I just got my thermostat and the directions scare me. It's a Johnson Controls on/off and I can't figure out how to set it...Can someone give me some plain english step by steps?

Here's the link to it: http://www.mgreptiles.com/johnson1.html

I got it with a power strip attatched to it. So far I plugged the heat lamp into it, should I plug in the heating pad too? How do I set the temps? Does the probe go next to the bulb or in the tank or on the heating pad?

*seizure*
