Error mode detected by outdoor unit

The check code has been ramified from the indoor unit of 6 series and after.

The ramified check code is displayed only when the indoor unit is 6 series and after and the outdoor unit is 4 series. (Ex. Combination of RAV-SM1406BT-E with RAV-SP1404AT-E)

When the outdoor unit is 3 series and before, the conventional check code is displayed. (Ex. Combination of RAV-SM1406BT-E and RAV-SM1403AT-E: Indoor unit is 6 series.)
