A refrigeration system or a control system for a refrigeration system has a display that by default displays the temperature of a simulated product stored in the refrigeration system as sensed by a temperature probe. The system control logic determines the temperature limits for cutting the refrigeration cycle in or out based on a temperature set-point entered by a user.

Refrigeration system and control system therefor

Refrigeration device

An ice making, and delivery apparatus for making and delivering ice to different ones of a plurality of receptacle units is provided, in which ice delivered via a conduit to a diverter valve mechanism, is diverted from alignment with one ice discharge line to another, depending upon sensors in ice receptacles recognizing a level of build-up of ice in any given receptacle, for computer control of a gearmotor for moving the diverter valve from one position to another. Various controls are provided for preventing ice build-up, and for operating the diverter valve during a 'dwell' period of ice movement in the conduit, as distinguished from a 'push' period of ice movement in the conduit to the diverter valve. A force multiplication technique is employed for moving the diverter valve notwithstanding the presence of ice therein.
