I have an Emerson thermostat that claims to have a feature called cool
savings...


Anyone care to explain what this feature is and how it works? Emerson
"Cool Savings"

Maybe it runs the indoor fan for 1-2 mins after the compressor shuts
down, to blow all the cool air in the evaporator into the living spaces.

From the thermostat's manual:

"With Cool Savings enabled, the thermostat will make small adjustments
to the setpoint temperature during periods of high demand to reduce
AC system running time and save energy. When the cooling system has
been running for more than 20 minutes, humidity in the home will be
lower and a higher temperature will feel comfortable. After 20
minutes of run time, the thermostat will start increasing the setpoint
temperature in steps of less than one degree as the system continues
to run. These adjustments will eventually cause the system to satisfy
the thermostat to turn the system off and reduce the energy
consumption. When the Cool Savings feature is active and making
adjustments, the display will flash 'Cool Savings'. The amount of the
adjustments to the setpoint temperature is dependent on the Cool
Savings value that is set, 1
being the least adjustment and 6 being the most adjustment . With this
feature set to OFF, no change will occur when the AC system is
continuously running during the periods of high demand. Periods of
high demand will normally occur during the late afternoon and early
evening on the hottest days of the summer . As demand lessens the
adjustments to setpoint temperature are reversed
until setpoint temperature returns to normal and 'CoolSavings' no
longer flashes."

In short: when you activate the Cool Savings option, after the a/c has
been running for at least 20 minutes it will gradually raise the
thermostat's temperature setting, which will shut off the a/c. You
choose whether to use the option, and you choose how drastic of a
temperature rise you are prepared to tolerate to save on energy.
