Setpoint Screen

The setpoint screen is a two-part screen. Screen 1 lists all
setpoints available to change along with their current
value. The operator selects a setpoint to change by
touching either the verbal description or setpoint value.
Doing this causes the screen to switch to Screen 2.
In Screen 1 the language setpoint will always be the last
setpoint in the list. This will facilitate language changes by
placing that control in a standard position across all
CH.530 product lines.
Screen 2 displays the current value of the chosen setpoint
in the upper ½ of the display. It is displayed in a
changeable format consistent with its type. Binary
setpoints are considered to be simple two state
enumeration and will use radio buttons. Analog setpoints
are displayed as spin buttons. The lower half of the screen
is reserved for help screens.
