Wiring Diagrams
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
Indoor Units 13
Wiring Diagrams
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.
Range: 6oC, 4oC, 2oC, E function (reserved for special customizing)
F.Micro-switch S1 and dial-switch S2 are for address setting when you want to control this unit
by a central controller.
Range: 00-63
Indoor Units 16
Wiring Diagrams
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.

Features
1. Features
1.1 Higher Static Pressure
As a ducted air conditioner with medium static pressure, it has the widest static pressure range.
The maximum static pressure reaches 160 Pa
1.2 Slim Design
The industry lowest height is designed to be fitted into tight roof spaces.
*18K unit - 210mm,24K/36K unit - 249mm，48K unit -300mm
1.3 Constant air volume control
For ordinary duct, when the static pressure exceeds the expected range, it is fairly difficult even for an
experienced installer to calculate and adjust the air volume precisely.
With constant air volume control technology, the duct will automatically adjusts to perfect static pressure
and keep constant air volume.
1.4 Flexible Air Intake Way (Bottom side or Rear side)
The frame size of air inlet in rear and bottom is the same. It’s very easy to switch to match different
application.
Indoor Units 27
Features
Air intake from rear (Standard)
Air intake from bottom (Optional)
1.5 Communication wire connection
MUCR-H8 uses two wires without polarity connection way, which almost has no mistake during the
installation.
1.6 Easy Clean
With a larger window design, once the motor and the blower wheels have been detached, heat
exchanger and water receiver tray in behind can be seen very clearly. Dust can be easily removed from
the inside by vacuum
