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.
