8-3. Error Mode Judgment by LED Display of Outdoor Unit
There provided Dip switch (SW801) and LED on the “Application Control Kit” (TCB-PCOS1E) sold separately for
SM56 and SM80 models, and on the outdoor unit P.C. board for SM110 and SM140 models respectively.
The status of the outdoor unit at that time can be known by switching this Dip switch. The lighting status of LED
also notifies the judged stage before the outdoor error has been determined and displayed on the remote
controller. An error of the outdoor temp. sensor (TO) may be confirmed only by LED display according to the
indoor unit to be combined.
