received the signal.) (When wireless remote controller is used, only the Header unit receives SWING signal.
If the SWING signal is transmitted to follower unit, the sound to refuse receiving signal (3 beeps) is heard and
the follower unit does not receive the signal.
For FIX operation, both Header and follower unit perform the operation by itself.
When wired remote controller is used, airflow direction can be changed on each unit by selecting the indoor
unit.)

When the timer is set with wired remote controller, even the TIMER lamp on the Header unit will not light up.
