Humidity Set Point - (1/2 Proportional Band)
Note: in the above example that the control band begins at the 50% humidity set
point and has a length of 4%, which is ½ of the programmed humidity proportional
band value.
As the return air humidity decreases the infrared humidifier is activated at 46%RH
or 100% of the humidification control band. When the return air humidity starts to
increase, the infrared humidifier is deactivated at 48%RH or 50% of the
humidification control band.
