It is necessary to perform “group settings” and “paired settings” at making group settings of different refrigerant
systems (multiple outdoor unit).
(A) Group settings: Enter the indoor unit controlled by the remote controller, check the content of entries, and clear
entries, etc.
(B) Paired settings: Used to set the linked operation of a Lossnay unit.
(1) Entering address: Follow the steps below to enter the addresses of the indoor unit using the remote controller.
a) Group settings
Turning off the remote controller: Press the ON/OFF button to stop operation (the indicator light will go off).
Changing to indoor unit address display mode: If the FILTER and
k
buttons on the remote controller are
pressed simultaneously and held for 2 seconds, the display shown in Figure 1 will appear.
Changing address: Press the temperature adjustment buttons to change the displayed address to the
address to be entered.
Entering the displayed address: Press the TEST RUN button to enter the indoor unit with the displayed address.
The type of the unit will be displayed as shown in Figure 2 if entry is completed normally.
If a selected indoor unit does not exist, an error signal will be displayed as shown in Figure 3. When this happens,
check whether the indoor unit actually exists and performs entry again.
Returning to the normal mode after completing entry: Press the FILTER and
k
buttons simultaneously and
hold for 2 seconds to return to the normal mode.
b) Paired Settings
• Turn off the remote controller: Press the remote controller’s ON/OFF button to turn it off (the indicator light will go off).

The above steps are the same as a) Group settings.
• Changing to the linked operation unit address display state: The display shown in Figure 4 will appear when the
a
button on the remote controller is pressed.
• Displaying the address of the Lossnay unit and linked indoor unit: In this situation, the indoor unit
number will be the lowest address of the group. The Lossnay unit will not operate if this setting is
incorrect.

If the temperature adjustment buttons are pressed, the address may be changed to the indoor units that are
to be linked.
*
If the time setting buttons are pressed, the address of the linked units may be changed to the address where
it is desired to enter the Lossnay .
• Linking the Lossnay and the indoor unit: The display shown in Figure 5 will appear when the TEST RUN
button is pressed. The indoor unit whose address is displayed and the Lossnay unit with a linked address
will operate in a linked manner.
*
If it is desired to display the address of the Lossnay in the indoor unit address, display the indoor
unit address in the linked unit address, and the above content will also be recorded.

Apart from the indoor unit with the lowest address in the group, display and enter the addresses of the other indoor unit
that are to be linked with the Lossnay unit.
• Returning to the normal mode after completing entry: Press the FILTER and
k
buttons on the remote controller
simultaneously and hold for 2 seconds to return to the normal mode.
