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)

1. One KNX module can only connect with one indoor unit;The KNX module should
connect to indoor XYE ports, can’t connect to outdoor XYE ports.
2. Circuit of CWC 01 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 CWC 01 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.

● CWC 01 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 SYSCONTROL CWC 01 consult our company.
① Bus interface：Power supply DC 29V, 10mA and connect to KNX bus；
② KNX programming button：press once to enter the programming mode,
press it again will exit.
③ KNX programming statues lamp：when it is light up means programming
status and can write data to the module by KNX bus
④ RS485 communication ports：Communication port between KNX module
and indoor unit.

● CWC 01 allows monitoring and control, fully bi-directionally, of all the functioning
parameters of Systemair Air Conditioners from KNX installations.
● Simple installation.
Can be installed inside the own AC indoor unit, it connects directly in one side to
the electronic circuit of the AC 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 AC 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.
