Installation and Operation Manual
Lod
Instrument display
(P1; P2, P3, P4, SET, dtr) 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 = setpoint; dtr = percentage
of visualization.
rEd
X-REP display (optional)
(P1; P2, P3, P4, SET, dtr) Selects which probe is displayed
by X- REP. P1 = Thermostat probe; P2 = Evaporator probe;
P3 = Third probe (only for model with this option enabled);
P4 = Fourth probe, SET = setpoint; dtr = percentage of
visualization.
dLY
Display delay
(0 to 20min00s; res. 10s) When the temperature increases,
the display is updated of 1°C or 1°F after this time.
dtr
Percentage of the second and first probe for
visualization when Lod=dtr
(0 to 99; 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; in) EL = electrical heater; in = hot gas
dFP
Probe selection for defrost termination
(nP; P1; P2; P3; P4) nP = no probe; P1 =thermostat probe; P2
= evaporator probe; P3 =configurable probe; P4 = Probe on
Hot Key plug
dtE
Defrost termination temperature
(-50 to 50°C; -58 to 122°F) (enabled only when EdF=Pb) Sets
the temperature measured by the evaporator probe, which
causes the end of defrost.
idF
Interval between defrost cycles
(0 to 120hours) Determines the interval of time between two
defrost cycles.
MdF
(Maximum) length for defrost
(0 to 255min) When P2P=n, (not evaporator probe: timed
defrost) it sets the defrost duration. When P2P=Y (defrost end
based on temperature) it sets the maximum length for defrost.
dSd
Start defrost delay
(0 to 99min) This is useful when different defrost start times
are necessary to avoid overloading the plant.
dFd
Temperature displayed during defrost
(rt; it; SEt; dEF) rt = real temperature; it = temperature at
defrost start; SEt = setpoint; dEF = “dEF” label.
dAd
MAX display delay after defrost
(0 to 255min) Sets the maximum time between the end of de-
frost and the restarting of the real room temperature display.
Fdt
Drip time
(0 to 120min) Time interval between reaching defrost termi-
nation 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
(n; Y) n = after the idF time, Y = immediately
dAF
Defrost delay after continuous cycle
(0.0 to 24h00min, res. 10min) Time interval between the end
of the fast freezing cycle and the following defrost related to it.
FANS
FnC
Fans operating mode
(C-n; o-n; C-Y; o-Y) C-n = runs with the compressor, OFF
during defrost; o-n = continuous mode, OFF during defrost;
C- Y = runs with the compressor, ON during defrost; o-Y =
continuous mode, ON during defrost.
Fnd
Fans delay after defrost
(0 to 255min) Interval between end of defrost and evaporator
fans start.
Fct
Temperature differential to avoid fan short cycles
(0 to 59°C; 0 to 90°F) (N.B.: if Fct=0 function disabled) If the
difference of temperature between the evaporator and the
room probes is higher than Fct value, the fans will be switched
ON.
