Default Value Remark
When there are master and slave
wired controllers and the
temperature sensor of wired
controller is used, only the
temperature sensor of the master
wired controller is used by default.
Note:
1) In automatic mode, the
03 environment temperature sensor
settings are invalid for a common
IDU but the setting value is
memorized.
2)The environment temperature
sensor settings are invalid for a
fresh-air IDU. The temperature
sensor of air return vent is used by
default.
