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 conicts. 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.
