Etdu
Display unlock difference after finished defrost cycle
During defrost cycle it is possible that the tempera-
ture measured by the cell sensor (Pr1) rises exces-
sively (this depends on the position of the sensor
Pr1 to the evaporator).
In order to not indicate this rise, the functions con-
tained in the parameters
“dLo”
(display lock during
defrost cycle)
and
“Etdu”
(display unlock difference
after finished defrost cycle) are used.
The parameter “dLo” = Lb causes the indication
dEF
during a defrost cycle.
Completion of defrost cycle the indication
PdEF
is
suppressed, as the temperature Pr1 is always under
the value [”SP” + “Etdu”].
