CONTROL OF EVAPORATOR FANS FOR SECTION 2 

Section 2 has 1 relay to control evaporator fan (26-27)   
The fan control mode is selected by means of the “

FnC2

” parameter: 

FnC2=C-n

  

fans will switch ON and OFF with the compressor 2and

 not run

 during defrost

:

FnC2= O-n

 

 fans will run continuously, but not during defrost  

 

After defrost, there is a timed fan delay allowing for drip time, set by means of the “Fnd2” parameter. 

FnC1=C-y

  

fans will switch ON and OFF with the compressor 2 and 

run

 during defrost; 

FnC1=O-y

  

fans will run continuously also during defrost 

 

An additional parameter “

FSt2

” provides the setting of temperature, detected by the evaporator probe 2, above which the fans are always OFF. This 

can be used to make sure circulation of air only if his temperature is lower than set in “FSt2”.
