SELECTING AN INSTALLATION LOCATION

4 .1. Dimensions and Name of parts
Remote controller unit(a) Touch screen
(b) Ambient light sensor (inside)
(c) Operation lamp
(d) Room temperature sensor (inside)
This product is manufactured to metric units and tolerances. United States customary units are provided for reference only.
In cases where exact dimensions and tolerances are required, always refer to metric units.
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 significant.
The detection location of the room temperature can be selected from the following 2 methods. Choose the detection location thatis best for the installation location. The temperature sensor of the indoor unit orthe remote controller can be used to detect the room temperature. When the temperature sensor of remote controller is not used, the following functions cannot be used.

•  [Custom Auto] of the operation modes: Refer to operation manual.
• [Away Setting]: Refer to operation manual.
• [Optimum start]: Refer to operation manual.

4.3. Installation space

• Do not embed this remote controller in a wall.
• 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 figure. When there is insufficient space, there may be remote controller sensor misdetections and remote controller removal may be difficult.

(a) Secure enough space where a flat-blade screwdriver, etc. to take off a case can be inserted.

INSTALLING THE REMOTE CONTROLLER

WARNING
Always use the accessories and specified installation work parts. Check the state of the installation parts. Not using the specified parts will cause units to fall off, water leakage, electric shock, fire, etc.
Install at a place that can withstand the weight of the unit and install firmly 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, shut off the equipment to which this unit is connected. Do not supply power until installation work is completed.
Otherwise, it will cause electric shock or fire.
Use the accessories or specified connection cables. Do not modify connection cables other than those specified, do not use extension cords, and do not use independent branch wiring. The allowable current will be exceeded and cause electric shock or fire.
WARNING
Install the remote controller cables securely to the terminal block. Confirm that external force is not applied to the cable. Use remote controller cables made of the specified wire. If intermediate connection or insertion fixing are imperfect, it will cause electric shock, fire, etc.
When connecting the remote controller cable, route the cables so that the rear case of this unit is securely fixed. If the rear case is imperfectly fixed, it may cause fire or overheating of the terminals.
Always fasten the outside covering of the connection cable with the cable tie. If the insulator is chafed, electric discharge may occur.
CAUTION
Before opening the case of this unit, completely discharge static electricity charged on you body. Not doing so will cause trouble.
Do not touch the circuit board and circuit board parts directly with your hands. Otherwise, injury or electric shock could result.
Be careful so that the front case does not fall after the front case screws are removed. Otherwise, injury could result.
Install the remote controller cables 1 m away from television and radio to avoid distorted images and noise.
Confirm the name of each terminal block of the unit and connect the wiring in accordance with the directions given in the manual. Improper wiring work will damage the electric parts and cause smoke and fire.
Connect the connectors securely. Loose connectors will cause trouble, heating, fire, or electric shock.
Never bundle the remote controller cables , the power supply cable and transmission cable together. Bundling these cables together will cause miss operation.
When installing the connection cable near a source of electromagnetic waves, use shielded cable. Otherwise, a breakdown or malfunction could result.
