Retrofits or retrofitting is not unusual with foodservice equipment. A retrofit is the addition of new technology or features to older systems. Retrofits include backward compatibility so that the newer component will work in existing equipment. Retrofits allow for menu additions, software updates, and component improvements without the replacement or addition of functional equipment.

A timer is a specialized type of clock used for measuring specific time intervals. Timers can be categorized into two main types. A timer which counts upwards from zero for measuring elapsed time is often called a stopwatch, while a device which counts down from a specified time interval is more usually called a timer. It is a control device that outputs a signal at a preset time after an input signal is received and then triggers another device or action.
