Installation
The device has degree of protection IP20, and is therefore suitable for use in dry interior rooms. The
installation of the device requires the following steps:
a)
fix the metallic support with the screws supplied on a wall box with distance between fixing holes of
60 mm. It is recommended to install the device at a height of 150 cm;
b)
if required, snap a square frame of the form or flank series, inserting it from the rear of the device;
c)
connect the sensors or the contacts required to the 4-poles screw terminal block on the rear of the
device;
d)
insert the terminal for the bus (red/black), previously connected to the bus cable, in its slot on the
rear side. At this point it is recommended to carry out the commissioning of the device or at least the
download of the physical address;
e)
install the device on the metallic support through the spring system, tightening then the two screws
f)
requires also to tighten the screws included in the delivery. For mounting the device follow also the
indication TOP (arrow tip pointing up) on the rear side of the device;.
g)
snap the two rockers onto the device for the operation of the room temperature controller.
The device can only be mounted on a round or square wall flush mounting box with 60 mm distance between
fixing holes. If necessary, the metallic support for mounting on the wall box can also be ordered separately.
2.1
Connection
For the operation the device has to be connected to the bus line and addressed, configured and
commissioned with ETS (Engineering Tool Software). The connection of one or two sensors to the inputs is
optional and must be defined by the planner of the bus system.
2.1.1
Connection of the bus line
The connection of the KNX bus line is made with the terminal block (red/black) included in delivery and
inserted into the slot of the housing.
Characteristics of the KNX terminal block
•
spring clamping of conductors
•
4 seats for conductors for each polarity
•
terminal suitable for KNX bus cable with single-wire conductors and diameter between 0.6 and 0.8
mm
•
recommended wire stripping approx. 5 mm
•
color codification: red = + (positive) bus conductor, black = − (negative) bus conductor
2.1.2
Connection of the inputs
The connection of the inputs is made with the screw terminals located at the rear side of the device. The
maximum cable length is 10 m. For the connection use a cable of max section 1,5 mm². The connection
cable must have sufficient length to allow the extraction of the device from the wall-mounting box.
Characteristics of the terminal blocks for the inputs
•
screw clamping of conductors
•
maximum cross section of conductor 1 mm² (multiwire)
•
recommended wire stripping approx. 5 mm
