5.2 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.

Specifications
Page 13 
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

Specifications
Page 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 can not 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 mo
tor 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 .

5.3 Micro-Switch introduce:
A. Micro-switch SW1 is for selection of indoor fan stop temperature (TEL0) when it is in anti-cold
wind action in heating mode.
Range: 24oC, 15oC, 8oC, According to EEROM setting (reserved for special customizing).
B.Micro-switch SW2 is for selection of indoor FAN ACTION if room temperature reaches the setponit
and the compressor stops.
Range: OFF (anti-cold wind is available in heating mode), Keep running (No anti-cold wind function).

H. Dial-switch ENC1: The indoor PCB is universal designed for whole series units from 7K to 68K. 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.
“20” means 2kW (7K),“105” means 10.5kW(36K), and so on.
