Auto Changeover Mode
Auto Changeover mode is a feature enabled/disabled in the Installer Settings
(see Installer Manual). If enabled, it is selected by pressing the SYSTEM button
until AUTO HEAT or AUTO COOL appears in the display.
When Auto Changeover mode is enabled and selected, the system automatically
switches between heating and cooling when the room temperature meets the
programmed heating or cooling set points. To operate properly, the thermostat
requires a “dead band” setting to eliminate program conflicts. The dead band is set
in the Installer Settings (See Installer Manual). The default setting is 3° F. Therefore,
you will not be able to set your heat or cool temperature within 3° F of each other. If a setting is made in either
heating or cooling which violates the dead band, the opposite mode will adjust up or down automatically to
maintain the programmed dead band spacing.
