The remote function of “ON/OFF” must be set by DIP switch .The
remote function of “ON/OFF” and “HEAT/COOL” is effective
when S5-4 for
CSAD UiAWP 100 PS
and
CSAD UiAWP 200 PS
or S5-3 for
CSAD UiAWP 300 PS
is chosen ON, at the same
time, the wire controller is out of control.
Corresponding parallel connect the “HEAT/COOL” port of the
main unit’s electric control box,then, connect the “ON/OFF” signal
(provide by user) to the “HEAT/COOL” port of main unit as
follows.
Wiring method: When
CSAD UiAWP 100 PS
and
CSAD UiAWP 200 PS
enable “HEAT/COOL” control, short the
“HEAT/COOL” ports on the main control board.
When
CSAD UiAWP 300 PS
enables “HEAT/COOL” control,
short the terminal block XT2 at 14 and 23 inside the electric
control box.

“ALARM” port
Device provided by user
Connect the device provided by user to the “ALARM” ports of the
module units as follows.
b. The shielding nets at both ends of the shielded wire must be
grounded. Alternatively, the shielding nets of all shielded wires
are interconnected and then connected to earth through or one
`metal plate.
c. Do not bind the control wire, refrigerant piping and power cord
together. When the power cord and control wire are laid parallel,
they should be kept at a distance of more than 300 mm to prevent
signal source interference.
d. Pay attention to the polarity of the control wire when conducting wiring
operations.

If the unit is operating unnormally,the ALARM port is closed,
otherwise,the ALARM port is not closed.
The ALARM ports for
CSAD UiAWP 100 PS
,
CSAD UiAWP 200 PS
and
CSAD UiAWP 300 PS
are on the main
control board. See the wiring
nameplate for details.
8.5.17 Control system and installation precautions
a. Use only shielded wires as control wires. Any other type of wires
may produce a signal interference that will cause the units to
malfunction.
