We have a Flair HVAC unit along with our ClimateMaster 27 geo system. The humidity setting really confuses me - perhaps someone has some insight. On the ClimateMaster, I only see settings for humidity offset. I can set this 0 or + degrees. The thermostat measures RH (relative humidity) which seems to fluctuate. Based on the settings for the HVAC unit, the Humidity ON seems to come on and the ClimateMaster fan seems to run. Changing the HVAC unit settings seems to control this setting. Does this make any sense? I didn't think these two were correlated? Sorry about my lack of knowledge but we inherited the HVAC unit and have little understanding of how it works.
