Remote controller
1. Display range on remote controller
The setup range (Operation mode/Air volume select/Setup temp) of the indoor unit which was set to the header
unit is reflected on the remote controller.
1) Concealed duct high static pressure type (RAV-SMXXX) is not set up on the header unit.
• If the Concealed duct high static pressure type is the header unit:
Operation mode: [Cooling/Heating AUTO] [HEAT] [COOL] [FAN] and no [DRY]
Air volume select: [HIGH]
• When the operation mode is [DRY], [FAN] stops in concealed duct high static pressure models.
2. Address setup
If there is no serial communication between indoor and outdoor when the power is turned on, it is judged as
follower unit of the twin. (Every time when the power is turned on)
• The judgment of header (wired) / follower (simple) of twin is carried out every time. It is not stored in non-
volatile memory.
Turn on power of the indoor unit to be controlled in a group within 3 minutes after setting of automatic address.
If power of the indoor unit is not turned on within 3 minutes (completion of automatic address setting), the system
is rebooted and the automatic address setting will be judged again.
1) Connect indoor/outdoor connecting wire surely.
2) Check line address/indoor address/group address of the unit one by one.
Especially in case of twin, triple, double twin, check whether they are identical system address or not.
3) The unit No. (line/indoor gout address) which have been set once keep the present status as a rule if the unit
No. is not duplicated with one of another unit.
