We claim the ornamental design for a cover for a transport temperature control unit, as shown and described.
FIG. 1 is a top front perspective view of a cover for a transport temperature control unit embodying the invention.
FIG. 2 is a front view of the cover shown in FIG. 1.
FIG. 3 is a right side view of the cover shown in FIG. 1; and,
FIG. 4 is a left side view of the cover shown in FIG. 1.
The portions of the cover shown in broken lines are included for the purpose of illustrating environment and form no part of the claimed design. The bottom is flat and devoid of surface ornamentation. The rear view of the cover is not visible during normal use and is therefore omitted.
