10.1. INDOOR UNIT (EXCEPT RPK)

10.1.1. INPUT AND OUTPUT SETTING OF INDOOR
PCB CONNECTOR
For the external input and output signal, there are two input
ports (CN3) and three output ports (CN7, CN8) prepared on
the indoor unit PCB.
In case of changing the setting (factory-set) perform the
following procedures using PC-P1HE Remote Control.
§
Field Setting Mode
Check to ensure that the unit is stopped, press the
"CHECK" switch and the "RESET" switch on the remote
control switch simultaneously more than 3 seconds, and
the remote control switch is changed to the field setting
mode. When the remote control switch is at the field
setting mode, the "SERVICE" is indicated and the "01"
flickers below the "SERVICE" indication.
§
Input and Output Setting Mode
At the field setting mode as described in the above item,
press the "TEMP ~ " switch or the "TEMP }" switch and
the number flickering below the "SERVICE" indication is
changed (01 <=> 02).
Set the flickering number at "02", leave this condition for
7 seconds or press the "CHECK" switch, and the remote
control switch is changed to the mode for input or output
setting of Indoor Unit.
§
Selection of Indoor Unit
a. At the input and output setting mode, the indication on
the remote control switch is changed as shown in the
figure below.
É
The indication of "02" is turned ON
Ê
The address of the indoor unit which the optional
function is to be set, is indicated at the segments
for timer setting time indication, and the "ADDS" is
indicated below.
Ë
The refrigerant cycle number of the indoor unit for
the input and output setting is indicated at the
segments for timer setting time indication, and the
"RN" is indicated below.
Ì
The indication of the setting temperature is turned
OFF.
b. At the condition of the above item (a), press the
"TEMP ~" switch or the "TEMP }" switch of the remote
control switch and the indoor unit for the input and output
setting can be changed.
?
NOTE:
The indoor unit can be selected among the indoor
units connected to the remote control switch.
In case that both indications of the address and the
refrigerant cycle number is "AA", all the indoor units
connected to the remote control switch are selected. in
this case, the individual setting for each indoor unit
can not be performed.
c. After selecting the indoor unit, leave the condition for 7
seconds or press the "CHECK" switch, the remote control
switch is changed to the input and output setting mode.
§
Setting Procedures
a. At the input and output setting mode, the indication on
the remote control switch is changed as shown below.
É
The allocated port for input and output signal is
indicated at the segments for timer setting time
indication.
Refer to the indicated port and the connector of the
indoor PCB for the table below.
Ê
The codes of the input and output signals are
indicated at the segments for setting temperature
indication.
Refer to the indicated code and the input and output
