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

I tried to Google this feature and Emerson says its designed to adjust
the programmed set point temperature during high demand use of a central
air conditioner. *I think they mean that the thermostat will call on the
variable speed fan/ECM fan will blow faster to similate cooler air,
without the compressor running all the time, but that's just my guess

I can't really get any more information other than that.

I've only had this blower unit/furnace and thermostat for 4 months so no
history with it. *Today was first day using the aircond this year
however A coil and compressor unit are 14 years old, and were run on a
different thermostat the past 13 summers.

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

No idea but I doubt it's going to increase the blower speed to
simulate cooler air during high demand. First I don't think that
would get you anywhere
because whatever speed the blower runs at in all the
homes I've been involved with you never feel any
real breeze or air movement. So it's hard to imagine
you're going to please customers by fooling with
fan speed when it's hot to save what? A couple bucks?
A ceiling fan, that's a different story because it blows
directly on you And I'd bet that 14 year old AC is a
single stage. In which case, again in all the cases
I've seen the furnace blower then runs at the highest
speed when cooling.

Some newer furnaces/AC have features to run the AC
on low for humidity control, but that doesn't appear to
be what they are talking about. Most likely it's what we
call marketing BS. The fact that there is no explanation
probably tells you something.
