CONFIGURING AND STATUS DISPLAY INSTRUCTIONS
Status display
The Terminal Equipment Controller features a two-line, eight-character display. There is a
low level backlight level 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 actual status of the system.
Each item is scrolled one by one with the back lighting in low level mode. Pressing any
key will cause the back light to come on to high level.
Manual scroll 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.
