Examples of wiring
Note: The length of the wiring from the indoor unit control PCB to the relay must be 2 m or
less.

Examples of wiring
6P plug (yellow): Used for remote control.
FAN DRIVE
(CN017)
2P plug (red): Can be used for demand control. When input is present, forces the unit to
operate with the thermostat OFF.
* Lead wire with 2P plug (special-order part: WIRE K/854 05280 75300)
2P plug (white): Short-circuiting this plug allows the unit to be operated by the remote
controller, even if it is not connected to an outdoor unit. (In this case, alarm "E04," which
indicates trouble in the serial communication between the indoor and outdoor unit, does not
occur.)
2P plug (white): Test pin. Short circuiting this plug allows the operation of the indoor fan
motor (high) and flap motor (F1 position) to be checked.
However this test operation stops if the indoor unit protection mechanism is activated. The
unit can be operated even if the remote controller and outdoor unit are not connected.
However even if the remote controller cannot is connected, it cannot be used to operate the
unit. This function can be used for short-term tests.
Jumper wire: Allows selection of the T10 terminal start/stop signal.
Status at shipment: Pulse signal
Jumper wire cut: Static signal (continuous signal)
2P plug (white): This terminal sends a signal to the ventilation fan when the FAN button on
the wired remote controller is used to operate a commercially-available ventilation fan.
Use a ventilation fan that can accept no-voltage A contact as the external input signal.
* Lead wire with 2P plug (special-order part: WIRE K/854 05280 50600)
