CAUTION
● Do not install the remote control at following places.
(1) It could cause break-down or deformation of remote control.
・Where it is exposed to direct sunlight
・Where the ambient temperature becomes 0 °C or below, or 40 °C or above
・Where the surface is not at
・Where the strength of installation area is insufcient
(2) Moisture may be attached to internal parts of the remote controller, resulting in a display failure.
・Place with high humidity where condensation occurs on the remote controller
・Where the remote controller gets wet
(3) Accurate room temperature may not be detected using the temperature sensor of the remote controller.
・Where the average room temperature cannot be detected
・Place near the equipment to generate heat
・Place affected by outside air in opening/closing the door
・Place exposed to direct sunlight or wind from air conditioner
・Where the difference between wall and room temperature is large
● To connect to a personal computer via USB, use the dedicated software.
Do not connect other USB devices and the remote controller at the same time.
It could cause malfunction or break-down of the remote controller/personal computer.

To remove the upper case from the bottom cases of R/C
· Insert the tip of at head screwdriver or the like in the recess at the lower part of
R/C and twist it lightly to remove. It is recommended that the tip of the screwdriver
be wrapped with tape to avoid damaging the case.
Take care to protect the removed upper case from moisture or dust.
In case of embedding wiring
(When the wiring is retrieved “Backward”)
① Embed the switch box and the R/C wires beforehand.
Seal the inlet hole for the R/C wiring with putty.

When taking the wiring out from the upper center, open a hole before separating the upper and bottom cases. This will reduce risk of
damaging the PCB and facilitate subsequent work.
When taking the wiring out from the upper left, take care not to damage the PCB and not to leave any chips of cut thin wall inside.
② When wires are passed through the bottom case, x the bottom case at 2 places on the switch box.

③
Connect wires from X and Y terminals of R/C to X and Y terminals of indoor unit. R/C
wires (X, Y) have no polarity. Fix wires such that the wires will run around the terminal
screws on the top case of R/C.
④ Install the upper case with care not to pinch wires of R/C.
Cautions for wire connection
Use wires of no larger than 0.5 mm2 for wiring
running through the remote control case. Take care
not to pinch the sheath.
Tighten by hand (0.7 N·m or less) the wire
connection.
If the wire is connected using an electric driver, it
may cause failure or deformation.
In case of exposing wiring
(When the wiring is taken out from the “upper center” or “upper left” of R/C)
① Cut out the thin wall sections on the cases for the size of wire.
② Fix the bottom R/C case on a at surface with two wood
screws.
③ In case of the upper center, pass the wiring behind the
bottom case. (Hatched section)
④ Connect wires from X and Y terminals of R/C to X and Y
terminals of indoor unit. R/C wires (X, Y) have no polarity.
Fix wires such that the wires will run around the terminal
screws on the top case of R/C.
⑤ Install the top case with care not to pinch wires of R/C.
⑥ Seal the area cut in ① with putty.

switches together for ve seconds on the administrator password input screen.
○ Service password is “9999”, which cannot be changed.
When the administrator password is input, the service password is also accepted.
Up to two units of R/C can be used
at the maximum for 1 indoor unit or 1
group.
One is main R/C and the other is sub
R/C.
Operating range is different depending
on the main or sub R/C.
