9.  How to see and modify the set point(s) 

9.1  How to see the set point of compressors and/or fans 

If  the  controller  is  managing  both  compressors  and  fans,  both  the  set  points  are  displayed  in 
sequence, otherwise only the set point of the enabled section will be displayed. 
 
1) 

Push and release the 

SET 

key; 

2) 

The Lower display will show the 

“SEtC” 

label, while the Upper display will show its value. 

3) 

If second suction is configured, by pushing again the 

SET 

key the Lower display will show 

the 

“StC2” 

label, while the Upper display will show its value 

4) 

To see the fan set point, push again the 

SET 

key. 

5) 

The Lower display will show the 

“SEtF” 

label, while the Upper display will show the fan set 

point.  

To exit: 

push the 

SET key 

or wait for 30 without pressing any keys. 

 

9.2  How to modify the set point of compressors and/or fans 

 

******WARNING:  before  setting  the  target  set  points  for  the  first  time,  check  and,  if 
necessary,  modify  the  type  of  refrigerant  gas  (par.  FtyP)  and  the  default  unit  of 
measurement (par. dEU) for compressors and fans ********** 

 
PRE-ACTION 
1. 

Set the kind of refrigerant by means of the FtyP parameter (see 7.1 

How to set the kind 

of gas

)  

2. 

Set the measurement unit (dEU par.). 

3. 

Check and if necessary modify the set point limits (LSE and HSE par.). 

 
PROCEDURE

 

1. 

Push the 

SET 

key for more than 2 seconds; 

2. 

The  Lower  display  will  show  the 

“SEtC1” 

label,  will the  Upper  display  will  show  its  value 

flashing. 

3. 

To change the suction set point value, push the 

or 

n

 within 30s. 

4. 

To memorize the new value and pass to the fan set point, push the 

SET 

key. 

5. 

If the second circuit is enabled the Lower display will show the 

“SEtC2” 

label, will the Upper 

display will show its value flashing. 

6. 

To change the suction set point value, push the 

or 

n

 within 30s. 

7. 

To memorize the new value and pass to the fan set point, push the 

SET 

key. 

8. 

The Lower display will show the 

“SEtF” 

label, will the Upper display will show the fan set 

point flashing. 

9. 

To change its value, push the 

or 

n

 within 30s. 

 

To exit: 

push the 

SET key 

or wait for 30 without pressing any keys. 

 

10.  The INFO menu 

The controller can display some information directly from the main menu. 
The INFO menu is accessible by pushing and releasing the 

UP 

key: 

 
Here below the list of the information that can be displayed:
