The subject will participate in both the Experimental and the Control Admissions. The order of the two admissions will be randomized. During the Control Admission at home, the subject will use the study insulin pump along with a continuous glucose monitor receiver. During the Experimental Admission, the subject will be the research house/hotel where the subject will be in control of the DiAs. Participation in this study will require 5 study visits over 11-14 weeks.
