Variables
Meaning
Value
Default
dFd
Display viewing during Defrost
0 = current temperature
1 = temperature at the start of the defrost
2 = “DEF”
1
Ad
Modbus Network address
0 – 247
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
8
Prt
Modbus parity check
0 = none
1 = even
2 = odd
1
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 – 10 °C
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 signaled (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 – 99 °C
99 °C
Fd
Fst differential
1 – 10 °C
2 °C
LSE
Minimum value attributable to setpoint.
-45 – (HSE-1) °C
-45 °C
HSE
Maximum value attributable to setpoint.
(LSE+1) – 99°C
99 °C
AU1
Auxiliary/alarm relay 1 control
-6 (NC) = relay de-energised during stand-by.
-5 (NC) = Contact for casing element control
(AUX relay closed with compressor
output inactive).
-4 (NC) = pump down function(NC, see CHAP
5.16).
-3 (NC) = automatic auxiliary relay managed by
StA temp. setting with 2°C differential
(NC).
-2 (NC) = manual auxiliary relay controlled via
AUX key (NC).
-1 (NC) = alarm relay (NC).
0 = relay deactivated.
1 (NO) = alarm relay (NO).
2 (NO) =manual auxiliary relay controlled via
AUX key (NO).
3 (NO) = automatic auxiliary relay managed by
StA temp. setting with 2°C differential
(NO).
4 (NO) = pump down function (NO, see CHAP
5.16).
5 (NO) = free voltage contact for condensing
unit (AUX relay and compressor relay
in parallel).
6 (NO) = relay excited during stand-by.
-1
AU2
Auxiliary/alarm relay 2 control
(like AU1 )
5
StA
Temperature setting for auxiliary relay
-45 – 99 °C
0 °C
nSC
Correction factor for the SET button during night operation
(energy saving)
(with In1 or In2 = 8 or -8)
During night operation the control set is: Set Control = Set + nSC
In night mode decimal point flashes.
-20 – 20 °C
0 °C
