Turn the humidistat to a very high setting, such as 80% relative humidity, or until you hear a “click” sound. The multimeter should register about 24 volts. If you show 24 volts at the connection from the humidistat to the solenoid, then the humidistat is operating correctly.

Similarly, how does a Honeywell humidistat work? While the thermostat on your air conditioner measures the temperature inside the home, a humidistat measures the humidity. If the temperature is high but the humidity level is low, the humidistat does not allow the air conditioner to run. This prevents using electricity to cool your home when you arent there.

Also to know, what does a humidistat measure?

A humidistat (sometimes also called a hygrostat) is a small measurement instrument or device that helps to monitor and maintain the set or preferred relative humidity in the air.

What should my humidistat be set at in summer?

So to be safe, we recommend setting your humidistats relative humidity (RH) to 58 percent and setting your thermostat temperature between 77 and 80 degrees Fahrenheit. These settings will not maintain your selected temperature indoors but will maintain 58 percent humidity.
