Toshiba RAV-SM804BT-TR, RAV-SM454MUT-E, RAV-SM404MUT-TR Error mode detected by outdoor unit, 49

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-SM1404BT-E with RAV-SP1404AT-E)

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

(Ex. Combination of RAV-SM1404BT-E and RAV-SM1403AT-E: Indoor unit only is 4 series.)
