Did it come with an instruction book?
It should be as simple as setting a temperature, setting it to cooling or heating, and setting an overshoot value. You may also have to choose the input device (thermocouple, thermistor).
While I am not familure with that controller, I have programmed LOVE PID controllers before. Using it as an on-off is pretty easy to set up. Maybe take ya an hour. Good Luck!
