Introduction Welcome to the MINICHEF 2000™ The MINICHEF 2000 is a configurable, time/temperature and machine function controller that is preprogrammed for dozens of cooking applications. Its compact size and optional horizontal/vertical orientation facilitates streamlined equipment design. It withstands rigorous application environment conditions, with an 80ºC ambient rating and superior EMI/RFI immunity. It is also backed by Watlow’s exclusive three-year warranty.
MINICHEF™ 2000 Application Software Selection Table To select the application software that best suits your equipment and purpose, first locate the type of equipment in the left column, then check the other columns for features and options you need. The application number is on the right (Appl#). Make a note of the application number. You will be using this number later when programming your controller.
Overview of Key Steps, from Installation through Operation: 1 Install the controller • 2 • 3 Use the panel knock-out pattern guidelines in this guide. Wire the controller Use the connector/wiring information in this guide. Configure the controller • After applying power, use the Configuration Mode to enter the equipment Application Number (from the MINICHEF 2000 Software Selection table), set up the controller and access the thermal optimization functions.
