DESCRIPTION
Preset Value
SCL
1°C;
2°C;
°F
Readout scale.
1°C (with INP=SN4 only): measuring range -50/-9.9 … 19.9/80°C
2°C : measuring range -50 … 120°C
°F : measuring range -55 … 240°F
Caution: upon changing the SCL value, it is then absolutely necessary to re-configure the parameters
relevant to the absolute and relative temperatures (SPL, SPH, SP, ALA, AHA, etc..).
°F
SPL
-50..SPH
Minimum limit for SP setting.
41
SPH
SPL.120°
Maximum limit for SP setting.
64
SP
SPL... SPH
Setpoint (value to be maintained in the room).
59
C-H
REF; HEA
Refrigerating (REF) or Heating (HEA) control mode.
REF
HYS
1...10°
OFF/ON thermostat differential
Refrigerating control (C-H=REF) Heating control (C-H=HEA)
5
CRT
0...30min
Compressor rest time. The output is switched on again after CRT minutes have elapsed since the
previous switchover. We recommend to set CRT=03 with HYS<2.0°.
6
CT1
0...30min
Thermostat output run when probe T1 is faulty. With CT1=0 the output will always remain OFF.
3
CT2
0...30min
Thermostat output stop when probe T1 is faulty. With CT2=0 and CT1>0 the output will always be ON.
Example: CT1=4, CT2= 6: In case of probe T1 failure, the compressor will cycle 4 minutes ON and 6
minutes OFF.
6
CSD
0..30min
Compressor stop delay after the door has been opened (active only if DS=YES).
6
DFR
0... 24(1/24h)
Defrost frequency expressed in cycles/24 hours.
3
DLI
-50...120°
Defrost end temperature.
39
DTO
1...120min
Maximum defrost duration.
20
DTY
OFF;
ELE;
GAS
Defrost type
OFF: off cycle defrost (Compressor and Heater OFF).
ELE: electric defrost* (Compressor OFF and Heater ON).
GAS: hot gas defrost* (Compressor and Heater ON).
* The defrost output is active if only OAU=DEF.
OFF
DRN
0...30min
Pause after defrost (evaporator drain down time).
0
DDY
0...60min
Display during defrost. If DDY=0 during defrost the temperature continues to be displayed. If DDY > 0,
during defrost the display shows DEF, and at the end of defrost it shows REC for DDY minutes.
1
FID
NO/YES
Fans active during defrost.
YES
FDD
-50...120°
Evaporator fan re-start temperature after defrost.
32
FTC
NO/YES
Optimised fan control enabling. With FTC = NO the fans remain on all the time.
Fig. 2 Optimised fan control (FTC=YES)
YES
FT1
0...180sec
Fan stop delay after compressor stop. See Fig. 2.
180
FT2
0...30min
Timed fan stop. With FT2=0 the fans remain on all the time.
1
FT3
0...30min
Timed fan run. With FT3=0, and FT2 > 0, the fans remain off all the time.
