TROUBLE SHOOTING
●
When the display is converted to Option Setting mode, the entire display is to be turned off except the
Fridge & Freezer 7-SEG LEDs as follows.
1) The following shows the way to shift the Freezer temperature by -3 (-6 ) This function is to shift its
base temperature. For example, if the current base temperature is -18
(0 ) and it is lowered by
3
(6 ) with the Option Setting function, the unit is to be controlled based on -21 (-6 ) that is
even though it shows -18
(0 ) on the display panel after shifting the base temperature.
2) With the Option Setting mode, "0" blinks on both of the Fridge and the Freezer sections. (Generally,
they are set to "0" at both the Fridge and the Freezer sections. But, they can be changed for the
purpose of quality improvement.) - When "0" blinks on the Fridge section, it is set to the Freezer
Option Setting and the Freezer temp code will be displayed on the Freezer temp section.
3) If the Freezer temp code is set to "6" as the following table after setting the Fridge section to "0", the
Freezer base temperature is to be lowered by 3
(6 ) (Refer to the Freezer temperature setting
image.)
: In 15 seconds(20 seconds for RSG5B* Model) after completing the adjustment, MICOM is to store
the setting value in EEPROM and it goes back to the normal display mode, deactivating the Option
Setting mode.
4) The above Option Setting is the same for both of the Dispenser model and the No-Dispenser model.
5) With the same method as the above, you can control the Fridge and the Cool Select Zone
temperature.
6) Make sure not to change the factory-set default values otherwise exception cases. Also, the Option
Setting is to be completed when it goes back to the normal display mode in 20 seconds. So, do not
turn off the unit before it goes back to the normal display mode.
The units are shipped out with all their data being cleared. i.e. the setting values are "0" for all
together. But, for the purpose of quality improvement, the settings can be changed before
being shipped out, make sure to check relevant SVC bulletins.
NOTE
There are more functions which can be adjusted. But, they are not to be described in this
manual because they are not actually related to the diagnosis of the unit. (Do not change the
option settings other than the ones described in this manual)
