a control device that can be connected to an HVAC system and adjusted so that if the humidity level rises above a set point, the HVAC system will automatically turn on and reduce the humidity below the established point
a device that monitors the humidity in the room and automatically turns on or off the humidifier to achieve the desired humidity level
a device that senses the humidity in the environment
a device used to control the operation of space conditioning systems such as air conditioners, dehumidifiers and humidifiers
A device which turns a switch on and off based on the humidity of the room. The switch controls a humidifier unit, which supplies needed humidity to the air, and then switches off when the humidistat senses that there is enough humidity.
A control "thermostat" which senses relative humidity instead of temperature. (Lull, 91)
A humidity-sensing control that cycles the humidifier on and off.
An automatic device used to maintain humidity at a fixed or adjustable set point.
Thermostat-like device that measures the amount of water vapor in the air and turns a humidifier or dehumidifier on and off accordingly.
The device that measures humidity and turns the humidifier on and off.
a control switch used to operate (turn on and off) another device based on pre-set humidity conditions
A device designed to regulate humidity input by reacting to changes in the moisture content of the air. Much like a thermostat but turns the system on & off by sensing the humidity level.
Controls the level of humidity put out by a humidifier. Not always necessary on a "cool mist" humidifier; essential on a "warm mist" humidifier to prevent over-moisturizing a room.
A regulatory device, actuated by changes in humidity, used for the automatic control of relative humidity.
