4.2. Setting the room temperature detection
location
CAUTION
As the temperature sensor of remote controller detects the temperature
near the wall, when there is a certain difference between the room
temperature and the wall temperature, the sensor will not detect the
room temperature correctly sometimes. Especially when the outer side
of the wall on which the sensor is positioned is exposed to the open air,
it is recommended to use the temperature sensor of the indoor unit to
detect the room temperature when the indoor and outdoor temperature
difference is signi
fi
cant.
The detection location of the room tempera-
ture can be selected from the following 2
methods. The temperature sensor of the
indoor unit or the remote controller can be
used to detect the room temperature.
Choose the detection location that is best for
the installation location.
A sensor of the indoor
unit (inside)
A sensor of the remote
controller (inside)
If using the remote control sensor, setting is required.
Refer to 6.3.5.
RC (Remote Controller) Sensor Setting.
4.3. Installation space
• Do not embed this remote controller in a wall.
• Recommendation installation height of the remote controller is 1.4 m (55
in) (from the
fl
oor surface to the bottom of the remote controller).
• Even when you install a remote controller to one of a switch box and the
surface of a wall, secure the space shown in following
fi
gure. When there
is insuf
fi
cient space, there may be remote controller sensor misdetec-
tions and remote controller removal may be dif
fi
cult.

INSTALLING THE REMOTE
CONTROLLER
WARNING
Always use the accessories and speci
fi
ed installation work parts. Check
the state of the installation parts. Not using the speci
fi
ed parts will cause
units to fall off, water leakage, electric shock,
fi
re, etc.
Install at a place that can withstand the weight of the unit and install
fi
rmly so that the unit will not topple or fall.
When installing this unit, make sure that there are no children nearby.
Otherwise, injury or electric shock could result.
Before starting installation work, turn off the power of this unit and the
connection destination. Do not turn on the power again until installation
is completed. Otherwise, it will cause electric shock or
fi
re.
Use the accessories or speci
fi
ed connection cables. Do not modify con-
nection cables other than those speci
fi
ed, do not use extension cords,
and do not use independent branch wiring. The allowable current will be
exceeded and cause electric shock or
fi
re.
Install the remote controller cables securely to the terminal block. Con-
fi
rm that external force is not applied to the cable. Use remote controller
cables made of the speci
fi
ed wire. If intermediate connection or inser-
tion
fi
xing are imperfect, it will cause electric shock,
fi
re, etc.
When connecting the remote controller cable, route the cables so that
the rear case of this unit is securely
fi
xed. If the rear case is imperfectly
fi
xed, it may cause
fi
re or overheating of the terminals.
Perform functional earthing work positively. Do not connect the func-
tional earthing wire to a telephone earth (Ground) wire, water pipe, or
conductor rod.
Always fasten the cable sheath of the connection cable with the cable
tie. If the cable sheath is chafed, electric discharge may occur.
