2 Safety
2.1 Intended use
The device must only be operated within the specified technical data!
Extensive functions are available for the control elements. The scope of applications is
contained in chapter "Application ... " (only in languages of the countries EN and CN).
The integrated bus coupler makes possible the connection to a KNX bus line.
Note: They may only be installed in dry interior rooms in flush-mounted sockets
according to BS 4662:2006+A1:2009.
2.2 Improper use
The control element represents a danger if it is improperly used. Each non-intended use
is deemed improper use. The manufacturer is not liable for damages resulting from such
improper use. The associated risk is borne by the user/operator.
The control element must never be use outdoors or in bathroom areas. Do not push
objects through the openings in the control element. The control element has an
integrated bus coupler. The use of an additional bus coupler is therefore not admissible.
2.3 Target groups and qualifications
Installation, commissioning and maintenance of the product must only be carried out by
trained and properly qualified electrical installers. The electrical installers must have read
and understood the manual and follow the instructions provided. The operator must
adhere to the valid national regulations in his country governing the installation, functional
test, repair and maintenance of electrical products.
2.4 Liability and warranty
Improper use, non-observance of this manual, the use of inadequately qualified personnel,
as well as unauthorized modification excludes the liability of the manufacturer for the
damages caused. It voids the warranty of the manufacturer.

7 Installation and electrical connection
Warning
Electric voltage!
Risk of death due to electrical voltage of 230 V during short-
circuit in the low-voltage line.
– Low-voltage and 230 V lines must not be installed together in
a flush-mounted socket!
7.1 Requirements for the electricians
Warning
Electric voltage!
Install the control element only if you have the necessary
electrical engineering knowledge and experience.
• Incorrect installation endangers your life and that of the user
of the electrical system.
• Incorrect installation can cause serious damage to property,
e.g. due to fire.
The minimum necessary expert knowledge and requirements
for the installation are as follows:
• Apply the "five safety rules" (DIN VDE 0105, EN 50110):
1. Disconnect from power;
2. Secure against being re-connected;
3. Ensure there is no voltage;
4. Connect to earth and short-circuit;
5. Cover or barricade adjacent live parts.
• Use suitable personal protective clothing.
• Use only suitable tools and measuring devices.
• Check the supply network type (TN system, IT system, TT
system) to secure the following power supply conditions (classic
connection to ground, protective earthing, necessary additional
measures, etc.).

7.2 Mounting
7.2.1 Installation consideration
The 1/2 gang, 2/4 gang, 3/6 gang, 4/8 gang, Room Temperature Controller, Room
Temperature Controller with 2/4gang control elements are surface mounted device (AP)
with an integrated bus coupler. The control element with RTC function operates with
additional supply voltage. It can be installed on flush-mounted sockets (UP) (China, and
BS).
Selection of a suitable installation location for the controller and suitable parameter
settings are essential for good temperature and proximity detection.
- The room temperature
controller should be
installed approximately
150 cm above the floor
and 50 cm from the door
frame.
- The room temperature
controller should be
installed on a wall opposite
the radiator.
- The radiator and the room
temperature controller must
not be separated by corners
in the room.

KNX Technical Reference Manual
ABB i-Bus®KNX Yucus
15
- The room temperature
controller should not be
installed near a radiator
or behind curtains.
- The room temperature
controller should also not be
installed on an exterior
wall - low outside temperatures
will influence the temperature
regulation.
- The room temperature
controller must not be
exposed to direct contact
with liquids.
- Temperature regulation
will also be affected by
exposure to heat from
electrical appliances and
direct sunlight on the
ambient temperature
controller.

7.2.2 Installation of the control element
1. Install the supporting metal plate onto the flush-mounted box (“TOP” toward the top)
and screw it on to secure.
2. ○
1Install KNX connectors onto the pins at the back of the control element. ○ 2Insert the
control element aiming at the rectangular hole of the supporting metal plate and push
at the front of the control element in until it flush with the surface of the wall. The metal
clip (a) and anti-theft clip (b) secure and limit the movement of the control element in
all direction.

control element
4. To remove the control element, use finger to pull the control element out from side
and create an opening between the control element and the wall. Hold onto the three
sides near the upper area of the control element and pull outward until it was removed
out from the supporting metal plate.

5. To remove control element, install with security clip, a removal tools (come together
with the security clip) will be required. Use finger to pull the control element out from
side and create an opening between the control element and the wall. Hold onto the
three sides near the upper area of the control element and pull outward until it stops
to display the security clip. Insert the removal tools into the side of the control element
as per diagram. Once removal tools are in place, control element would be able to be
remove out from the supporting metal plate.

7.3 Electrical connection
7.4 Maximum number of Yucus devices per TP line
All Yucus range assortment (non RTC and RTC version) maximum power
consumption from the KNX TP line is 20mA per device. Therefore, every individual
installation will require system installers to calculate the total number of KNX power
consumption require by the TP line and install the suitable types of KNX power supply
according to support the KNX TP line.
