Toshiba RAV-SM / RAV-SP aircon error codes

How to check Toshiba RAV-SM / RAV-SP aircon error code?

Toshiba error codes are displayed directly on wired remote controller – to access the service history:

  1. Press the TEST and the SET button of the remote controller for at least 4 seconds.
  2. Scroll through stored codes using the TEMP set buttons.
  3. Then, press the TEST button again to cancel service history.
  4. The final step is press the CLEAR button to delete codes

A note: Up to 4 Codes can be stored.

Toshiba RAS “N” Series aircon error codes

How to check Toshiba RAS “N” Series aircon error code?

Fault codes are displayed through the LEDs flashing at 5 times per second. Note, the green LED will flash once per
second when the system is initially powered.

More specific codes may be obtained, while in the fault mode through the wireless controller.

  1. Press CHK to enter service mode
  2. Navigate through TIMER buttons until all LEDs flash, accompanied by the internal buzzer – compare the
    displayed code with the table below
  3. Press CLR button to clear the existing fault code (controller displays 7F).
  4. Press ON/OFF button to exit service mode.

Important: Do Not turn off the power supply before reading the fault codes, doing so will clear the diagnostic memory.

Caution: must be taken when removing the access covers as high voltages are present.

RAS – Auto Restart Function

The indoor unit is equipped with an automatic restart facility that allows the unit to restart, at the last set operating conditions, after a power failure. The operation will resume without warning three minutes after power is restored. This feature is not set up when these systems are shipped from the factory, therefore it will need to be activated by the installing company.

Generally the process is the same for all RAS products since approx 2001 and is as follows:

To initiate auto restart:

  1. Turn the power on. Green On/Off light will flash.
  2. Set the system to operate using the remote controller. Green On/Off light will be on constantly.
  3. Press and hold down the temporary button for three seconds.
  4. The indoor unit will bleep three times to acknowledge set up. In most cases the green light changes to orange.
  5. The system will continue to operate during this set up.
  6. After set up the system may be stopped using the remote controller.

To cancel auto restart:

  1. The system is operating. Green On/Off light will be on constantly.
  2. Stop the system operating using the remote controller. Green On/Off light will extinguish.
  3. Press and hold down the temporary button for three seconds.
  4. The indoor unit will bleep three times to acknowledge cancellation.
  5. The system will have stopped operating.

This feature cannot be set if the timer is in operation. The louver will not swing, if it was previously set, when the system auto restarts.
