② Remote control, wiring and functions
● Do not install it on the following places
①Places exposed to direct sunlight
②Places near heat devices
③High humidity places
④Hot surface or cold surface enough to generate condensation
⑤Places exposed to oil mist or steam directly.
⑥Uneven surface
Installation and wiring of remote control
①Install remote control referring to the attached installation manual.
②Wiring of remote control should use 0.3mm
The insulation thickness is 1mm or more. (on-site configuration)
③Maximum prolongation of remote control wiring is 600 m.
If the prolongation is over 100m, change to the size below.
But, wiring in the remote control case should be under 0.5mm
outside of the case according to wire connecting. Waterproof treatment is necessary at the
wire connecting section. Be careful about contact failure.
100 - 200m ........................ 0.5mm × 2 cores
2
Under 300m ....................... 0.75mm 2
Under 400m ....................... 1.25mm
2
Under 600m ....................... 2.0mm × 2 cores

④Avoid using multi-core cables to prevent malfunction.
⑤Keep remote control line away from earth (frame or any metal of building).
⑥Make sure to connect remote control line to the remote control and terminal block of indoor
unit. (No polarity)
Control plural indoor units by a single remote control
①A remote control can control plural indoor units (Up to 16).
In above setting, all plural indoor units will operate under same mode and temperature setting.
②Connect all indoor units with 2 core remote control line.
③Set unique remote control communication address from "0" to "F" to each inside unit by the
rotary switch SW2 on the indoor unit's PCB.

Remote control line (no polarity)
Remote control
Master/ slave setting when more than one remote control unit are used
A maximum of two remote control units can be connected to one indoor unit (or one group of
indoor units.)
The air-conditioner operation follows the last operation of the remote control regardless of the
master/slave setting of it.
Acceptable combination is "two (2) wired remote controls", "one (1) wired remote control
and one (1) wireless kit" or "two (2) wireless kits".
Set one to "Master" and the other to "Slave".
Note:The setting "Remote control unit sensor enabled" is only selectable with the master remote
control unit in the position where you want to check room temperature.
