only as described in this document and never use itself as a security device. The device must be disposed of in accordance with local standards for the collection of
electrical and electronic equipment.
DESCRIPTION
FΑ3F is a temperature controller for freezer cabinets with defrost control; room and evaporator temperature is controlled with NTC/PTC sensors; 3 indication digits with resolution
0.5°C and 4 buttons; one serial input for controlling the cabinet’s door; 3 relays: compressor 30Α250VAC, fan 10Α250VAC, defrost 10Α250VAC; defrosting may be electric
or by hot gas; a buzzer in case of an alarm; the device is mounted on a panel hole and it is restrained with plastic side brackets; it can connect to the monitoring and controlling
network CAMIN via serial input using an interface with MODBUS protocol.

FA3F can connect to the memory key or to data logger model Mini Logger or to CAMIN network:
Memory key: parameter’s values can be downloaded to the memory key or can be uploaded to the thermostat from it.
Mini Logger: the thermostat can connect to a data logger and store temperatures, relay status and alarms to a microSD. A cable is used to connect the data logger with the
thermostat and parameter Add must be adjusted to 1.

CAMIN network: the thermostat can connect via a network interface NET-INS-485 to the CAMIN network. CAMIN is a software application designed to collect data, monitor
and fully control a network of up to 250 thermostats using cable wiring. It can also send SMS and emails in case of an alarm.
ATTENTION: according to safety standards, the device must be properly positioned and protected from any contact with electrical parts. The device must be fastened in such a way that it cannot
be removed without the use of tools. Disconnect the main safety switch of the installation before proceeding to any maintenance. Disconnect the power supply of the device before proceeding to
any maintenance. Do not place the device near heat sources, equipment containing strong magnets, in areas affected by direct sunlight or rain. Prevent electrostatic discharges and sharp objects
from been inserted to the device. Separate signal cables from power supply cables to prevent electromagnetic disorders. Signal cables must never be in the same pipe with the power supply cables.
ATTENTION: Read carefully the technical specifications and make sure that the working conditions are appropriate. According to safety standards, the device must be fastened in such a way that
it cannot be removed without the use of tools.
Dimensions are in mm. The device is mounted on panel hole with cut 29x71mm and restrained with plastic side brackets.
