ELECTRICAL AND CONTROL SETTINGS
8.3 MIRROR OPERATION
When the mirror function is active YUTAKI M operates in slave
mode and works with the input/output processor from the
Remote control box and defines how the system operates when
a Remote control box is connected to a YUTAKI M
The Remote control box constantly sends "Data orders" to the
YUTAKI M according to the settings.
8.4 ELECTRICAL WIRING
8.4.1 Connections on the Terminal board 1 (TB1)
The followings connections on the Terminal board 1 of the
Remote control box are required:
N
L1
~ 230V / 50HZ
8.4.2 Connections on the Terminal board 2 (TB2)
!
C A U T I O N
When installing the Remote control box (ATW-YMM-02) electrical connections for the control of the system must be done on the Terminal board 2 of
the PCB 3 of the Remote control box rather than perform those connections on the PCB2 of the YUTAKI M.
H-Link connection
Specific connection for the H-Link transmission must be done in
both PCB, as it is shown in the figure below:
YUTAKI M
Terminal Board 2
•
The H-LINK wiring system requires only two transmission
cables that connect the indoor unit and the outdoor unit.
•
Use twist pair wires (0.75 mm²) for operation wiring between
outdoor unit and indoor unit. The wiring must consist of
2-core wires (Do not use wire with more than 3 cores).

Remote control box
Terminal Board 2
YUTAKI M receives the "Data orders" and replies with "Data
status".
The transmission of data between YUTAKI M and the Remote
control box is done through H-LINK.
•
Use shielded wires for intermediate wiring to protect the
units from noise interference, with a length of less than 300
m and a size in compliance with local codes.
•
In the event that a conduit tube for field-wiring is not used, fix
rubber bushes to the panel with adhesive.
!
C A U T I O N
Ensure that the transmission wiring is not wrongly connected to any live
part that could be damaged the PCB.
