I cannot seem to keep my office the right temperature

My husband and I moved halfway across the country about two years ago because he was offered a great position in a new business. I then had to find a new job which I did not look forward to, however thankfully, I found one within a weeks of searching. I have a higher paying job which is nice, however I have to say that many of my coworkers are quite tough to get along with. I left a job filled with friends, and I just do not see myself developing many friendships here. I do have one loyal friend that I am thankful for, however the rest of my coworkers seem to dislike their jobs and their lives. I have had trouble lately with the temperature in my office. I set the control unit just where I want it to be, however it consistently ends up in a odd venue by the end of the afternoon. One of my coworkers told me that he saw another coworker going into my office to put some papers on my desk during my supper break, and he was the only guy who went into my office besides me that entire afternoon. I hated to recommend that he had been messing with my control unit, however I could not come up with any other logical explanation. I did something quite naughty yeahterday and set up a camera in my office so that when I went to supper break I could see what went on. Sure enough, that same coworker as yeahterday dropped some things off in my office and turned my control unit up. I do not understand why, however I am going to have to report him now that I have video evidence.
