sensor settings
for IDU
01: temperature sensor
of air return vent
02: temperature sensor
of wired controller
03: temperature sensor
of air return vent for
cooling, dehumidifying,
and air supply;
temperature sensor of
wired controller for
heating
04: temperature sensor
of wired controller for
cooling, dehumidifying,
and air supply;
temperature sensor of
air return vent for
heating
03
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
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.

Press
“ ” or “ ” to add or reduce
by 1°C.
The temperature sensor of unit and
the temperature sensor of wired
controller share the same corrected
value.
In heating mode, corrected value of
temperature sensor of unit =
corrected value of temperature
sensor of wired controller - 2°C.
