Showroom Mode
Diagnostic code 01 is an optional means of entering or
exiting showroom mode. Default factory settings are
loaded upon entry and normal light and control functions
will be enabled. However, the cooling system will remain
OFF, so the compressors, fans, and dampers will not
function in this mode. Door alarm feature and control
Lock will be same as in normal operating mode. If the
cooling system off set point is selected while in this mode,
SHO

a power failure the unit will restore to showroom mode
upon the return of power. Press and hold the

for 5 seconds to exit showroom mode.
