Adjustment of Termination Resistor (Plug)
Communication error will occur if improper adjustment is made.
• When connecting the centralized control system, it is necessary to adjust the termination resistor (terminal plug: CN67).
Even if no connection is made, confirmation is required for VRF systems.
• Termination resistor is placed on the outdoor unit control PCB.
• Centralized control system: Intelligent Controller (CZ-256ESMC2)
System Controller (CZ-64ESMC2)
Schedule Timer (CZ-ESWC2)
ON/OFF Controller (CZ-ANC2)
P-AIMS Basic software (CZ-CSWKC2)
• If the termination resistor of this inter-outdoor unit control wiring is 1 refrigerant system, short-circuit 1 location (remains
unchanged at shipment).
If there are more than 2 refrigerant systems, short-circuit 2 locations (remains unchanged at shipment).
In order to stabilize communication, 2 short circuit locations shall be at both sides (remains unchanged at shipment).
Open-circuit the refrigerant systems except for 2 locations mentioned above.
More than 3 short circuit locations of the termination resistors are prohibited (remains unchanged at shipment).
• There is no necessary to adjust the termination resistor (short circuit remained at shipment) because VRF systems for
combination of sub outdoor units are not connected to the control wiring.
If link wiring is not used
Short-circuit 1 termination resistor plug of the unit No.1 main outdoor unit (remains unchanged at shipment).

Final Check
Be sure to check before operation.
Final check must be done under the conditions of inter-outdoor unit control wiring
connected to the centralized control system and the resistor between conductors
must be measured by a Megger. Check if it is showing between 30Ω and 120Ω.
If the resistance value is out of range, check adjustment of the termination resistor again.
Even if it is out of range, the problem is caused by wiring.
• Is the wiring connection properly completed?
• Are there any scratches or deterioration on the coverage?
Measure between conductors and also between wiring and ground by 500V Megger
insulation resistance tester. Make sure the Megger is showing more than 100MΩ.
When measuring, remove both ends of the wiring from the terminal board.
If not removed, it will be damaged. If it is less than 100MΩ, a new wiring connection
should be made.
