Pressurized steam is introduced through a steam control valve into a heat exchanger submerged ® in water. The valve modulation is controlled by an electric actuator. The INTAC will control the electric actuator with an analog control signal to modulate the amount of steam entering the heat exchanger which will in turn control the amount of steam production on the outside of the heat exchanger.
Page 11: Intac
The process the ® INTAC goes through to accomplish this is called the Automatic Timed Drain. By default the humidifier begins counting run time whenever the humidifier output is greater than 0%.
Page 12: Pid Control Loop Tuning
PID CONTROL LOOP TUNING For most humidification applications, the parameters in a humidifier control loop that are based off of a room humidity sensor or return air humidity sensor should be set so that the % demand signal changes relatively slowly. This is due to the high thermal inertia involved with boiling water.
Page 13 ® humidistat when the supply air temperature or volumetric flow are change abruptly. The INTAC is always comparing the room/return air humidity and the supply air humidity and choosing control loop the results in the lowest power level.
Page 14 Low range limits are set correctly. If a slight calibration is desired, proceed as follows: ® First, determine if the INTAC indication is too high or too low and by how many degrees. This can be checked by using a probe-type thermometer located near the air temp sensor and comparing the readings.
