DEFROST MAXIMUM LENGTH SETTING
To modify the defrost maximum length value to position the microswitch M4 on the desired

scale and to rotate the trimmer TR2 as long as the arrow indicates the desired value (for in-

stance to set a defrost maximum length of twenty-seven minutes to position the microswitch

M4 in position B and to rotate the trimmer TR2 as long as the arrow indicates the notch

12/27).
ADDITIONAL INFORMATIONS
-

the modification of the defrost maximum length value has not immediate effect; to

obtain this effect it must not be executed during the course of the value

the course of the defrost maximum length value gets recorded each 10 minutes

and it is stored in a non volatile memory even if a lack of power supply happens;

when the power supply recovers the instrument reproposes the last setting stored

if the defrost stopping digital input is activated the instrument never activates a

defrost cycle.

EVAPORATOR FANS STOPPAGE LENGTH SETTING
To modify the evaporator fans stoppage length to rotate the trimmer TR1 as long as the arrow

indicates the desired value (for instance to set an evaporator fans stoppage length of eight

minutes to rotate the trimmer TR1 as long as the arrow indicates the notch 8).
ADDITIONAL INFORMATIONS
-

the modification of the evaporator fans stoppage length value has not immediate

effect; to obtain this effect it must not be executed during the course of the value

the course of the evaporator fans stoppage length value gets recorded each 10

minutes and it is stored in a non volatile memory even if a lack of power supply
