3 How To Install
1.
Choose a place in which to install the remote controller (switch box).
Be sure to observe the following steps:
(1) Temperature sensors are provided with both the remote controller and the indoor units. When using the
External size
of remote
remote controller temperature sensor, the master remote controller detects the room temperature. Install
controller
the master remote controller in a place where the average room temperature can be detected and which
is not affected by any heat source from direct sunlight or air blown from air conditioning units.
CAUTION The place where (when) the difference between the room temperature and the wall tem-
30 mm
perature is large, the wall temperature that is affected by the temperature of the wall on
which the remote controller is installed is measured. Therefore, the difference between
the room temperature and the measured wall temperature may be large.
When the installation site is one of the followings, use of a temperature sensor for an
indoor unit is recommended.
- When the room is not well-ventilated and the air does not reach the wall on which the
remote controller is installed.
- When the difference between the temperature of the wall on which the remote con-
troller is installed and the room temperature.
- When the backside of the wall on which the remote controller is installed is exposed
to the outdoor air.
When the temperature changes drastically, the temperature may not be measured accu-
rately.
When a remote controller temperature sensor is used in a place which is likely to be affected by the wall on which the remote controller is
installed, use of an optional spacer (Model: PAC-YT83RS) for a remote controller is recommended.
(For how to set the main and sub remote controller, see step (1) "Remote controller" [4]-3. (1) in section
6 Function Selection .
For how to set the temperature sensor, see step (2) "Unit function selection" in section 6 Function Selection .)
(2) When installing on either the switch box or the wall, allow extra space around the remote controller as shown in the figure at the right.
NOTE: Make sure that there is no wiring or wire near the remote controller sensor. If there is, the remote controller cannot detect the exact room
temperature.

To remove the cover, insert a minus
screwdriver into one of the open
slots, and move it in the direction of
the arrow shown in the figure.
First, hook the cover to the two upper claws and then fit it to the remote controller.
CAUTION Press the cover until it snaps shut. If not, it may fall off.
CAUTION Do not into turn the screwdriver in the slot. Doing so may damage the slot.
NOTE: A protection sheet is stuck to the operation section. Peel off this protection sheet before use.
