I really need a setpoint temperature for the "smarter" HVAC thermistat I am working on. I think I will just use another 18B20 as my setpoint temp and not worry about the alarms.

You lost me there.
Using another 18B20 as a setpoint, would make it a "Variable point".

If you want to make a thermostat, it's probably easiest to just read the temperature and compare it against the desired "setpoints" in your program.
