i've done it before using an lcd but I'm not sure if the same works or not when you dont have an lcd connected or displaying the temp
Use a Red/Green bicolor LED, or maybe continuously flash an led on the output, have it output a series of pulses relating to the actual temperature.
If you've got an o'scope, you could output a pulse corresponding to the temp (i.e. 50C = 50ms pulse).
