Checking the Indoor Unit Addresses
 This is done using the remote controller.
 If a remote controller is connected to each indoor unit, the address is displayed at the remote controller as the “unit num-
ber”.
If a remote controller is not connected to each indoor unit, follow the procedure below and use the remote controller to
operate each indoor unit, one at a time, in fan mode to check the address of each.
<Checking addresses by operating units in fan mode>
(1) Press the
button and the timer time
button simultaneously. (Press and hold for at least 4 seconds.) This switches
the remote controller to address-change mode.
(2) Select the outdoor unit refrigerant system (outdoor unit address).
Use the UNIT button and the FLAP button to select the refrigerant system, then press the SET button to conrm it.
(UNIT = UP button FLAP = DOWN button)
(3) Check the indoor unit address.
When the SET button is pressed in step (2), the indoor unit corresponding to the address displayed (ashing) on the
remote controller begins operating in fan mode.
Find and check the indoor unit that is operating.
