3.3  MEANING / FUNCTIONNING OF THE BOTTOM DISPLAY LED 
Led # 1 – 2 (With RTC) 
If the bottom display shows the RTC the leds are both blinking. 
Led # 1 – 2 In function Menu 
During the time counting to the next defrost for one or both circuits the leds are both blinking. 
LED during parameters programming 
In Pr2 level: led #3 indicates the visibility of the parameter; the led #1 and #2 show if the parameter 
can be modified or not. 
In  Pr3  level:  led  #3  and  #4  indicate  the  visibility  of  the  parameter;  the  led  #1  and  #2  show  if  the 
parameter can be modified or not. 
4  DISPLAY LAYOUT 
4.1  HOW TO READ THE MEASUREMENT LIST 
With the icon Cir1 on, push UP or Down keys to display the labels of the information of the circuit 1. 
With the icon Cir2 on, push UP or Down keys to display the labels of the information of the circuit 2. 
Each measurement is defined by a label that indicates which if it is a pressure a temperature or a time. 
4.2  READ PROBE VALUES OF CIRCUIT 1 OR 2 
To swap between the information of the two circuits use the UP and DOWN key to select a label then 
push SET, check the led. 
Example in fig.1 
Icon Cir1 is on: the top display shows the value of the output evaporator temperature (12.8°C) of the 
circuit 1; the bottom display shows Out 1 (outlet temperature evaporator 1). Push SET key to swap to 
the circuit 2. Fig2 
Icon Cir2 is on: the top display shows the value of the output evaporator temperature (11.7°C) of the 
circuit 2, the bottom display shows Out 2.
