Responded to warranty call regarding temperature control issues with recently installed HVAC system. Upon inspection and analysis, determined system was functioning as programmed rather than experiencing mechanical failure. Thermostat was configured to prioritize humidity control at 50% relative humidity target, allowing up to 3 degrees of overcooling below temperature setpoint. System was actively overcooling second floor based on thermostat location while causing excessive cooling in attic space. Recommended disabling overcooling function to maintain more consistent temperature control. Proposed installation of new thermostat with wireless sensor capability to enable temperature averaging between second floor and attic locations.
