WARNING
CAUTION
Please entrust the distributor or professionals to install the unit.
Strictly follow this manual.
Reinstallation must be performed by professionals.
Do not disassemble your air conditioner at will.
Do not install the unit in a place vulnerable to leakage of ammable gases.
The wiring should adapt to the wire controller current.
The specied cables shall be applied in the wiring. No external force may
be applied to the terminal.
Do not place the wired remote controller near the lamps, to avoid the remote
signal of the controller to be disturbed. (refer to the right gure)

2. Prepare the following assemblies on the site.
Note to installation of GW-KNX(A) - (K05-KNX 01 A):
1. One KNX module can only connect with one indoor unit;The KNX module should
connecttoindoorD1D2Eports.
2.CircuitofGW-KNX(A)-(K05-KNX01A)islowvoltagecircuit.Neverconnect

TheIntroductionGW-KNX
Simpleinstallation.
GreatexibilityofintegrationintoyourKNXprojects.
Allows the use of a KNX temperature sensor for the air conditioning control.
GW-KNX allows monitoring and control, fully bi-directionally, of all the functioning
parameters of Midea Air Conditioners from KNX installations.
Can be installed inside the own indoor unit, it connects directly in one side to the
electronic circuit of the indoor unit (cable supplied) and in the other side to the KNX
TP-1(EIB)bus.
