Delay between
comp.
Time delay for couplings of two compressors. The
step delay is the time that has to elapse from the rst
compressor cuts in and until the next compressor can
cut in.

Step control mode
Selection of step control mode for compressors. At se-
quential mode compressor 1 will always be the rst to
start and the last to stop. In cyclic mode the run time
between the compressor will be equalized.

temp.
Fan stop temperature The function stops the fans in
an error situation, so that they will not provide power
to the appliance. If the defrost sensor registers a high-
er temperature than the one set here, the fans will be
stopped. There will be re-start at 2 K below the set-
ting. The function is not active during a defrost or
start-up after a defrost.
