Wiring Diagrams

Indoor Units 13

4.1 Some connectors introduce:

A For remote control (ON-OFF) terminal port CN23 and short connector of JR6

1. Remove the short connector of JR6 when you use ON-OFF function;

2. When remote switch off (OPEN), the unit would be off;

3. When remote switch on (CLOSE), the unit would be on;

4. When close/open the remote switch, the unit would be responded the demand within 2

seconds;

5. When the remote switch on. You can use remote controller/wire controller to select the mode

what you want; when the remote switch off, the unit would not respond the demand from remote

controller/wire controller.

When the remote switch off, but the remote controller/wire controller are on, CP code would be

shown on the display board.

6. The voltage of the port is 12V DC, design Max. current is 5mA.

B For ALARM terminal port CN33

1. Provide the terminal port to connect ALARM, but no voltage of the terminal port , the power

from the ALARM system (not from the unit )

2. Although design voltage can support higher voltage, but we strongly ask you connect the

power less than 24V, current less than 0.5A

3. When the unit occurs the problem, the relay would be closed, then ALARM works

Wiring Diagrams

Indoor Units 14

C. For new fresh motor terminal port CN8

1. Connect the fan motor to the port, no need care L/N of the motor;

2. The output voltage is the power supply;

3. The fresh motor cannot excess 200W or 1A, follow the smaller one;

4. The new fresh motor will be worked when the indoor fan motor work ;when the indoor fan

motor stops, the new fresh motor would be stopped;

5. When the unit enter force cooling mode or capacity testing mode, the fresh motor isn’t work.

C.Micro-switch SW3 is for selection of auto-restart function.

Range: Active, inactive

D. Micro-switch SW5 is for setting the master or slave unit when the unit is in twin connection.

Range: Master no slave (Normal 1 drive 1 connection), Master (2 positions without difference),

Slave

E.Micro-switch SW6 is for selection of temperature compensation in heating mode. This helps

to reduce the real temperature difference between ceiling and floor so that the unit could run

properly. If the height of installation is lower, smaller value could be chosen.

G. Dial-switch ENC1: The indoor PCB is universal designed for whole series units from 18K to

55K. This ENC1 setting will tell the main program what size the unit is.

NOTE: Usually there is glue on it because the switch position cannot be changed at random

unless you want to use this PCB as a spare part to use in another unit. Then you have to select

the right position to match the size of the unit.
