slabat, I checked and only have on and off. I did pull the cover off and there is a slide on the top left. This slide was pushed up on the screw, I moved it off the screw and it seems to work as intended now. I don't know specifically where that slide should be but the heater worked perfectly throughout the night. Thanks for all the help, to everyone, I appreciate it.
