Abstract: A system and method a wireless remote control solution is implemented in an integrated circuit (IC) and that IC is specified to the controller manufacturer. The controller manufacturer provides an IC-compatible electromechanical interface in communication with a central processing unit (CPU) of the controller. When the manufacturer is ready to implement a wireless solution, the IC is installed into the IC-compatible electromechanical interface. Different wireless solutions and/or protocols are enabled by the manufacturer's choice of IC that is installed.

Abstract: Hardware for converting a door panel into a sliding door includes a pair of two-wheel trolley assemblies for supporting a door panel, a one piece track for attachment above a door opening, and a guide assembly for the bottom of the door panel for stabilizing the door when it is in the closed position. The track has running surfaces at 90.degree. to each other on which the wheels run. For use with doors for refrigerated rooms, one of the running surfaces has elevated portions for raising one wheel of each trolley. When on the elevated portions, the door panel is moved outwards from the door opening, thereby minimizing damage by the sliding panel to the door seals.
