Remote Control, Wiring and functions
①
Install remote control referring to the attached manual.
②
Wiring of remote control should use 0.3mm
2
x2 cores wires or cables.
The insulation thickness is 1mm or more. (on-site configuration)
③
Maximum 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
2
. Change the wire size outside of the case
according to wire connecting. Waterproof treatment is necessary at the wire connecting section. Be careful about
contact failure.

Installation and wiring of remote control
Control plural indoor units by a single remote control
A maximum of two remote control units can be connected to one indoor unit (or one group of
indoor units.)
Latest "function setting" is superior than previous one.
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.
