Is the "cool setpoint" the temperature when the air-conditioner goes
on?
Is the "heat setpoint" the temperature when the heater goes on?

Should the "cool setpoint" temperature be higher than the "heat
setpoint" temperature?

It is actually the temperature they go off as the set temperature is met. I
know what you mean though, one is for winter heating, the other for summer
cooling.

Most thermostats have to be moved from heat to cool so if that is the case,
the actual set temperature does not matter. If yours is fully automatic,
then yes, the heat is below the cooling number In some industrial
applications it is possible to run both heat and AC at the same time to get
humidity control.
