Showroom Mode
This mode is designed to show units in a display
environment. When in this mode the only functions will be
the control and cabinet lights. The compressor, fans, etc.
will not operate. To enter/exit this mode hold the light key
and the power key for 5 seconds. The display will flash
once and beep and the degree symbol will begin to flash.
When the degree symbol is flashing the unit will allow the
use of the control for demonstrations. The unit can be left
in this mode indefinitely.
