Status display
The Room 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 Room 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.
