Outdoor Unit Power Jumper Connector Connection
There are limitations on the total number of units that are connectable to each refrigerant system. Refer to the DATABOOK
for details.
*1 The need for a power supply unit for transmission lines depends on the system configuration. Some controllers, such as
GB-50ADA, have a function to supply power to the transmission lines.
*2 The replacement of the power jumper connector from CN41 to CN40 must be performed on only one outdoor unit in the
system.

Outdoor Unit Centralized Controller Switch Setting
*1 Set SW5-1 on all outdoor units in the same refrigerant circuit to the same setting.
*2 When only the LM adapter is connected, leave SW5-1 to OFF (as it is).

Room Temperature Detection Position Selection
To stop the fan during heating Thermo-OFF (SW1-7 and 1-8 on the indoor units to be set to ON), use the built-in thermistor
on the remote controller or an optional thermistor.
1) To use the built-in sensor on the remote controller, set the SW1-1 to ON.
(Factory setting: SW1-1 set to "OFF".)
Some models of remote controllers are not equipped with a built-in temperature sensor.
Use the built-in temperature sensor on the indoor unit instead.
When using the built-in sensor on the remote controller, install the remote controller where room temperature can be detected.
(Note) Factory setting for SW1-1 on the indoor unit of the All-Fresh Models is ON.
2) When an optional temperature sensor is used, set SW1-1 to OFF, and set SW3-8 to ON.
When using an optional temperature sensor, install it where room temperature can be detected.
