On traditional programmable or older digital Honeywell thermostats, the three buttons beneath the display typically serve dedicated control functions: The left button (often labeled System) switches operating modes between Heat, Cool, Auto, and Off. The middle button (often labeled Fan) controls blower operation between Auto, On, and Circulate settings. The right button (often labeled Run, Hold, or Menu) manages schedule overrides and accesses programming menus.
