Particular situations
Optimizing consumption
Temperature adjustment follows different rules if the following conditions occur:
• ECO function On
• Temperature (ambient) measured by the sensor on the electronic board of between
25 and 35 °C
• Time elapsed from last door opening more than 22 hours
• Duration of last compressor On cycle less than 45 min
The previous conditions are tested whenever the compressor is switched off. If all these
conditions have occurred, with every demand for refrigeration by one compartment,
also the other compartment is forced to demand refrigeration (thus offering energy
saving, as the compressor is switched on less often), considering as switching Off
thresholds those set by the user.
This particular situation can be exited if at least one of the previous conditions has not
occurred again on switching off of the compressor, or if the situation continues for
more than 255 days.
After a defrost
After every defrost, a refrigeration demand from the freezer compartment is forced,
without waiting for the freezer air sensor to detect a hotter value than the switching
on temperature relevant to the adjustment set by the user. The end of the demand
is managed following the classic rules of thermostatting.
