ELECTRICAL WIRING
13.3.3. H-LINK SYSTEM
1. Application:
The new H-LINK wiring system requires only two transmission
wires connecting each indoor unit and outdoor unit for up to
16 refrigerant cycles, and connecting wires for all indoor units
and all outdoor units in series.
NOTE:
The H-LINK system can not be applied to the cycle with the
old model unit or the unit with old transmission
This H-LINK system can be applied to the following models.
Indoor Unit
Outdoor Unit
RCI-OOOFSN1E
RCD-OOOFSNE
RPC-OOOFSNE
RPI-OOOFSN1E
RPK-OOOFSNM/FSN1M
RPF-OOOFSNE
RPFI-OOOFSNE
RASC-OOOHNE
2. Features:
The H-LINK has the following features and specifications:
Features:
The tota
l
wiring length is remarkably reduced.
Only one connection is required for the wiring between the
indoor unit and outdoor unit.
Easy wiring connection to the central controllers
Specifications:
Transmission Wire: 2-Wire
Polarity of Transmission Wire: Non-Polar Wire
Maximum Outdoor Units To Be Connected: 16 Units per
H-LINK system.
Maximum Indoor Units To Be Connected: 16 Units per
cycle and 64 Units per H-LINK system
Maximum Wiring Length: Total 1000m (including CS-NET)
Recommended Cable: Twist Pair Cable with Shield, over
0.75 mm2 (Equivalent to KPEV-S)
Voltage: DC5V
3. System Example of H-LINK:
Using H-LINK System For Only Air Conditioners:
There are two typical cases of using H-LINK system;
(1) Using H-LINK System For Only Air Conditioners, and
(2) Using H-LINK System For Air Conditioners With Central
Control Device, and the system examples are as shown

In case that H-LINK is not applied when electrical wiring is
performed
NOTE:
Do not make a wiring in a loop.
In the case that H-LINK is not applied after the when
electrical wiring is performed as shown above, H-LINK is
applied after the instrument wiring is completed. Therefore,
the dip switches are required to be set according to “Setting
of Dip Switches on PCB”.
4. Dip Switch Setting of Indoor PCB and Outdoor
PCB.
It is required to set dip switches of every indoor unit and
outdoor unit.
