UI performs "showroom animation":
• All five LEDs (RC & FC TEMP LEDs) turn on one by one from
left to right and then right to left and keep cycling. (Cycling
rate: 1 cycle per second).
• Showroom mode does not activate sleep mode.
• If there is no user action during 2 minutes of showroom
mode, the animation will stop and then UI behaves (fake) as
normal mode.
• During the animation, if the user touches any key, the
animation will stop and UI behaves as a fake normal mode.
• During fake normal mode, after two minutes without user
interaction, the animation will start again to indicate that UI
is in showroom mode.
Fake normal mode is normal
mode with all cooling loads
off.
Press (FC TEMP SETTING or RC TEMP
SETTING) key in the showroom
mode.
The recommended temperature setting (i.e. <colder>) is on.
Then UI behaves (fake) as normal mode if the user presses any
key again, except that cooling stays off in showroom mode and
no temperature setting is saved.
Press (LIGHT) Key in show room Behavior will be same as normal operation.
Press (ICE TYPE) key in show room
mode.
