why do digital thermostats have both heat and cool settings, as opposed to a singular temperature control

Question

(e.g why does 70 degrees on “cool” feel colder than 70 degrees on “heat”)?

Answer 1

Your heater and your AC are two different systems. Only one of them operates at a time. If the system is set to 70 the heater or ac isn’t puting out 70 degree air. It’s puting out air as hot or cold as it can. That air then diffuses through out the house.

The temperature on the thermostat just tells your system when you want it to stop blowing out air.
