Humidistats are old technology that cause too many problems. They works by overriding your thermostat and if set incorrectly can easily freeze up your inside coil and cause service issues. It is absolutley correct that humidity plays a big factor in your comfort level. I can be 70 degrees and if you have high humidity levels it will make you feel clammy. I would suggest an all in one themostat. honeywell makes a touch screen programmable thermostat that have humidity functions built in. very user freindly

So what you guys are saying is that a humidistat takes the place of or overides the system thermostat? Living in the south now I hate humidity.

Company that installed my HVAC said that if we're gone in the summer to install a humidistat and don't worry about temp in summer, humidistat will keep it at the right humidity which is what causes problems. They installed my humidistat for under $150 total.
