The temperature in my home is always either too hot or too cold so I suspect the
programmable thermostat is not set correctly.

The owner's manual mentions "set point" but it's not clear what that means.

Is the "setpoint" the temperature at which the furnace (or air conditioner) turns on or turns off?

The set point is the temperature you want the room to be, i.e. when the system turns off.
