Our factory settings give the following minimum evaporation temperatures: positive temperature units: -13º negative temperature units: -35º When the cooling demand is under 10% of the nominal capacity, the evaporation pressure curve falls to the minimum value allowed by the compressor, switching the low pressure switch off ( and points) and switching off the compressor.
