Its controlled by the smaller of the rooms btw. Also Riker has the issue of the air only goes up and down by so much despite what the thermastat says. So since they really only drop to 70 its more likely that your just getting the extra chill from the cement blocks they built with retaining the cold/heat. So there isn't much you can do. I know once the heat comes on full swing it blasts and you'll prob have to open the windows in riker to cope with the temp.
But yeah as a riker 1 resident I can say our quad gets toasty as is some nights via the floor so we're already getting heat from pipes and the folks below us.
