Michel, Update: First one still has issues in Auto mode with humidity sensor. Upstairs unit V2.2 Build 1310 Receive new thermostat for downstairs unit today and it appears to work perfectly with sensor (removed humidity sensor from upstairs unit). Downstairs unit V2.20 Build 4010 Set upstairs in auto and it reports humidity as double the set cool temp Bad thermostat firmware version? Greg

Michel, It is a Rev. 2.2, it is the integrated 7-day thermostat. Greg

All, I have had the same issue, one thing that I tried was to select "cool" instead of "auto" and the problem clears. Once I select "auto" again then I get a humidity value to be double the cool temp setting. Greg Isy-99i 2.8.16 T1800
