How do I adjust the temperature on my Honeywell thermostat?
Use the Up (∧) and Down (∨) arrow buttons located on the right side of the thermostat to adjust the desired set temperature. The digital display will show both the current room temperature and your set temperature simultaneously, making adjustments simple and intuitive.
