The standard builder's Carrier thermostat has a dehumidify setting. If you use this optional setting, the air conditioner will "overcool" the house by about 3-4 degrees when the humidity is higher than the dehumidify setting. So, if your thermostat is set at 80 degrees, your system may cool the house down to 76 when the humidity is high, but not when it is low. The dehumidify setting is good to use if you are a snowbird and you want to set your a.c. temp very high. But, I don't think it is normally needed and may cause your house to get too cold.
