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.

*1. Do not shut off power to the outdoor units. Doing so will cut off the power supply to the compressors and the heater on
the outdoor units and may result in compressor malfunction when operation is restored after a power failure.
*2. Not applicable to units with a built-in drain pump or humidifier.
*3. Models with a built-in drain pump cannot be turned on/off by the plug individually. All the units in the same refrigerant cir-
cuits will be turned on or off by the plug.
*4. Requires that the dipswitch settings for all the units in the group be made.
*5. To control the external input to and output from the air conditioners with the PLC software for general equipment via the
AE-200, set SW1-9 and SW1-10 to ON. With these settings made, the power start-stop function becomes disabled. To
use the auto recovery function after power failure while these settings are made, set SW1-5 to ON.
