Description
PJEZ* (models S, Y, C) represent a range of electronic microprocessor controllers with LED display developed for
the management of refrigerating units, display cabinets and showcases.
•
PJEZS*, designed for the management of static refrigerating units, no fan on the evaporator, operating at
temperature above 0°C;
•
PJEZY*, designed for the management of static refrigerating units, no fan, operating at low temperatures;
•
PJEZC*, designed for the managements of low temperature ventilated refrigerating units.

Disposal of the product
The appliance (or the product) must be disposed of
separately in accordance with the local waste disposal
legislation in force.
Safety standards:
Installation precautions:
•
the connection cables must guarantee insulation up to
90 °C;
•
ensure a space of at least 10 mm between the case and
the nearby conductive parts;
•
digital and analogue input connections less than 30m
away; adopt suitable measures for separating the cables
so as to ensure compliance with the immunity standards;
Secure the connection cables of the outputs so as to avoid
contact with very low voltage parts.
NOTE: PJEZS*E* only support one NTC probe.
