– System 3: Supply air humidity control with continuous output limitation
Supply air humidity control (humidity sensor installed in supply air duct) should be used
only where room humidity control is impracticable for technical reasons . Such systems always
require a PI­controller.
The humidity sensor (A1) is located in the supply air duct after the steam distribution pipe. The
humidity sensor (A2) for the continuous output limitation is located in the supply air duct before the
steam distribution pipe. Such a system requires the internal PID controller or an external PI­controller
with the option to connect a second humidity sensor.
Which humidity control system for which application?
