I still don't really know what I'm doing.

Opti Idle is on and working. I understand how to do the heater but the cooling controls are something I can't figure out. If I stop the fan, it shuts down and won't start. If I move it one notch, it basically keeps running.

I read that the temp on the blue is 60 to 70 degrees. But either way the truck just keeps running, barely cooling or turning it into a refrigerator.

Am I missing something. I know it won't cool it perfectly but my new rig has one tank and don't want it running too much.
