DESCRIPTION
FΑ4F is a temperature controller for freezer cabinets with defrost control; room and evaporator temperatures are controlled with NTC/PTC sensors, with a temperature range
-50÷+110°C for NTC and -50÷+150°C for PTC;
30Α 250VAC, fan and auxiliary (lamp, buzzer, etc.) 10Α 250VAC, defrost 10Α 250VAC; defrosting may be electric or hot gas, a buzzer in case of an alarm. Smart defrost is
also available for power saving and better control of the defrost procedure. The device is mounted on a panel hole and it is restrained with plastic side brackets. Through the
serial input it can be connected to a network either through Cloud IoT on the CORTEX platform or through a local computer with the CAMIN program for complete local recording
and monitoring of the device.
