TECHNICAL DATA
7.1 Technical data
Box: self-extinguishing grey.
Size: 53 x 90 x 58 mm (2.08 x 3.54 x 2.28 in, 3 DIN modules).
Installation: on DIN rail (it is not supplied by the builder).
Frontal protection: IP 40.
Connections: screw terminal blocks with pitch 5 mm (0.19 in) for cables up to
2.5 mm² (0.38 sq in, power supply, inputs and outputs), 5 poles single line female
connector with pitch 2.5 mm (0.09 in, serial port), 3 poles single line male connector
with pitch 2.5 mm (0.09 in, to remote indicator).
Ambient temperature: from 0 to 55 °C (32 to 131 °F, 10 ... 90% of relative humidity
without condensate).
Power supply: 230 Vac, 50/60 Hz, 2 VA (standard model) or 115 Vac, 50/60 Hz, 2 VA
(by request).
Alarm buzzer: included.
Measure inputs: 2 (cabinet and evaporator probe) for PTC or NTC probes.
Working range: from -50 to 99 °C (-58 to 210 °F) for PTC probe, from -40 to 99 °C
(-40 to 210 °F) for NTC probe.
Setpoint range: from -55 to 99 °C (-55 to 99 °F).
Resolution: 1 °C.
Display: one red LED 3-digit display 13.2 mm (0.51 in) high, compressor, evaporator
fan and defrost output status indicators.
Outputs: 4 relays: one 5 A @ 250 Vac relay for one ½ HP @ 230 Vac compressor
control (change-over contact), one 5 A @ 250 Vac relay for evaporator fan control
(NO contact), one 5 A @ 250 Vac relay for defrost system control (NO contact) and one
5 A @ 250 Vac relay for alarms control (the relay will be deactivated during the normal
operation and it will be activated during an alarm condition, change-over contact).
Kind of defrost: electric and hot gas defrost.
Defrost control: defrost interval, defrost end temperature and defrost maximum length
(automatic and by hand).

(2)
the unit of measure depends on the parameter db
(3)
unless the evaporator temperature is below the defrost end temperature you have set with the parameter d2, the defrost will not be activated
(4)
the instrument restores the normal operation once the dripping ends and the cabinet temperature gets the working setpoint
(5)
the evaporator fan stop temperature is “cabinet temperature - F1” ; you always have to consider the parameter F1 with positive sign.
Serial port: TTL with EVCOBUS communication protocol, adapt for serial interface
EC IFC 02 (for the configurer/cloner system CLONE and supervision system RICS).
