1. 

:

 Used for setting the Set point (short press) and for 

programming the function parameters (pressed for 5 s).  
In programming mode is used to enter in parameters edit 
mode and confirm the values.  In programming mode 
can be used together with the 

 key to change the pro-

gramming level of the parameters.  When the keyboard is 
locked, the keys 

 and 

 used together (hold pressed 

for 5 s), unlock the keyboard.

2. 

/Aux:

 In programming mode is used for decreasing the 

values to be set and for selecting the parameters.   
If programmed with parameter 

tFb

 can perform, when 

pressed for 1 s during normal operation mode, other 
functions as 

switching

 between 

Normal/Eco

 mode and 

turn

 

ON/OFF

 (Stand by) the controller (see “Functions of 

keys  /  and  /Aux”).

3. 

/

:

 In normal mode (pressed for 5 s) can be used 

to 

start/stop manual defrosting

 (

)

.  In programming 

mode is used for increasing the values to be set and for 
selecting the parameters.  In programming mode can be 
used together with 

 key to change parameters level.  

Pressed together with the 

 key for 5 s allows the key-

board unlock.

4. 

/ :

 Used (short press) for displaying the instrument 

variables (measured temperatures etc.).  In programming 
mode can be used to return in normal mode (hold for 2 s).   
If programmed with parameter 

tFb

 can perform, when 

pressed for 1 s during normal operation mode, other 
functions as 

switching

 between 

Normal/Eco

 mode and 

turn

 

ON/OFF

 (Stand by) the controller (see “Functions of 

keys  /  and  /Aux”).

5.  LED dp/Stand by:

 When the instrument is placed in 

Stand by mode, this is the only lighted LED.  During the 
normal operation is the decimal point  In programming 
mode, while the parameter code is displayed, the dot 
indicates the parameter protection level: 

not protected 

(lit up), 

protected

 (flashing) and 

hidden

 (turned OFF).

6.  LED 

: Indicates the output status (compressor or 

temperature control device) when the instrument 
is programmed for 

cooling operation

ON

 (lit up), 

OFF

 (turned OFF) or 

inhibited

 (flashing).

7.  LED  :

 Indicates the output status (compressor or temper-

ature control device) when the instrument is programmed 
for 

heating operation

ON

 (lit), 

OFF

 (turned OFF) or 

inhib-

ited

 (flashing).

8.  LED  :

 Indicates the 

alarm status

ON

 (lit), 

OFF

 (turned OFF) or 

silenced

 (flashing).

9.  LED  :

 Indicates that the 

defrost

 is 

in progress

.

2.  PROGRAMMING

2.1 

Fast Set point programming

The normal mode to program the setpoint is done by mo-
mentarily pressing the 

 key, the display shows 

SP

 (or 

SPE

alternated to the programmed value.
To change it press the 

 key to increase the value or 

 to 

decrease it
These keys increase or decrease the value one digit at a 
time, but if the button is pressed for more than one sec-
ond the value increase or decreases rapidly and after two 
seconds the speed increases even more in order to quickly 
reach the desired value.
However, through 

ted

 parameter you can determine if and 

which Set point can be set with the 

 key rapid procedure.

The parameter can have the following values:

oF

  SP/SPE cannot be changed with the 

 key rapid proce-

dure (pressing/releasing the 

 key, nothing happens);

1

  Only SP can be set with this procedure (“normal” Set Point);

2

  Only SPE can be set with this procedure (“economic”/

Eco Set Point);

3

  Both SP and SPE can be set with this procedure;

4

  To select the Active Setpoint (SP or SPE).

For example, in case the parameter 

TEd

 = 

1

 or 

3

, the proce-

dure is the following:
Press and release the 

 key, the display shows 

SP

 alter-

nated to the Set Point value.  To change the Set Point, press 
the 

 key to increase the value or 

 to decrease it

If only Set Point 1 is present (

TEd

 = 

1

), once the desired 

value is set, press the 

 button to exit the fast program-

ming mode.
If also the “Economic” Set Point (

TEd

 = 

3

) can be set, press-

ing and releasing again the 

 button the display shows 

SPE

 

alternated to its programmed value.
To change the value use the 

 and 

 keys as for the 

SP

 

Set Point value.  Once the desired value is correctly set, 
press the 

 button to exit the fast Set Point change.

To exit the fast Setpoint programming mode push the 

 

key after the last Set Point has been displayed or pressing 
no buttons for about 10 s, after which the display returns to 
normal operation.

2.2 

Standard mode parameters programming

To access the instrument function parameters when pass-
word protection is disabled, press the key 

 and keep it 

pressed for about 5 seconds, after which the display shows 
the code that identifies the first programmable parameter
The desired parameter can be selected using the 

/

 keys, 

then, pressing the 

 key, the display shows the parameter 

code alternated to its value that can be changed with the 

 

and 

 keys.

Once the desired value has been set, press the key 

 

again: the new value is stored and the display shows only 
the code of the selected parameter
Pressing the 

 and 

 keys, it is possible to select another 

parameter and change it as described.
