Setting the temperature setpoint in the low 80s and the relative humidity setpoint around 50-60% would be reasonable.

Why? Relative humidity is exponentially related to temperature and is also limited on how high it can go with hot temperatures. If the temperature in the house gets hot enough, you may never exceed the relative humidity set point. For example, if the temperature in the house was to reach 95F then the relative humidity will probably never exceed 60%. In this situation, the system will never come on but there could be a fairly high absolute moisture level (the dew point) in the house.



Good Post.
