DEF.
Ad
Net address
for connection to TeleNET
supervision system or Modbus
0 ÷ 31 (with SEr=0)
1 ÷ 247 (with SEr=1)
0
SEr
RS-485 communication protocol
0 = TeleNET protocol
1 = Modbus-RTU protocol
0
Bdr
Modbus baudrate
0 = 300 baud
1 = 600 baud
2 = 1200 baud
3 = 2400 baud
4 = 4800 baud
5 = 9600 baud
6 = 14400 baud
7 = 19200 baud
8 = 38400 baud
5
Prt
Modbus parity check
0 = none
1 = even
2 = odd
0
Ald
Minimum
and
maximum
temperature
signalling and alarm display delay
0 ÷ 240 min
120 min
C1
Minimum time between shutdown and
subsequent
switching
on
of
the
compressor
.
0 ÷ 15 min
0 min
CAL
Cold room sensor value correction
-10,0 ÷ +10,0 °C
0,0 °C
CE1
Duration of compressor ON time in the
case of faulty ambient probe
(emergency
mode).
If CE1=0 the emergency mode in the
presence of error E0 remains disabled, the
compressor remains off and defrosting is
prevented in order to conserve the remaining
cold.
0 ÷ 240 min
0 = disabled
0 min
CE2
Duration of compressor OFF time in the
case of faulty ambient probe
(emergency
mode).
5 ÷ 240 min
5 min
doC
Compressor safety time for door switch:
when the door is opened the evaporator fans
shut down and the compressor will continue
working for time
doC
, after which it will shut
down.
0 ÷ 5 min
0 min
tdo
Compressor
restart
time
after
door
opening:
when the door is opened and after
tdo time, it’s setted back the normal
functioning giving door open alarm (Ed)
If the door switch is closed and the light stays
on for a longer time than tdo light cell alarm is
signalled (E9).
With tdo=0 the parameter is disabled.
0 ÷ 240 min
0 = disabled
0 min
Fst
FAN shutdown TEMPERATURE
The fans will stop if the temperature value
read by the
evaporator
sensor is higher than
this value.

-45 °C
HSE
Maximum value attributable to setpoint.
