The ECOLITE controller monitors certain application
limits of the compressor or switches the compressor off
to protect it as soon as the application limits are ex-
ceeded.
REF R404A R134a
dHA 62°C 70°C
When changing the refrigerant type (parameter Ert), the
ECOLITE controller sets the parameter SLA to the fol-
lowing presetting for the different refrigerants:
REF R404A R134a
SLA -45°C -25°C
If the cold store control is active, monitoring of the min-
imum and maximum overheating of the suction gas is
not possible and therefore deactivated.
