Characteristics
- Wall controllers with low-upstroke control WSB3-20 and WSB-20H are the main and most
frequently used units (controller) in the iNELS system.
- Built-in micro-buttons with low upstroke off er elegant and easy control.
- Wall switches WSB3-20 and WSB3-20H are available in two-channel version.
- Double color (red/green) LED diode indicates either status of controlled appliances or status of
any sensor or actuator in the system.
- Wall buttons in WSB3 series are compatible with both types of frames LOGUS
90
(85.6 x 85.6 or 94
x 94 mm), therefore you can combine them with double and triple frames and classic products
of the series.
- Each controller is equipped with a temperature sensor. It is also equipped with two analog/
digital inputs (AIN/DIN), which can be used to connect two potentialless contacts or one external
temperature sensor TC/TZ (e.g. for measuring fl oor temperature).
- Wall button WSB3-20H is comparable to the WSB3-20 but additionally equipped with a relative
humidity meter and for improved access of air to the sensor is possible to use in place of the
housing cover 99601T 99621T, including accessories 99622 (Vista MT) and 99623 (Vista IRMT).
- Compared to standard wall buttons WSB3-20 and WSB3-20H are more fl exible and multifunctional.
You can for example controll appliances by short and long push of the button (e.g.: dimming,
shutter control, scenes).
- Each button can control any appliance in the system and can use a variety of centralized or
time controlled features. Accordingly, the customer can choose the simplicity / complexity of the
operation. The big advantage is the possibility to change the method of control by only making
software modifi cations without physical interventions into the structure of the building.
- Each button (fold) can have diff erent functional modes beside lighting control:
a) Classic wall switch:
- upper button ON, bottom button OFF.
b) Button controller (impulse relay):
- fi rst press ON, second press OFF.
c) Dimmer:
- short press - ON/OFF; long press - setting intensity
d) Time switch:
- ON after press, automatically OFF after set time.
e) Setting light scenes - for example: for watching TV:
- shutters down
- main light 30 % intensity
- wall lamps 50 % intensity.
- WSB3 in LOGUS
90
design is designed for mounting into an installation box.

CONNECTION TO THE SYSTEM, INSTALLATION BUS
iNELS3 peripheral units are connected to the system through the BUS installation. Installation BUS
conductors are connected to the terminal units to BUS+ and BUS- terminals, wires cannot be interchanged.
For installation of BUS it is necessary to use a cable with a twisted pair of wires with a diameter of at least
0.8 mm, the recommended cable is iNELS BUS Cable, whose features best meet the requirements of the
BUS installation. Bearing in mind that in terms of all the properties is it is possible in most cases also use the
cable JYSTY 1x2x0.8 or JYSTY 2x2x0.8, however it is not recommended as the best option. In the case of a
cable with two pairs of twisted wires it is not possible to use the second pair of the other for modulated
signal due to the speed of communications; it is not possible within one cable to use one pair for one
segment BUS and the second pair for the second segment BUS. For installation of BUS it is vital to ensure
that it is kept at a distance from the power lines of at least 30 cm and must be installed in accordance with
its mechanical properties. To increase mechanical resistance of cables we recommend installation into
a conduit of suitable diameter. BUS topology installation is free except for the ring, wherein each end of
the bus must terminate at the terminals BUS + and BUS- peripheral unit. While maintaining all the above
requirements, the maximum length of one segment of the installation BUS can reach up to 500 m. Due
to the data communication and supply of units in one pair of wires, it is necessary to keep in mind the
diameter of wires with regards to voltage loss on the lead and the maximum current drawn. The maximum
length of the BUS applies provided that they comply with the tolerance of the supply voltage.
CAPACITY AND CENTRAL UNIT
It is possible to connect to the central unit CU3-01M or CU3-02M two independent BUSes by means
of terminals BUS1+, BUS1- and BUS2+, BUS2-. It is possible to connect to each BUS up to 32 units, so it
is possible to connect directly to the central unit a total of 64 units. It is necessary to comply with the
requirement of a maximum load of one BUS line - maximum up to 1000 mA current. When connecting
units which draw greater than 1A, BPS3-01M with 3A sampling can be used. It is the sum of the rated
currents of the units connected to the BUS line, other units can be connected using the units MI3-02M,
which generate further BUSes. These are connected to the CU3 unit via the system BUS EBM and you can
connect a total of 8 units via EBM BUS to the central unit MI3-02M.
SUPPLYING THE SYSTEM
For supplying power to system units, it is recommended to use the power source of ELKO EP titled PS3-
100/iNELS. We recommend backing up the system with backup batteries connected to the source of
PS3-100/iNELS (see sample diagram of connecting the control system).
GENERAL INFORMATION
To operate the unit, it is necessary that the unit is connected to a central unit CU3 series, connected to the
central unit of the system CU3, or to a system that already contains this unit as its expansion to include
further system.
All unit parameters are set through the central unit CU3-01M in the software iDM3.
There is LED diode on the PCB for indication of supply voltage and communication with the central unit
series CU3. In case that the RUN diode fl ashes at regular intervals, so there is standard communication
between the unit and BUS. If the RUN diode lights permanently, so the unit is supplied from BUS, but there
is no communication between BUS and unit. In case that RUN diode is OFF, so there is no supply voltage
on the terminals BUS+ and BUS-.
