Quick Reference Guide
To assist service engineers working on Toshiba air conditioning equipment, there is a large quantity of
data available via the new “Lite Vision – plus” remote controller the RBC-AMS51E-ES, this data is NOT
available via an Infra-Red remote or the RBC-AS21E2 simplified remote controller.
Accessing the data is a simple process of entering into the on-board menu of the remote controller.

Fault Code Guide
Current fault codes are displayed automatically at the top of
the LCD display, (Warning symbol, Code: *** along with the
affected unit no.)
Main power switch flashes “Green”.
Fault code history can be accessed by accessing the “Field
Setting Menu”
1) Press the ”“button to
display the menu screen
2) Press and hold the” “button
and the” “button at the same time
for more than 4 seconds to display the
“Field setting menu”
3) Scroll down to item “3” using the
button.
4) Press “F2”
A list of the latest 10 alarm codes along with date, time and unit are displayed.
The oldest data are deleted in order to record the newest, the date and time when the error occured for
the first time are displayed for any repeated alarms.
Refer to the Technical Handbook for fault code diagnosis and descriptions
Code: *** Unit 1 - 1
!

To erase the fault code history.
1) Press the “ [F2]” button whilst
the list of alarm codes is displayed.
2) When the display has changed press
the “ [F1]” button.

Data Retrieval Guide
There are two levels for system data, the first level is the monitor mode, which shows basic temperatures
indoor and outdoor, filter time and system running hours.
To access this data press the
1) Display’s the set temperature.
2) Display’s the temperature measured by the TA return air sensor
within the indoor unit. If the system is programmed to use the room
sensor in the remote controller this will be displayed replacing the TA
data.
3) Display’s the temperature measured by the TO ambient air sensor
within the outdoor unit.
4) Display’s the remaining time until the filter sign is displayed.
5) Display’s the accumulated operating time of the system.
To access the second level of data display.
5) Press the button to
display the “Menu screen”
6) Press and hold the”“button
