5.4.4 Operation
5.4.4.1 Test run
Preparation
• Ensure to perform the test running of air conditioner before turning ON the power supply of the centralised 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 centralised 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 centralised 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 con-
nection check of all 16 groups is completed before the refrigerant cycle address 16, the lighting state is back to the be-
ginning; “Operation Lamp (LED) of Group 1: ON”.
* When all the operation lamp (LED) ickers quickly (cycle: 0.25sec. ON/0.25sec. OFF), the setting of H-LINK adaptive /
non-adaptive is incorrect. Check for the setting of the centralised ON/OFF controller and other centralised controller used
together.
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 actual 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 centralised 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 centralised 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 centralised ON/OFF controller.
