Description
NO POWER
& SIGNAL
CABLES PJEZ* represents a range of electronic microprocessor controllers with LED display developed for the manage-
TOGETHER
ment of refrigerating units, display cabinets and showcases; are designed for the management of static refrigera-
ting units (no fan on the evaporator) operating at temperatures above 0°C.
Technical specifi cations
• Electronic controllers for normal temperature static refrigeration units
• Power supply 115Vac or 230Vac
• Ambient probe NTC
• Compressor relay 16A
Display and functions
During normal operation, the controller displays the value of the temperature read by probe. In addition, the
10
display has LED that indicate the activation of the control functions (see Tab. 1), while the 3 buttons can be used
3
to activate/deactivate some of the functions (see Tab. 2).
