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

Instructing the system to repeatedly cycle between heating and cooling modes to maintain a narrow temperature range would consume A LOT of electricity/fuel as the system would potentially be running nearly constantly.

While on a hot summer day, you really don’t want to run the heater just because the AC ran a little longer than necessary.
