humidistat demand mode

In the humidistat demand mode, the humidistat will measure the

relative humidity of the space, compare the measured value with the

setpoint, and output a demand signal to the humidifier. The demand

signal in this mode can be either on/off or a modulating 0-10VDC.

When measured humidity is 3%RH above the setpoint, the demand

signal will be zero. When measured humidity reaches 3%RH below the

setpoint the demand signal will be 100%.

The modulating 0-10VDC humidistat output corresponds to the demand with

0VDC at 0% demand and 10VDC at 100% demand. The ON/OFF humidistat

output will turn on at 100% demand and will turn back off at 0% demand.
