INSTALLATION AND OPERATION MANUAL
16
The input function is set by the dip switch (SW19) as follows:
1. Simultaneous Operation/Stoppage
This function is for operating/stopping all the indoor units of the
group, which is set by the centralized ON/OFF controller, by the
external contact signal.
2. Simultaneous Operation
This function is for operating all the indoor units of the group
simultaneously, which is set by the centralized ON/OFF controller, by
the external pulse signal.
3. Simultaneous Stoppage
This function is for stopping all the indoor units of the group
simultaneously, which is set by the centralized ON/OFF controller, by
the external pulse signal.
4. Transmission Function of Emergency Stop Signal
This function is for stopping all the air conditioners connected to
the centralized ON/OFF controller by the external emergency stop
signal.
* When other centralized controller is used together, even in the
state of emergency stop, the RUN/STOP operation by other central
controllers is available.
5. Simultaneous Operation Output
This function is for outputting signal outward in the case where there
is any air conditioner in operation in the group set by the centralized
ON/OFF controller.
7. CHECKING PROCEDURE
7.1. PREPARATION
- Ensure to perform the test running of air conditioner before turning
ON the power supply of the centralized ON/OFF controller.
- Check to ensure that the setting temperature is indicated on the
remote control switch after the test running of air conditioner.
(If the setting temperature is not indicated on the remote control
switch, the test running of the centralized ON/OFF controller is not
available.)
1. Perform the group recognition according to the following procedures.
a. After the operation check of air conditioner, turn ON the power
supply of air conditioner.
b. Turn ON the power supply of the centralized ON/OFF controller
and reset.
c. The operation lamp (LED) turns ON and the connection check
is started. The group recognition is completed when all the
operation lamp turns OFF.
<Flowchart of Operation Lamp (LED) Lighting State>
Operation Lamp (LED) of Group 1: ON
Operation Lamp (LED) of Group 2: ON
Operation Lamp (LED) of Group 3: ON
Operation Lamp (LED) of Group 16: ON
During connection check, the operation lamp (LED) turns ON as
shown above and repeats several times.
When the connection check of all 16 groups is completed before
the refrigerant cycle address 16, the lighting state is back to the
beginning; "Operation Lamp (LED) of Group 1: ON".
* When all the operation lamp (LED) flickers quickly
(cycle: 0.25sec. ON/0.25sec. OFF), the setting of H-LINK
adaptive / non-adaptive is incorrect. Check for the setting of the
centralized ON/OFF controller and other centralized controller
used together.
6. Simultaneous Alarm Output
This function is for outputting signal outward in the case where there
is any air conditioner in abnormal condition in the group set by the
centralized ON/OFF controller.
The input function is set by the dip switch SW19-1 as follows:
Function Setting of SW-19-1
ALL RUN/STOP
(Level)
ALL RUN (Pulse)
ALL STOP (Pulse)
Specifications of Required Components:
Input: Non-Voltage A Connection (DC12V)
Output: DC12V
OMRON MY Relay (Recommended)
PCC-1 Cable (Option): For Connection of External Input/Output

ATTENTTION:
Use the cable more than 0.3mm2 (Field-Supplied, Maximum
Length: 70m) for Input/Output.
2 Check the group.
a. Check to ensure that the group recognition is correct by operating
air conditioner from group 1 in order.
b. When the actural operation corresponds to the group setting, it is
considered that the group recognition is correct.
c. If the actual operation does not correspond to the group setting,
the connection is incorrect. Turn OFF the power supply of the
centralized ON/OFF controller, check for the following items and
correct the wiring connection and the setting.
- Is the power supply turned ON and the wiring connection
correct?
- Is the setting of the indoor unit address and the refrigerant cycle
address correct?
- Is the address setting of the centralized ON/OFF controller
correct?
d. After correcting the wiring connection and the setting, turn ON the
power supply of the indoor unit and the outdoor unit, and reset
the centralized ON/OFF controller.
7.2. RESETTING OF CENTRALIZED ON/OFF
CONTROLLER
1. Depress the switches "15" and "16" simultaneously for 3 seconds
when all group is stopped. The operation lamps (LED) of the group
15 and 16 is turned ON.
2. Depress the switches "15" and "16" simultaneously again. The
operation lamp (LED) of the group 16 flickers, then depress the
switch "2" and confirm that the operation lamp(LED) of the group 6 is
turned ON.
3. When the resetting of centralized ON/OFF controller is completed, all
the operation lamp (LED) is turned OFF, and the group recognition is
started again.

ATTENTTION:
DO NOT perform the resetting within 3 minutes after the operation
order from the centralized ON/OFF controller is performed. If the
resetting is performed within 3 minutes, the remote control switch
may be in the state of centralized control. When turning OFF the
power supply of the centralized ON/OFF controller within 3 min-
utes, the same consequence may occur.
