Wall or Duct Mounted Modulating Humidistat: Provides a modulating signal to the unit that represents the
output (up to 100%) required from the humidifier. Signal type can be changed in the field.
All GS models may be configured for either single or dual channel modulation. Control signals can be 0-10
VDC or 0-20 mA (0-5 VDC, 1-5 VDC, 4-20 mA and 2-10 VDC are also available). The unit must be ordered
from the factory for the desired signal type and number of channels. When configured for 2-channel
modulation the humidifier will generate steam only if both channels indicate a demand. If both channels are
demanding steam the humidifier will satisfy the lower demand signal.
