CAUTION
When indoor unit is used in group control.
1. ECO-Timer and Hi POWER operation will not function.
When Hi POWER or ECO is transmitted from wireless remote control, the receiving sound will be heard from
the indoor unit and display on the remote control will also change. (see page 27.) However, the indoor unit
does not operate ECO-Timer or Hi POWER. (When ECO-Timer is transmitted, ordinary OFF-TIMER
operation is performed.) Restore the display on the remote control pushing Hi POWER or ECO-Timer
button.
2. Units other than the Header unit cannot be operated with remote control and the TEMPORARY
button.
When the air conditioner is operated with wireless remote control, transmission should be sent to the Header
unit.
Header and follower indoor units are decided through address setting upon installation. Follower unit will not
receive any signals from remote control.
Air conditioner will not work even if the TEMPORARY button on the follower unit is pushed.
(Some Follower units may receive SWING and FIX, but these operations are performed only on the unit that
received the signal.)
(When wireless remote control 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, air flow direction can be changed on each unit by selecting the indoor
unit.)

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