opti idle thermostat question

I finally got 1st seat and my own truck. They saddled me with a 2008 freightliner century with the opti idle. I figured out howto turn it on. But I am the kind of person that likes to know how everything works. I have a digital thermostat in the sleeper and have been messing with it. I tried finding a manual online but had no luck. Can someone explain exactly how I use it or point me in the right direction for a manual?

Actually your link did help. I traced it back to here http://www.freightlinertrucks.com/parts-service/service/manuals.aspx and found online manuals. Hopefully what I need will be there.

EDIT: ok got it all figured out. Now my only problem is when the truck starts itself my power inverter gets a power surge and shuts itself off, emitting a very annoying beep that wont quit iun the process.
