ELECTRONIC CONTROL SERVICE INPUT OPERATIONS
Model Configuration Mode
The main control board is used in several different models, so when a 700-3 Base Unit is manufactured, the main
control board must be configured/programmed for the specific model it is used in by a series of key strokes at the
control panel. This is called Model Configuration.
If a new main control board is installed during a service call, double dashes ( - - ) will appear on the LCD (See
Figure 3-55). This indicates the new board must be configured for the model it was installed into. This is accom-
plished in Model Configuration Mode, which is entered as soon as power is supplied to the unit. While in this mode,
open the bottom drawer, then toggle through the model codes by pressing WARMER or COLDER keys, until appro-
priate model code is displayed (See Figure 3-56 and 3-57, and Model Code Table below). With appropriate model
code displayed, press UNIT ON/OFF key to store model configuration (See Figure 3-58).
