dPO
Defrost enabling request from power-on
Determines whether or not the instrument must defrost at power-up
(provided that the temperature measured at the evaporator will allow defrost).
n
(0) = no, does not start defrosting at power-on;
y
(1) = yes, starts defrost at power-on

FCO
Evaporator fans operating mode. The status of the fans will be:
A compressor ON fans thermoregulated, A compressor OFF depends on FCO

CA1
Calibration of probe Pb1.
Positive or negative temperature value added to the value read by Pb1. This sum is used for both
temperature display and temperature regulation purposes.

CA2
Calibration of probe Pb2.
Positive or negative temperature value added to the value read by Pb2. This sum is used for both
temperature display and temperature regulation purposes.
