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.
Fastening
To fix the unit, place the fasteners 1 over the sliders 2 as shown in
max.
the figure. Move the fasteners in the direction of the arrow. By

5-.Adjustment and configuration

It should only be programmed or modified by personnel who are fully conversant with
operation and possibilities of the equipment.

5.1-.Set Point temperature

The factory SET POINT default value is 0 ºC.
-Press SET key for at least 5 seconds to DISPLAY SET POINT. It displays the CURRENT SET
POINT value and LED "2" start flashing.
-Press N or Q keys for CHANGE SET POINT to the required value.
-Press SET 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 SET key. 0 will be displayed to ENTER PASSWORD.
-Press N or Q keys to CHANGE NUMBER and DISPLAY PASSWORD.
-Press SET key to ACCEPT PASSWORD. The CURRENT SET POINT value will be displayed
and possible to be modified.

5.2-.Parameters configuration

Level 1 Parameters
-Press N + Q keys simultaneously for at least 10 seconds. The LED "2" will be flashing, we
are in the LEVEL 1 PARAMETERS and in the display appear the first parameter "C0".
-Press N key to access the next parameter and Q key to return to the previous one.
-Pressing the SET 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 SET key. 0 will be displayed to ENTER PASSWORD.
-Press N or Q keys to CHANGE NUMBER and DISPLAY PASSWORD
-Press SET key to ACCEPT PASSWORD. The first parameter "C0" will be displayed.
Level 2 Values
-To DISPLAY CURRENT VALUE of any parameter, select the required one and press SET key.
Once it is displayed, you can CHANGE VALUE pressing N or Q key.
-Press SET key to ACCEPT THE NEW VALUE. The programming returns to LEVEL 1
