Electrical connection points on the main control board are labeled alphanumerically. These labels correspond with
the alphanumeric summary table, located on the wiring diagram. By referencing the summary table, it is possible to

the main control board, and a copy of a model 700BCI-3 summary table. (See Figures 3-2 & 3-3)
NOTE: All components on the control board are non-replaceable. If a problem with the control board is identified,
the complete control board must be replaced.
NOTE: There is also a small control board in the control panel assembly (Not Shown). All components in the con-
trol panel assembly are non-replaceable. If a problemwith the control panel is identified, the complete control panel
