5. Adjacent Unit Setting Mode

When two indoor units are set adjacently, sometimes,

both indoor units may receive signals from the wireless

remote controller simultaneously. To ensure both indoor

units operate properly, the IR Receiver Kit of one of

them may be set at the mode [adjacent unit setting]. For

example, for two indoor units A and B shown in the right

figure, set B at the mode [adjacent unit setting].

a. Method to set the adjacent unit setting mode

(1) Set the IR Receiver Kit

Set 2nd digit and 3rd digit of the dip switch (DSW1) on the IR Receiver Kit of the indoor device B (object

to be set) to another mode.

(2) Set the wireless remote controller

For setting, please refer to wireless remote controller’s Operation Manual.

b. Method to cancel the adjacent unit setting mode

(1) Set the IR Receiver Kit

The adjacent unit setting mode can be cancelled just by setting 2nd digit and 3rd digit of the dip

switch (DSW1) on the IR Receiver Kit to OFF.

(2) Set the wireless remote controller

For canceling, please refer to wireless remote controller’s Operation Manual.

6. About Simultaneous Control of Multiple Units

One IR Receiver Kit can be used to control simultaneously a number of indoor units (up to 16 devices).

When a number of indoor devices are installed in a large room, one single wireless remote controller can

be used to run and stop all these devices.

NOTE:

When a number of units are under simultaneous control, all their indoor devices shall be placed in the

same room. If using one wireless remote controller to control air conditioners in more than two rooms,

it is possible to forget to close one.

a. Set the IR Receiver Kit

In case of simultaneous operation of multiple (up to 16) indoor units by the wireless remote controller,

install the IR Receiver Kit only to the unit to be operated. Other units should be the standard units

without the IR Receiver Kit. If multiple IR Receiver Kits are required to install, 2 IR Receiver Kits are

available at a maximum.

b. Methods for wire connection and setting for the purpose of simultaneous control of multiple units

(1) Method to connect wires between indoor unit

Perform the connection work as following gure.

(2) The signal cable of all units shall not be in parallel with the power cable within the device and shall

be xed with wire buckle at key places. The distance between the signal cable and the power cable

shall be at least 30 mm outside the devices. Or, put the signal cable through the protective sleeve,

one end of which shall be grounded. When a shielded signal cable is used, one end of the shielding

net shall be grounded.

(3) Set addresses of all indoor devices.

7. Method for Test Running with the Wireless Remote Controller

Please test it in accordance with the wireless remote controller’s Operation Manual.

8. Alarm Code Indication

•

In case that some trouble occurs because of activation of safety device, etc., “ ” (red lamp) ashes

(0.5

second ON / 0.5 second OFF).

• Refer to the Technical Catalogue of airCore 700 unit about Alarm Code List.

• Alarm Code indicates the ashing times of “ ” (green lamp) and “ ” (yellow lamp) as shown below.

“ ” (green lamp): The flashing is shown at the 2 digit of Alarm Code

“ ” (yellow lamp): The flashing is shown at the 1 digit of Alarm Code

(Alphabet Code: A=10 times, B=11 times, C=12 times, .....)

" " (green lamp)

" " flashes 3 times (0.5 second ON / 0.5 second OFF)

" " (yellow lamp) flashes 5 times (0.5 second ON / 0.5 second OFF)

• “” (red lamp) ashing (1 second ON / 1 second OFF) indicates abnormal transmitting between Indoor

Units and Outdoor Unit.
