THERMOSTAT USER INTERFACE
The thermostat 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. To turn on the back light to high level, press any key on the front panel. The back lit display
will return to low level when the thermostat is left unattended for 45 seconds
When left unattended, the thermostat has an auto scrolling display that shows the actual status of the system. Use the
MenuScro
in the configuration menu to lockout the scrolling display and to only present the room temperature and
conditional outdoor temperature to the user. With this option enabled, no local status is given on the system mode or
occupancy.
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. When left unattended for 10 seconds after changes are made, the display will resume automatic
status display scrolling.
