After fully understanding the following contents (identifiers and icons), read the text body and observe the following rules.

Identifier description

[Note]:
1. “Harm” means injury, burn and electric shock which need long-term treatment but need no hospitalization
2. “Property loss” means loss of properties and materials.

Icon description

icon or by images or characters aside.
| It indicates compulsory implementation. The compulsory subject-matter is indicated in the icon or by  images or characters aside.

WARNING

Please entrust the distributor or professionals to install the unit.
Installation by other persons may lead to imperfect installation, electric shock or fire.
Strictly follow this manual.
Imporper installation may lead to electric shock or fire.
Reinstallation must be performed by professionals.
improper installation may lead to electric shock or fire.
Do not disassemble your air conditioner at will.
A random disassembly may cause abnormal operation or heating, which may result in fire.

CAUTION

Do not install the unit in a place vulnerable to leakage of flammable gases.
Once flammable gases are leaked and left around the wire controller, fire may occure.
The wiring should adapt to the wire controller current.
Otherwise, electric leakage or heating may occur and result in fire.
The specified cables shall be applied in the wiring. No external force may be applied to the terminal.
Otherwise, wire cut and heating may occur and result in fire.
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 figure)

Other precautions

• Installation Location
  Do not install the unit in a place with much oil, steam, sulfide gas. Otherwise, the product may be deformed and failed.

• Preparation before installation
  1. Check whether the following assemblies are complete.

Note to installation of MGW-KNXCS:

1. One KNX module can only connect with one indoor unit;The KNX module should connect to indoor D1D2E ports.
2. Circuit of MGW-KNXCS is low voltage circuit. Never connect it with a standard 220V/380V circuit or put it into a same Wiring Tube with the circuit.
3. Do not attempt to extend the shield cable by cutting, if it is necessary, use Terminal Connection Block to connect.
4. After finishing connection, do not use Megger to have the insulation check to the signal wire.
5. The default physical address of the MGW-KNXCS is 15.15.255,If there are two or more KNX modules, then the physical addresses can not repeat.The physical address can be changed by ETS software.
6. Before installation, need prepare KNX power module .

   ● MGW-KNXCS is completely in conformity with EIB/KNX standard. ETS software must be used by integrator to carry out configuration and project design.
   For detailed information of ETS software, please contact knx association: www.knx.org.
   ● ETS database （.vd）of MGW-KNXCS please consult ActronAir representative.

Wiring installation instruction
The Wiring diagram follows,the MGW-KNXCS connect to the indoor Unit and KNX Power.

The Introduction MGW-KNXCS

• MGW-KNXCS allows monitoring and control, fully bi-directionally, of all the functioning parameters of Air Conditioners from KNX installations.

• Simple installation.
  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.

• Great flexibility of integration into your KNX projects.
  Configuration is made directly from ETS, the database of the device comes with a complete set of communication objects allowing, from a simple and quick integration using the basic objects, to the most advanced integration with monitoring and control all the indoor unit’s parameters. Also available specific device’s communication objects, as for example save and execute scenes.

• Allows the use of a KNX temperature sensor for the air conditioning control.
