We have a Lennox Heating & Air Conditioning Unit.. The later was just installed beginning of May. We're in the learning stages of trying to find a Happy Medium and Benifical Settings for the Central Air.. We shut the Unit off as there was a condensation buildup on the Plenum leading out from the main unit. The Operating Manual was soaked non the less.. The Mrs. Set the Touch Screen Control Settings , Cool To 17'C / Heat To 12'C ... Inside Humidity read 44%.. Thoughts & Opinions Appreciated, Cheers Thanks..
