I have a Bryant Evolution Control Thermostat (SYSTXBBUID01-B). I've noticed while running the Air Conditioner the condenser comes on sooner than it should. For example, the temperature is set to cool at 79 degrees; the actual temperature shown on the thermostat reads 77 degrees, yet the condenser periodically runs. Is it running to keep the humidity at a certain rate, causing the temperature to go below the programmed temperature setting? I’m just guessing. The thermostat and HVAC system are less than a year old.
Your answer would be greatly appreciated.
Thanks.

If set to de-humidify, the stat can overcool by 3 degrees. See installation instructions.
