4. ON Il UNIT OPERATION Basic Operation Controlled humidification requires a very precise control system The Herrtronic AD utilizes a solid state control to monitor performance and maintain humidity Further the Herrtronic AD evaluates the operation and alerts the operator to problem conditions and prevents undesirable operation 1 Start up On initial start up prompted by the humidistat the fill valve opens allowing water to enter the cylinder When the water level rises to the electrodes current will flow and the water will begin heating As the water temperature rises its conductivity also increases accelerating the rate of temperature increase When the output reaches the capacity set point the fill valve closes The output capacity may continue to rise slightly beyond the capacity set point As the water boils the water level falls with resulting output reduction 2 Normal Operation Upon achieving capacity set point the system begins operation in a steady state mode Output capacity slowly decreases until the elapsed cycle time opens the fill valve to replenish the water level until the capacity set point output is achieved As the mineral concentration in the water increases the water conductivity also increases Accordingly the rate of boiling increases Eventually the rate of boiling reduces the output capacity below the low drain threshold before the cycle time initiates the fill cycle At this
