– 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PI-controller.
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aPI-controllerwiththeoptiontoconnecta
second humidity sensor.
