Operation with different measuring and indicated value 

 

General notes 

 
Parameters A15 and A35 permit the independent selection of measured and indicated value. 
There are the possibilities temperature measuring with temperature display, temperature 
measuring with pressure display, pressure measuring with pressure display and pressure 
measuring with temperature display. 
 
The measuring values are converted continuously in the equivalent value of the other unit, the 
latter can be indicated for 3 seconds by pressing shortly the display key. This conversion always 
takes place considering the refrigerant selected with parameter A37. 
Note that longer pressing the display key switches the display over to power display. 
 
With parameter A38 and A39 the range of the pressure measuring is defined. Regardless of this 
the operating range of the controller is 0.0 … 30.0 bar. In case of temperature measuring with 
pressure display and pressure measuring with temperature display the exceeding of this range 
leads to the indication of “F b” in the display.  Just as “F 1” in case of sensor error this message 
switches off the control. 
 
The control parameters exist only once for temperature or pressure values in (not erasable) 
EEPROM memory, therefore parameters are reset to harmless values at each change of the 
display value with parameter A15. 
When switching over to pressure display the reset values depend on the select refrigerant. If the 
refrigerant is changed with parameter A37 if pressure display is already selected with parameter 
A15, the values are reset again according this refrigerant.  
The reset values are listed below.
