3.2 REGULATION
Once set a desired temperature required for the products storage within the operational range of
each models, the regulation of the cooling system is controlled by the temperature measured by
the control probe with a positive differential from the set point: when the temperature rises up to the
set point plus differential the compressor starts to pull down the temperature and it turns off when
the desired set point is reached again.
In case of faulty probe the compressor activation is timed through the parameter “ C4” and “C5”
