LCD & Keypad
These options are accessible through the LCD and keypad
(see figure below). To become familiar with the options
loaded into a particular unit, scrolling through the SET
and CFG menu will show the descriptions of the options
(see pages 16-17). These menus are the very same menus
that are used to access the setting and/or configuration
of these options. The SET (setting) menu is primarily
used to show or change, time and voltage settings. The
CFG menu is primarily used to turn an option on or off.
When scrolling through these menus, no changes can
be made without entry of the access code. The factory
set six-digit access code is located on a white label on
the back of the unit (see figure 11 pgs. 16-18).
The Entelli-Switch 250 has many logic options. Each
controller is downloaded with options at the time of
manufacture. The collection of options that any one
controller has is specified at the time of order placement.
The following pages include all the options that can reside
in the controller. Not all units include all options.
