Control device classification: Independent mounting, with characteristic of
automatic operation action Type 1.B, to be used in clean situation, logical
medium (software) class A.
Double insulation between the power supply, the secondary circuit and the relay output.
3- INSTALLATION
The controller must be installed in a place protected from vibrations, water
and corrosive gases, and where the ambient temperature does not surpass
the value specified in the technical data.
In order the controllers be suitable having IP65 protection, the gasket should
be installed properly between the apparatus and the perimeter of the panel
cut-out where it is to be fitted.
In order to give a correct reading, the probe has to be installed in a place
without heat influences other than the temperature that is to be measured or
controlled.
3.1 Fastening:
To fix the unit, place the
fasteners
1
over the sli-
ders
2
as shown in the
figure. Move the faste-
ners in the direction of
the arrow. By pressing
tab
3
the fasteners may
be moved in the opposi-
te direction of the arrow.
3.2 Connection:
See diagram in the unit rating plate.
The probe and its lead should
NEVER
be installed in ducting along with
power, control or power supply wiring.
The power supply circuit should be connected with a minimum 2 A, 230 V,
switch located close to the unit. The cables should be of the type H05VV-F
2x0,75 mm
2
or H05V-K 0,75 mm

4- FRONT PANEL FUNCTIONS
UP key
When pressed for at least 5 seconds,
a manual defrost is started with pro-
grammed duration, (in thermostats
function).
In programming, it increases the dis-
played value.
DOWN key
In programming, it reduces the dis-
played value.
SET key
When pressed for at least 5 seconds, it displays the SET POINT tem-
perature value, (in thermostats function).
In programming, accept the programmed new value.
LED 1: Defrost in operation indicator.
(in thermostats function)
LED 2: Relay ON indicator.
(in thermostats function)
LED 2 flashing: Programming phase.
5- ADJUSTMENT AND CONFIGURATION
It should only be programmed or modified by personnel who are fully con-
versant with operation and possibilities of the equipment.
5.1 Set Point temperature.
The factory SET POINT default value is 0 ºC.
- Press key for at least 5 seconds to DISPLAY SET POINT. It displays the
CURRENT SET POINT value and LED “
2
” start flashing.
- Press or keys for CHANGE SET POINT to the required value.
- Press key to ACCEPT THE NEW SET POINT. The display returns to the
current temperature display status and the LED “
2
” stop flashing.
When
PA
appears in display, PASSWORD programmed in L5 parameter
should be enter for accede to the CURRENT SET POINT.
- Press key.
0
will be displayed to ENTER PASSWORD.
- Press or keys to CHANGE NUMBER and DISPLAY PASSWORD.
- Press key to ACCEPT PASSWORD. The CURRENT SET POINT value
will be displayed and possible to be modified.
REMARK:
If no key is pressed for 25 seconds in either of the previous steps,
the controller will automatically return to the current temperature display sta-
tus without modifying any of the parameters values.
5.2 Parameters configuration
Level 1 Parameters
- Press + keys simultaneously for at least 10 seconds. The LED “
2
” will
be flashing, we are in the LEVEL 1 PARAMETERS and in the display appe-
ar the first parameter “
C0
”.
- Press key to access the next parameter and key to return to the pre-
vious one.
- Pressing the key in the last parameter EP, the controller returns to the
current temperature display status and the LED “
2
” will stop flashing.
When
PA
appears in display, PASSWORD programmed in L5 parameter
should be enter for accede to programming LEVEL 1 PARAMETERS.
- Press key.
0
will be displayed to ENTER PASSWORD.
- Press or keys to CHANGE NUMBER and DISPLAY PASSWORD.
- Press key to ACCEPT PASSWORD. The first parameter “
C0
” will be dis-
played.
Level 2 Values
- To DISPLAY CURRENT VALUE of any parameter, select the required one
and press key. Once it is displayed, you can CHANGE VALUE pressing
or key.
- Press key to ACCEPT THE NEW VALUE. The programming returns to
LEVEL 1 PARAMETERS.
