It shows 32007210-001 Rev. A and Honeywell Inc., Minneapolis, Minnesota 55422. The number 0544 is stamped on the box. The unit's own nameplate is not shown, so voltage, contact ratings and serial number are not listed.

The unit is packed in a brown cardboard box with the Honeywell label on the end. The box shows scuffs, creasing and dirt from storage, and the edges on one side are torn, exposing the gray inner board.
