6.4 REGULATIONS
Compressor
The compressor can be active only in START function when the room probe has no error.
If the presence of door is on (PI=I), the door must be closed to permit the starting of the compressor only
if P6=0. With P6=0 the compressor is active even if the door is open and with arrested fan. The compressor
starts according to the SET POINT on, corresponding to the selected cycle and according to the differential of
temperature set (Parameter P8).
The protection time for the compressor are:
• P9: minimum delay that must exist between the switching off and the next starting up of the compressor.
This parameter is used also like reset of the card.
• P10: minimum delay that must exist between 2 consecutive starting ups of the compressor.
Manual defrosting
The defrosting is carried out with open door, without the use of neither the heater nor the hot gas.
Parameters
Pressing contemporarily Up and Down to enter the parameter setting for at least 4 sec.
At this point on the display appears the number itself of the parameter (P0). Pressing the SET
key, it is pos-
sible to see the value of the parameter itself and modify it.
THE KEYS UP AND DOWN
, WHEN THE PARAMETER SETTING IS ON, ALLOW TO PASS TO THE NEXT/FORMER PARAMETER; WHEN THE
VALUE OF THE PARAMETER IS ON, THEY MODIFY IT.
