COMMON TERMS AND WHERE TO FIND THEM

Auto changeover

This feature automatically switches your system from heating to cooling – or from
cooling to heating – whenever necessary when in auto mode only (heat/cool).
Auxiliary heat
(heat pump and Hybrid Heat systems only)
Most heat pump systems can't heat a home sufficiently when it gets very cold
outside so they use a supplemental heating source called auxiliary heat. The system
knows when to use this help and does so automatically. If it's using auxiliary heat,
the display will show auxiliary heat on when you press the mode button. You have
no control over the auxiliary heat function.

Backlighting

Backlighting illuminates your display. The backlight is on constantly at a dim level
that brightens when you push a button.

The thermostat will automatically change the clock according to daylight savings
time procedures twice a year.
