PCB and Functions

2. Indoor Unit Control PCB

6. Explanation of Functions (CR-KXRP56AN, CR-KXRP80AN, POW-KRP50A)

T10	6P fl ag (yellow): Used for remote control.
(CN105)	Control items:	Start/stop input	Remote controller prohibit input
(for remote control)		Start signal output	Alarm signal output
EXCT	2P plug (red): Can be used for demand control. When input is present, forces the unit to
(CN009)	operate with the thermostat OFF.

zExamples of wiring

*Lead wire with 2P plug (special-order part: WIRE K/854 05280 75300)

Relay (field supply)

EXCT	Relay coil signal
(2P plug (red))

	Indoor unit control PCB
	Note: The length of the wiring from the indoor unit control PCB to the relay must be 6-9/16 ft.
	or less.
DISP	2P plug (white): Short-circuiting this plug allows the unit to be operated by the remote
(CN010)	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.)
CHK	2P plug (white): Test pin. Short circuiting this plug allows the operation of the indoor fan
(CN011)	motor (high) and fl ap 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 be connected, it cannot be used to operate the unit. This function can be used for
	short-term tests.
JP001	Jumper wire: Allows selection of the T10 terminal start/stop signal. Status at shipment: Pulse
	signal. Jumper wire cut: Static signal (continuous signal)
FAN DRIVE	2P plug (white): This terminal sends a signal to the ventilation fan when the FAN button on
(CN017)	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.
