dIXEL
COF Compressor OFF time with faulty probe: (0÷255 min) time during which the compressor is off
in case of faulty thermostat probe. With COF=0 compressor is always active.
DISPLAY
CF Temperature measurement unit: °C = Celsius; °F = Fahrenheit . When the measurement unit
is changed the SET point and the values of the regulation parameters have to be modified
rES Resolution (for °C): (in = 1°C; de = 0,1°C) allows decimal point display.
dE = 0,1°C
in = 1 °C
rEd Remote display : select which probe is displayed by the remote display ( T620or CX620 or
V620)
(P1; P2, P3, P4, SET, dtr): it selects which probe is displayed by the instrument: P1 =
Thermostat probe; P2 = Evaporator probe; P3 = Third probe(only for model with this option
enabled); P4 = Fourth probe, SET = set point; ; dtr = percentage of visualization.
dLy Display delay: (0 ÷20.0m; risul. 10s) when the temperature increases, the display is updated of
1 °C/1°F after this time.
dtr Percentage of the second and first probe for visualization when Lod = dtr (0÷100; 100 =
P1, 0 = P2 ): if Lod = dtr it allows to set the visualization according to the percentage of the first
and second probe, as for the following formula (dtr(P1-P2)/100 + P2).
DEFROST
tdF Defrost type:
EL = electrical heater (Compressor OFF)
in = hot gas (Compressor and defrost relays ON)
dFP Probe selection for defrost termination: nP = no probe; P1 =thermostat probe; P2 =

evaporator probe is present) sets the temperature measured by the evaporator probe which
causes the end of defrost.
IdF Interval between defrosts: (1÷120h) Determines the time interval between the beginning of two
defrost cycles.
MdF (Maximum) duration of defrost: (0÷255 min) When P2P = n, no evaporator probe, it sets the
defrost duration, when P2P = y, defrost end based on temperature, it sets the maximum length
for defrost.

the restarting of the real room temperature display.
Fdt Drain down time: (0÷60 min.) time interval between reaching defrost termination temperature
and the restoring of the control's normal operation. This time allows the evaporator to eliminate
water drops that might have formed due to defrost.
dPo First defrost after start-up:

Fnd Fan delay after defrost: (0÷255 min) The time interval between the defrost end and evaporator
fans start.
Fct Temperature differential avoiding short cycles of fans (0÷59°C; Fct=0 function disabled). If
the difference of temperature between the evaporator and the room probes is more than the
value of the Fct parameter, the fans are switched on.
FSt Fan stop temperature: (-50÷110°C; -58÷230°F) setting of temperature, detected by evaporator
probe, above which the fan is always OFF.
Fon Fan ON time: (0÷15 min) with Fnc = C_n or C_y, (fan activated in parallel with compressor). it
sets the evaporator fan ON cycling time when the compressor is off. With Fon =0 and FoF ≠ 0
the fan are always off, with Fon=0 and FoF =0 the fan are always off.
FoF Fan OFF time: (0÷15 min) with Fnc = C_n or C_y, (fan activated in parallel with compressor). it
sets the evaporator fan off cycling time when the compressor is off. With Fon =0 and FoF ≠ 0 the
fan are always off, with Fon=0 and FoF =0 the fan are always off.

i1P Digital input polarity: oP: the digital input is activated by opening the contact; CL: the digital
input is activated by closing the contact.
i1F Digital input configuration: EAL = external alarm: "EA" message is displayed; bAL = serious
alarm "CA" message is displayed. PAL = pressure switch alarm, "CA" message is displayed; dor

Ptb Parameter table: (read only) it shows the original code of the dIXEL parameter map.
7. Digital input
The free voltage digital input is programmable in different configurations by the "i1F" parameter.
DOOR SWITCH INPUT (i1F = dor)
It signals the door status and the corresponding relay output status through the "odc" parameter: no =
normal (any change); Fan = Fan OFF; CPr = Compressor OFF; F_C = Compressor and fan OFF.
Since the door is opened, after the delay time set through parameter "did", the door alarm is enabled,
the display shows the message "dA" and the regulation restarts is rtr = yES. The alarm stops as
soon as the external digital input is disabled again. With the door open, the high and low temperature
alarms are disabled.
GENERIC ALARM (i1F = EAL)
As soon as the digital input is activated the unit will wait for "did" time delay before signalling the "EAL"
alarm message. The outputs status don't change. The alarm stops just after the digital input is de-
activated.
