FREQUENCY RESTRICTION 

 
When there’s no alarm activated, IPM red led blinks 1s ON and 5s OFF (if compressor running) or it is always OFF (if 
compressor is not running). This led is not collocated on the display but it’s situated on the IPM module, near the 
sensors. Otherwise, when the compressor is not working properly can view the following reports: 
 

SIGNAL DESCRIPTION 

RED LED  

T° discharge too high 

T° external heat-exchanger too high 

T° internal heat-exchanger too high 

T° internal heat-exchanger too low 

 

5.1

 

Protection against compressor discharge temperature too high: 

 

The  problem  is  indicated  by  the  sequence  of  5  blinks  of  red  light  of  IPM.  Specifically,  given  as  a  limit  value  of 
temperature 95 ° C is that: 
 

 

T°discharge ≤ 87°C 

  

 

there’s no frequency limitation; 

 

 

88°C < T°discharge < 92°C  

 

the rate of frequency grow is limited; 

 

 

93°C ≤ T°discharge ≤ 95°C  

 

the frequency stops growing; 

 

 

T°discharge > 96°C 

 

 

the frequency starts going down; 

In case of the compressor is running and T° dischar ge overtakes the 
limit, the compressor frequency is reduced to the minimum 
(compressor frequency reduction). The compressor frequency 
reduction starts 2 minutes after that the limit was overtaken.

 

 
In case of air-conditioner is turned on with T°discharge on the limit, compressor starts to work. The frequency is 
limited to the first compressor frequency target calculated by IPM MCU. Otherwise, it T°discharge is over the limit, 
frequency grows to the first compressor frequency target calculated by IPM MCU and, then, it reduces to minimum. 
 

 

5.1

 

Protection against external heat-exchanger temperature too high: 

 

When the protection is activated the IPM red led blinks 3 times; the limit reference in this case is 65°C and the 
frequency restriction are: 

 

 

T°ext. eat-exchanger ≤ 57°C   

 

there’s no frequency limitation; 

 

 

58°C < T°ext. heat-exchanger < 62°C    

the rate of frequency grow is limited; 

 

 

63°C ≤ T°ext. heat-exchanger ≤ 65°C   

the frequency stops growing; 

 

 

T°ext. heat-exchanger > 66°C   

 

the frequency starts going down; 

 

5.2

 

Protection against internal heat-exchanger temperature too high: 

 
Also for the reporting of the internal exchanger temperature too high the IPM red led blinks 3 times. Limit value is 
55°C for which apply the following considerations: 
 

 

T°int. heat-exchanger ≤ 47°C   

 

there’s no frequency limitation; 

 

 

48°C < T°int. heat-exchanger < 52°C    

the rate of frequency grow is limited; 

 

 

53°C ≤ T°int. heat-exchanger ≤ 55°C    

the frequency stops growing; 

 

 

T°int. heat-exchanger > 56°C    

 

the frequency starts going down;
