With help from folks on this site, I've selected a Rheem HP and AH. I live in Northern VA where it gets very humid. I would like to have the system control humidity in my house. I've been told that I need an Honeywell IAQ thermostat to do this.
The HP and AH are:
RPQL-030JEZ + RHKL-HM3617 (RCSL-H*3617A*)
What Thermostat and sensors can I use to have the system automatically slow down the Air Handler to lower the humidity?
