2. Indoor Unit Control PCB Switches and Functions
2-3. Explanation of Functions (CR-UXRP71B-B*)
* Some models of the type U use CB-UXRP71B-B instead of CR-UXRP71B-B.
T10
(CN061)
(for remote control operation)
6P plug (YEL):
Used for remote control operation.
Control items:
Start/stop input
Remote controller prohibit input
Start signal output
Alarm signal output.
Wiring example : Refer to 2-4. T10 Terminal Wiring Example
• No Signal OFF
z
EXCT
(CN073)
2P plug (RED): Can be used for demand control. When input is present, forces the unit to
operate with the thermostat OFF..
Wiring example :
* Lead wire with 2P plug (Special-order parts: WIRE K 623 174 4263)
EXCT
Relay (Field supply)
Relay coil signal
Indoor unit control PCB
(2P plug [RED])
Note: The wire length from the indoor unit control PCB to the relay must be within 2 meters.
z
DISP
(CN072)
(CN063)
2P plug (WHT)/Short-circuiting this plug allows the indoor unit to operate independently.
(Mainly used at the shop front and exhibitions etc. Please do not connect to the outdoor
unit.)
CHK
(CN071)
(CN062)
2P plug (WHT)/Test pin. Short circuiting this pin allows the indoor fan motor (High) to be
checked. However, this function stops when the indoor unit safety device is activated. The
components will operate even if the remote controller and outdoor unit are not connected,
but the remote controller 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.
Default status: Pulse signal
Jumper wire cut: Static signal (continuous signal)
FAN DRIVE
(CN032)
2P plug (WHT)/This terminal sends a signal to the ventilation fan when a commercially
available ventilation fan is operated by the FAN button on the wired remote controller. Use a
ventilation fan which can accept the no-voltage contact A signal as the external input signal..
Wiring example :
Lead wire with 2P plug (Special-order parts: WIRE K 623 162 4435)
FAN DRIVE
Relay (DC 12V field supply)
DC 12V
Indoor unit control PCB
(2P plug
[WHT])
To external-control input
terminal on ventilation fan
Note: The wire length from the indoor unit control PCB to the relay must be within 2 meters.
