• Twin combination
The combination where 2 indoor units are installed for 1 outdoor unit.
• Group combination
Operate air conditioners in more than one system (such as single combination and twin combination) in same time.
• Header unit
The representative unit during twin and group operation. Receive commands from remote controller and transmit the
commands to follower units.
(The header unit is indoor unit that receives START / STOP signal from the wireless remote controller.)
• Follower unit
Indoor units other than the header unit are called follower unit.
CAUTION
When using indoor unit in group control,
1. Hi POWER operation will not function.
When Hi POWER is transmitted from wireless remote controller the receiving sound will be heard from the indoor unit and display
on the wireless remote controller will also change. However, the indoor unit does not operate Hi POWER operation. Restore the
display on the wireless remote controller pushing Hi POWER button.
2. COMFORT SLEEP
When COMFORT SLEEP is transmitted from wireless remote controller, the receiving sound will be heard from the indoor unit
and the display on the wireless remote controller will also be changed as same as Hi POWER operation. However, the set
temperature and the fan speed will not be automatically adjusted. Only off timer function is activated.
3. Units other than the Header unit cannot be operated with remote controller and the TEMPORARY operation.
When operating air conditioner with wireless remote controller 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 wireless remote controller.
Air conditioner will not work even if the
button on the follower unit is pressed.
(Some Follower units may receive SWING and FIX, but these operations are performed only on the unit that 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.)
4. TIMER lamp lights up only on the Header unit.
When the timer is set with wired remote controller, even the TIMER lamp on the Header unit will not light up.
