What happens to the humidity levels if the humidistat is incorrectly set too low?

When a humidistat is set too low, it can lead to potential discomfort due to dryness in the indoor environment. Humidistats are designed to regulate the level of humidity in the air, and if the setting is too low, the system will remove more moisture than necessary from the air.

Dry air can cause a variety of discomforts, such as dry skin, irritation of the respiratory tract, and challenges for individuals with allergies or asthma. Comfortable humidity levels usually range between 30%-50%. If the levels drop below this range due to incorrect settings, it leads to an excessively dry atmosphere, which can be unpleasant for occupants.

The other options do not accurately describe the consequences of a low humidistat setting. Increased comfort levels and improved air quality would not occur because dry air does not foster a comfortable living space. Similarly, while reduced energy consumption might be a possible outcome of running the system less frequently due to lower humidity levels, this is not a direct benefit nor the primary concern associated with discomfort from dry air.
