that will allow the control to turn on the indoor unit blower when a call is made for humidity..
