3- INSTALLATION
The controller must be installed in a place protected from vibrations, water and corrosive
gases, and where ambient temperature does not surpass the value specified in the techni-
cal data.
In order for the controllers to have IP65 protection, the gasket must be properly installed
between the apparatus and the perimeter of the panel cut-out where it is to be fitted.

+
simultaneously. LEVEL 2
PARAMETERS programming is accessed. The first parameter of the selected menu is dis-
played on the screen.
- Press
key to access the next parameter and
key to return to the previous one.

keys simultaneously to ACCEPT THE NEW VALUE. The programming returns
to LEVEL 2 PARAMETERS.
To fix the unit, place the faste-
ners
1
over the sliders
2
as shown
in the figure. Move the fasteners
in the direction of the arrow. By
pressing tab
3
fasteners may be
moved in the opposite direction of
the arrow.
3.2 Connection:
See diagram on the unit rating plate.
The probe or 4-20 mA output converter and its leads should
NEVER
be installed in ducting
together with power, control or power supply wiring.
The power supply circuit must be connected with a minimum 2 A, 230 V switch located
close to the unit. Power supply cables must be H05VV-F 2x0,75 mm
2
or H05V-K 1x0,75 mm
2
.
Section of connecting wires for relays contacts must range from 1 mm
2
to 2.5 mm
2
.
NOTE: If no key is pressed for 25 seconds in either of the previous steps, the controller will
automatically return to the VALUE DISPLAY status without modifying any of the parameter
values.
