The HH-6705 Series Duct Humidistat is typically mounted downstream from a humidifier, and turns the humidifier off (contact opens) when the setpoint is reached. Setpoint is adjustable from 30 to 90% Relative Humidity (RH). To reduce equipment cycling, the HH-6705 Series turns the humidifier back on (contact closes) when the humidity in the duct falls 5% below the setpoint.
