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-SM1404UT-E with RAV-SM2804AT8-E)

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

(Ex. Combination of RAV-SM1402BT-E and RAV-SM2804AT8-E: Outdoor unit only is 4 series.)
