Functions:
UP key
During programming, increases
the figure being displayed.
DOWN key
During programming, lowers
the figure being displayed.
+ Held down simultaneously for 10 seconds brings up the programming menu.
+ Held down simultaneously enters the new value.
Indicator LEDs:
LED 1
constant: Shows relay 1 is on.
flashing: Means relay 1 should be on according to the temperature detected by the probe,
but is not, owing to a programming condition.
LED 2
constant: Shows relay 2 is on.
flashing: Means relay 2 should be on according to the temperature detected by the probe,
but is not, owing to a programming condition.
LED PR
flashing: Programming set point or parameters.
The default (factory) setting for
SET POINTS 1 and 2 are 0ºC
- Hold the key down for 5 seconds. This opens the SP1 or SP2 setting menu (the PR led will flash).
- Press the
or
key to select SET POINT 1 or SET POINT 2.
- Press the
+
keys simultaneously to show the setting you want to change.
- Press the
or
keys to change the SET POINT to the figure you want.
- Press the
+
keys simultaneously to enter the new figure. When you do this, the display shows
the temperature again and the PR led stops flashing.
NOTE: If no key is pressed for 30 seconds during any of these steps, the controller automatically returns
to temperature display, neither of the SET POINTS being changed.

INSTALLATION:
Thermostat:
The thermostat must be installed in a place away from vibrations, water and corrosive gas and where the
ambient temperature is within the range in the technical specifications.
For protection level IP65, the joint between the device and the surrounding of the panel space where it is
installed must be properly made.

Fastening:
To fix the unit, place the fasteners 1
over the sliders 2 as shown in the figu-
re. Move the fasteners in the direction
of the arrow. By pressing tab 3, the
fasteners may be moved in the oppo-
site direction to the arrow.
TEMPERATURE SET POINT:
Parameters should only be programmed or chenged by personnel familiar with the operation of the
apparatus and its possibilities where applied.
Programming parameters:
Level 1:
-Hold the + keys down simultaneously for 10 seconds. The PR led will flash and the first parame-
ter, “P00”, will be shown on the display.
-Press the or key to change to the next parameter or previous parameter, respectively.
-When the final parameter EP is on the display, press the + keys simultaneously, the controller will
return to the temperature display and the PR led will stop flashing.
Level 2:
-To see the current value of any parameter, find the one you want and press the + keys simultane-
ously. When it is on display, you can change it with the or keys.
-Press the + keys simultaneously to set the new value. When you do this, the programming will return
to level 1 (parameters).

Probe:
For correct readings, the probe must be installed in a place free of thermal
effects other than the temperature to be measured or controlled.
This diagram shows how the probe must be connected:
