Abstract: An ice-making machine with an add on board that has a processor, a log program and a log memory. The log program periodically writes current values of operation parameters of the ice making of the machine in the log memory and makes the logged data available to an external device at predetermined times or when the current values contain an error condition.

Abstract: An ice-making machine having an assembly and a controller that controls said assembly to make ice. A sensing device senses a current level of ice in an ice bin that receives the ice made by the assembly. The controller compares the current level to a high set point and a low set point and, based on a current energy rate, controls the assembly to maintain the current level at or near the high set point when said current energy rate is low and at or near the low set point when the current energy rate is high to provide energy efficiency. The controller and sensing device are part of a retrofit assembly that retrofits an existing ice machine with the energy efficient feature.

Abstract: Ice-making machine with an add on board that has a textual display that can be used for a user to view various parameters of the ice-making machine and its operation and in some cases to adjust the parameters. The add on board includes a processor and a display program that presents a main menu and a series of sub-menus that are selectable from a list on the main menu. The display program includes both a view mode and an adjust mode.

Abstract: An ice-making machine and method that control the ability of an ice-making machine to make ice in response to the occurrence of lockout events, which may be due to part malfunction, power load maintenance, failure to make lease payments and other concerns. Upon the occurrence of a lockout event, a message is sent from a remote site and received by a receiver associated with the ice-making machine. The message includes a lockout command that is transferred to a controller of the ice-making machine. The controller then disables the ice-making machine from making ice.

Abstract: An ice-making machine and method of maintaining and cleaning an ice-making machine are provided. The ice-making machine has predictive maintenance and cleaning. Operational conditions of the ice-making machine, such as, for example, water quality, are used to establish service intervals and/or types of service, and the service intervals and/or types of service are indicated to the user with a lead-time to allow for timely obtaining the service.
