I just got a new Lennox system installed today.

I got G60UHV furnace (dual stage, variable speed), XC14 A/C, and Honeywell IAQ thermostat. The install went pretty smoothly, but I'm not 100% sure if the techs hooked up the thermostat correctly as I saw them studying the installation manuals for a little too long.
I've had the A/C running for about 3 hours after they left and while the temperature has reached the set 74F, the system is off but the humidity is showing as 49% while it's set to 45%. Isn't the IAQ thermostat supposed to run the A/C at lowest speed blower setting until the desired humidity level is reached?
I haven't gone through the thermostat settings myself yet, but I'm wondering at this point if it's the wiring or the programming issue.
Thanks!
