Toshiba RAV-SP404ATZG-E, RAV-SP804ATZG-E, RAV-SP804ATZ-E Error mode detected by outdoor unit

Error mode detected by outdoor unit

The check code has been ramified from “4 series” and after.

The ramified check code is displayed only when both the indoor unit and the outdoor unit are “4 series” and after. (Ex. Combination of RAV-SM804UT-E with RAV-SP804AT-E)

When the indoor unit is 3 series and before, the conventional check code is displayed.

(Ex. Combination of RAV-SM802BT-E and RAV-SP804AT-E: Outdoor unit only is “4 series”.)
