10 WORKING SET POINT and CONFIGURATION PARAMETERS
10.1 Configuration parameters
Insulation class: 2.
Maintenance of clock data in absence of power supply: 24 hours (if
battery starts with full charge).
Battery charge time: 2 minutes without interruptions (the battery is
charged by the device power supply)
.
Alarm buzzer
Measure inputs: 2 (cabinet probe and evaporator probe) for PTC/
NTC probes.
Digital inputs: 1 (microport) for NO/NC contact (clean contact, 5 V, 1
mA); fourth input can be configured as sensor input (display probe or
condenser probe, for PTC/NTC probes) or digital input (multifunc
-
tion, clean contact, 5V, 1 mA).
Working range: from -50 to 150°C (-50 to 300°F) for PTC probe, from
-40 to 105°C (-40 to 220°F) for NTC probe.
Resolution: 0.1°C/1°C/1°F.
Digital outputs - 4 relays:
• compressor relay: 16 A res. @ 250 VAC, 5 FLA, 30 LRA (exchange
contacts)
• defrost relay: 8 A res. @ 250 VAC, 2 FLA, 12 LRA (exchange contacts)
• evaporator fan relay: 8 A res. @ 250 VAC, 2 FLA, 12 LRA (NO contact)
• fourth output: 8 A res. @ 250 VAC, 2 FLA, 12 LRA (exchange contacts).
The maximum current allowed on the load is 10 A.
Serial port:
port for communication with a management system
(through a serial interface, via TTL, with Modbus communication
protocol) or with the programming key.
