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.
