The basic procedure for setting the temperature is you just press the set key and it toggles between showing you the number of seconds it will be on each cycle (A then the number), or the set temperature. Pressing the up or down keys when in temperature mode allows you to set the temperature. Pressing the right or left arrows allows you to choose which decimal position to move up or down.
As for programming, hold down the set key until it enters the programming mode. Each press of the set key will move it down one option. Options are given in the manual:
As for tuning it, you need to take notes on how it's behaving then make adjustments to the P, I, and D terms to improve the behavior. I can help you with that as well. I've got mine holding to +/- 1/10th of a degree C now.
No problem I can help you program it. How is it working now? Is it overshooting or undershooting? What is the wattage of your heater(s) and what type of container is the water in (plastic box, or picnic cooler)?
Sure I have a couple of new J probes. How does $12 each sound? You can email me the cash and I can mail the probes to you . . . or we can meet in the Byward Market sometime, where I work.
