4-1341(L) 2(N) U1 U2 R1 R2Indoor Unit7P terminal board4-6. Indoor Unit Control PCB Switches and Functions[Indoor unit control PCB]T10 (CN061): 6P plug (YEL) / Used for remote control operation. (Refer to the Remote Control Section.)Control items: (1) Start/stop input(3) Start signal output(2) Remote controller prohibit input(4) Alarm signal outputEXCT (CN073): 2P plug (RED) / Can be used for demand control. When input is present, forces the unit tooperate with the thermostat OFF.DISP (CN072):(CN063)2P plug (WHT) / Short-circuiting this plug allows operation to be controlled by the remotecontroller even when an outdoor unit is not connected. (In this case, alarm “E04,” whichindicates trouble in the serial communication between the indoor and outdoor unit, does notoccur.)CHK: 2P plug (WHT) / Test pin. Short-circuiting this pin allows the indoor FM (H fan speed), drainpump, flap motor (F1 position), and electronic expansion valve full-open position to bechecked.However this function turns OFF if the indoor unit protection mechanism is activated.The components will operate even if the remote controller and outdoor unit are notconnected, however the remote control cannot be used for control even if it is connected.This plug can be used for short-term tests.JP1 (JP001): Jumper wire / Allows selection of the T10 terminal start/stop signal. (Refer to the RemoteControl Section.)Setting at time of shipment: Pulse signalJumper wire cut: Static signal (continuous signal)Fan drive: 2P plug (WHT) / This terminal sends the signal to the ventilation fan when a commerciallyavailable ventilation fan is operated by the FAN button on the wired remote controller. (Referto the Remote Control Section.)Use a ventilation fan which can accept the no-voltage contact A signal as the external inputsignal.Filter: 2P (WHT) / This terminal is used to connect contact input from the differential-pressureswitch, used to detect filter clogging. When the contact is ON, “FILTER” appears on thedisplay of the wired remote controller.Power LED: LED (RED) / Illuminates when the power is ON. Flashes when there is trouble with theEEPROM (IC10, IC010: nonvolatile memory).EEPROM (IC010): Nonvolatile memory / Used to store model information and other data. When replacingthe PCB, remove the EEPROM from the old PCB and install it onto the new PCB. If there isIC trouble, replace with a new IC (provided with the servicing PCB), and set the necessaryinformation using the wired remote controller. (For the setting procedure, refer to theservicing technical materials.)GRL (CN020): • For AC fan motor (CR-UXRP71B-P) – 3P (YEL)Inter-unitcontrolwiringRemotecontrolwiring7P terminal boardPowersupply
