Where should a humidity sensor be placed in a room?

The mounting location should be in a sheltered area that is protected from rain. Ideally, the transmitter should be located on the north-side of the building (under an eave) to prevent sun-heated air from rising up the building’s wall and affecting the relative humidity of the sensor.

Can you use a regular switch for a bathroom exhaust fan?

If it’s a typical small one speed bathroom fan you can use any on/off switch that matches the load specs; just don’t use a dimmer switch intended for lights. If it’s a large ceiling fan or a variable speed fan, then you need to use one of the purpose – built fan switches: both Leviton and GE make these.

What is a humidistat switch?

The Humidistat Humidity Switch is a hard-wired humidity sensor that can be used with all Sensaphone models to detect high or low humidity levels. Users set a high or low alarm limit by adjusting the dial on the front of the sensor.

How does a humidity switch work?

Humidity sensors work by detecting changes that alter electrical currents or temperature in the air. There are three basic types of humidity sensors: capacitive, resistive and thermal. All three types will monitor minute changes in the atmosphere in order to calculate the humidity in the air.

What does adjustable humidistat mean?

A humidistat (sometimes called a humidistat control) is a device that works with a home’s heating and cooling system to automatically adjust the amount of moisture in the air to maintain a specific humidity level throughout the home.

What is the best setting for a humidistat?

healthy indoor humidity level is somewhere between 30-55%. More specifically, most homeowners find that a setting between 35-45% achieves the best results. by a few percent levels.

Are humidistats interchangeable?

It’s not unusual though to find stand-alone small humidistats that act more like hygrometers, simply for monitoring purposes. Sometimes these two terms (humidistat and hygrometer) are used interchangeably.

What is a humidistat connected to?

Whole-House Humidistats

In whole-house systems, dehumidifiers or humidifiers are connected with the central HVAC system. In such systems, the humidistat is also responsible for adjusting the dampers, valves, or other HVAC system switches to regulate the airflow as well as the humidity throughout your home.

What is the difference between a hygrometer and a humidistat?


A hygrometer is a device that monitors or measures the amount of humidity in the air. Its only function is to provide a reading of the amount of moisture in a space. On the other hand, a humidistat is a device that is incorporated into an appliance and is used to control the humidity levels in a room.

What is the difference between a humidistat and a dehumidifier?

Humidifiers add moisture to the air when it is too dry. Generally, people use humidifiers in the wintertime to combat the dryness of winter air. A dehumidifier takes moisture out of the air when it is too humid. Dehumidifiers are used during the spring and summer.

How do I know if my humidistat is working?

Turn the humidistat to a very low setting or to “off.” The multimeter should register no voltage. Then, turn the humidistat to a very high setting, such as 80 percent relative humidity, or until you hear a “click” sound. The multimeter should register about 24 volts if the humidistat is functioning correctly.

Should humidistat be off in summer?

What Should My Humidistat Be Set at in the Summer? While everyone’s home comfort preferences will vary, we recommend a humidistat setting between 35 and 45 percent for Summer.

When should I turn on my humidistat?

When the outdoor temperature is near 0 degrees, use a humidistat setting of 25 percent. For outdoor temperatures around 10 degrees, set the humidistat to 30 percent. At an outdoor temperature around 20 degrees, a 35 percent humidistat setting is appropriate.
