PJEZ* (models S, C, Y and X) represent a range of electronic microprocessor
controllers with LED display developed for the management of refrigerating units,
display cabinets and showcases.
Models PJEZS* are designed for the management of static refrigerating
units (no fan on the evaporator) operating at temperatures above 0°C.
Models PJEZC* are designed for the management of low temperature
ventilated refrigerating units.
Finally, models PJEZ(Y, X)* are designed for the management
of static refrigerating units (no fan) operating at low temperatures.
Note: model Y= relays connected electronically internally; model X= independent
NTC or PTC probes 1 or 3 inputs.
Digital input as alternative to third probe
