Interface

Each Settings Sub screen consists of a setpoints list and the current value. The operator selects a setpoint to change by touching either the description or setpoint value. Doing this causes the screen to switch to the Analog Settings Subscreen shown below.

Analog Settings Subscreen 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 buttons. Analog setpoints are displayed as spin buttons. The lower half of the screen is reserved for help screens. To change the setpoint the ENTER key must be touched, otherwise the new setting is cancelled.
