Status display
The Terminal Equipment Controller features a two-line, eight-character display. There is a
low level backlight that is always active and can only be seen at night.
When left unattended, the Terminal Equipment Controller has an auto scrolling display
that shows the current status of the system.
Each item is scrolled sequentially with the back lighting in low level mode. Pressing any
key will cause the back light to come on to high level.
Manual scrolling of each menu item is achieved by pressing the Yes (scroll) key
repetitively. The last item viewed will be shown on the display for 30 seconds before
returning to automatic scrolling. Temperature is automatically updated when scrolling is
held.
Sequence of auto-scroll status display:
