Humidistat
What it is
A wall-mounted humidistat control is recommended to measure room RH and reduce dehumidifier short-cycling.
Hygrometers, available at local hardware stores, may be used to measure humidity levels. Some humidifiers contain a built-in humidistat which may be adjusted to the proper moisture level.
All ENERGY STAR dehumidifiers include a built-in humidistat, a device that allows you to set the desired RH level that you would like for the room. Once the room reaches the desired RH level, the dehumidifier will cycle on and off automatically to maintain the level.
The latent load is the heat associ- ated with airborne moisture as measured by a hygrometer or humidistat.
