Yes it is temp control.
You should have a Positive Block in the Middle and 2 Posts on the Sides, These are your Negatives. As long as you have one lead start at a positive and end at a negative then your coil will be fine, the problem occurs if a lead from your opposing coil comes out of the block or post and touches the other coil. This causes a short and can melt your coils or worse. You never mentioned what gauge wire you were using but if your using 26g, you should make atleast 8 wraps and a 2.5mm bit or bigger.
I'm sure that's the problem, how do I keep one side from touching the other coils?You should have a Positive Block in the Middle and 2 Posts on the Sides, These are your Negatives.

You want something very identical to this:
If your nervous about something or unsure about your build, dont be afraid to ask here....Its better to get some information before anything can happen or go wrong!
Put one coil in and use nail clippers or flush cutters and clip the leads that poke out to the other side and bend anything that remains into the hole it came from. When putting in the second coil, just above the positive block hold the coil like it would be when its all done and take a visual measurement of how short the positive lead needs to be cut, then cut it now. Then insert the coil and adjust it, make sure the lead is not poking out the block, if it is remove the coil and clip it shorter.
