2-22-3.Checking indoor unit addresses
Use the remote controller to check the addresses of the indoor units. Press and hold
the
button and button for 4 seconds or longer (simple settings mode, “ALL”
appears on the remote controller).
Then press the
button and select the indoor address.
(For the system addresses of the No. 1 outdoor unit, each time the button is pressed,
the address changes as follows: 1-1, 1-2, ...)
The indoor unit fan operates only at the selected indoor unit.
Confirm the indoor unit address. (For the system addresses of the No. 2 outdoor unit,
the displayed addresses are 2-1, 2-2, ...)
Press the
button again to return to the normal remote controller mode.
2-22-4.Indicating (marking) the indoor and outdoor unit combination number
Indicate (mark) the number after automatic address setting is completed.
(1) So that the combination of each indoor unit can be easily checked when multiple units are installed, ensure
that the indoor and outdoor unit numbers correspond to the system address number on the outdoor unit control
PCB, and use a magic marker or similar means which cannot be easily removed to indicate the numbers in an
easily visible location on the indoor units (near the indoor unit nameplates).
Example: (Outdoor) 1 – (Indoor) 1, 2...
(Outdoor) 2 – (Indoor) 1, 2...
(2) These numbers will be needed for maintenance. Be sure to indicate them.
K Type (for Link Wiring)
2-23. Caution
• This unit may be used in a single-type refrigerant system where 1 outdoor unit is connected to 1 indoor
unit, and also in a system where 1 outdoor unit is connected to multiple indoor units (maximum 4).
• If link wiring is used, set the outdoor unit system address to allow the combination of indoor and outdoor units to
be identified. At the same time, indicate the indoor-outdoor unit combination number in a location where it can
be checked easily (near the indoor unit nameplates). (This number will be required for subsequent maintenance.
Refer to 2-26-3, -4.)
• Request that the customer be present when the test run is performed.
At this time, explain the operation manual and have the customer perform
the actual steps.
• Be sure to pass the manuals and warranty certificate to the customer.
• Check that the 220 – 240 V AC wiring is not connected to the inter-
unit control wiring connector terminal. If 220 – 240 V AC is accidentally
applied, the indoor or outdoor unit control PCB fuse (0.5 A for both
indoor and outdoor units) will blow in order to protect the PCB. Correct
the wiring connections, then disconnect the 2P connectors (indoor: blue,
OC) (outdoor: blue, serial 1) that are connected to the PCB, and replace
them with 2P connectors (indoor: brown, EMG) (outdoor: brown, serial 2).
If operation is still not possible after changing the brown connectors, try
cutting the varistor (black) (both indoor and outdoor).
(Be sure to turn the power OFF before performing this work.)
