NOTE
Please use the round-type terminal with correct specifications to
connect the power cord.
8.4.8 Function of terminals
As shown in the figure below, For For GLACIAR75M and
GLACIAR140M,the uint communication signal wire and the
wired controller signal wire is connected to the terminal block
CN22 at XYE on main board inside the electric control box.
For specific wiring, see chapter 8.4.14
CN22(main board)
Uint communication
As shown in the figure below, For GLACIAR90M and
GLACIAR180M: the uint communication signal wire is
connected to the terminal block XT2 at 5(X), 6(Y) and 7(E),
and the wired controller signal wire is connected at 8(X), 9(Y)
and 10(E) inside the electric control box. For specific wiring,
see chapter 8.4.14
XT2
Uint communication
Fig. 8-18 Wiring of unit communication and
the wired controller communication
For GLACIAR180M , Model A is connected to Model B, Model B is
connected to Model A in the next uint. For specific connection, see
chapter 8.4.14.
When the water pump and auxiliary heater are added externally,
a 3-phase contactor must be used for control. The model of
contactor is subject to the power of water pump and heater
power. The contactor coil is controlled by the main control board.
See the figure below for coil wiring. For specific wiring, see
chapter 8.4.14 .
The user can connect an ac light to monitor the state of
compressor.When the compressor is operating,the light will be
powered on.
The wiring of water pump and pipeline auxiliary heater and ac light
of the state of compressor is as follows.

8.4.9 Wiring of "ON/OFF" weak electric port
The remote function of "ON/OFF" must be set by DIP switch .The
remote function of "ON/OFF" is effective when S1-1 or S5-3 is
chosen ON, at the same time, the wired controller is out of control.
Corresponding parallel connect the "ON/OFF" port of the main
unit's electric control box,then, connect the "ON/OFF" signal
(provide by user) to the "ON/OFF" port of main unit as follows.
The remote function of "ON/OFF" must be DIP switch set.
Wiring method:
GLACIAR75M 8L-B and GLACIAR140M :Shorting the terminal
block CN137 at slave board inside the electric control box to enable
the remote function of "ON/OFF" .
For GLACIAR90M and GLACIAR180M : Shorting the terminal
block XT2 at 15 and 24 inside the electric control box to enable
the remote function of "ON/OFF" .
