HOT KEY F FOR DIXELL XR20C CONTROLLER

Controls of all kinds are integral parts of restaurant equipment operation. A control is a switch or other device by which a machine is regulated. A control may be manual or automatically operated. An electro-mechanical control typically consists of multiple relays, timers, and/or counters wired together on an enclosure panel. Electro-mechanical control is also referred to simply as "Relay Control", which is a more accurate term since solid state electronic relays, timers, and counters are standard components. Contactors, motor and compressor starters, valves, thermostats, and other output devices are used to turn on/off motors, indicator lights, heating elements, and other components used in the equipment.

A key is a small, shaped metal implement for operating a switch in the form of a lock. A key may similarly be a pin, bolt, or wedge inserted between other pieces, or fitting into a hole or space designed for it, so as to lock parts together. It may have incisions cut to fit the wards of a particular lock, which is inserted into a lock and turned to open or close it.
