Auto Changeover; Smart Recovery - Carrier Comfort Touch-n-Go Owner's Manual

Auto Changeover
The thermostat displays one of five modes: heat, cool, Em heat (heat pump version
only), heat cool, and off. When the mode selection is for both heating and cooling,
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
(P1, P2, P3, P4) 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.
