Does it lower your relative humidity as measured by the thermostat or HVAC controller?
I have programmed commercial controls for HVAC. Heater controls are based on temperature and relative humidity. No dehumidifiers needed for human comfort in most regions. They are needed for controlling the environment in sensitive areas such as a laboratory or computer/server rooms.

I assume that it lowers the relative humidity or the AC would never shut off. As I said, I never use the dehumidify feature because the relative humidity in my house is always below 60 percent, and usually below 50 percent. The only advantage I can see for using the dehumidify feature is to raise the thermostat setting to 80 degrees or higher while the house is unoccupied to save money on electricity. But ideally, to control both the temperature and the humidity, you need a reheat function, which many HVAC units do not have.
