What is a Humidistat? |

Answer:
A humidistat is a control device which Not all humidifying systems require a humidistat, but homes in relatively wet regions or near large bodies of water often benefit from the added humidity control. Some humidifers can add too much moisture into the air because they are not designed to shut off automatically. This extra moisture can lead to excessive mold growth in the home and water damage to the structure. A humidistat is set to a prescribed humidity level with a dial and if it reads a drop in air moisture it will send a signal to a centralized humidifier located above a furnace or a portable humidifier located in the room. When the humidity level is at an acceptable level, the humidistat turns off the humidifier and any forced-air fans used to introduce the water vapor into the room. Proper placement of a humidistat is very important, since the sensor needs to read the humidity level of the entire area. It is common to find a wall-mounted humidistat above an air return vent, because the moisturized air from the humidifier is often introduced into the room through that duct. A humidistat may also be mounted above the dampest point of a problem area, such as a wet basement or very humid attic space. A humidistat may work in tandem with a room thermostat, or it may be used in association with a dehumidistat, which activates a dehumidier if the room's humidity exceeds a prescribed level.
