Error mode detected by outdoor unit

The indoor unit check code has been ramified from 4 series and after.

The ramified check code is displayed only when combined with 4-series indoor unit. (Ex. Combination of RAV-SM1404UT-E with RAV-SM1403AT-E1)

When the indoor unit is 3 series and before, the conventional check code is displayed. (Ex. Combination of RAV-SM1402CT-E and RAV-SM1403AT-E1)
