Auto Changeover; Smart Recovery - Carrier Performance Edge Owner's Manual

Auto changeover
The thermostat displays one of five modes: heat, cool, Em heat (heat pump
version only), heat cool (auto mode) and off. When the mode selection is for
both heating and cooling - auto mode - the thermostat is in auto changeover
mode. This allows the system to switch from heating to cooling - or from
cooling to heating - to maintain the temperatures you've programmed. It does
this automatically.
Smart Recovery
The Smart Recovery feature transitions your home from one temperature period
(wake, day, evening, sleep) to the next so that the your home's temperature
matches the temperature setting at the start of each time period. This means, for
example, that if your sleep period temperature setting is lower than the period
that precedes it, the thermostat will start cooling down the home before the
beginning of the scheduled sleep period. It does this at an energy-efficient rate.
This not only helps make your home as comfortable as possible, it also makes
your thermostat more cost effective. Call your dealer to adjust Smart Recovery
settings.
