LITE PARAMETER TABLE
This section describes the most useful parameters, which are contained in the 'Lite' folder. For a description of all User (USr) and Installer (Ins)
parameters, see the user manual. Note: the 'Lite' folder parameters are NOT divided into subfolders and are always visible (no access password
is required). The same parameters are also visible in the respective folders 'Compressor', 'Fans', etc. (also indicated here for easy reference) in the
User (USr) and Installer (Ins) parameters menu.

DESCRIPTION
RANGE
DEF. / U.o.M.
SP1
SETPOINT Control value within the range between the minimum set point LSE and the maximum set point HSE.
LSE...HSE
0.0 °C/°F
diF
Compressor relay activation dierential; the compressor stops on reaching the set point value (as indicated by the
regulation probe) and restarts at a temperature value equal to the set point plus the value of the dierential. Note:
the value 0 cannot be set.
0.1...30.0 2.0 °C/°F
HSE
Maximum value that can be assigned to the setpoint.
LSE...302
50.0 °C/°F
LSE
Minimum value that can be assigned to the setpoint.
-55.0...HSE
-50.0 °C/°F
SPH
Humidity setpoint. Minimum LSH value that can be assigned to the setpoint. Maximum HSH value that can be
assigned to the setpoint.
LSH...HSH 0.0 %RH
dbH
Humidity intervention half-band. Always positive.
0.0...50.0
5.0 %RH
dtY
Type of defrost.
0= electric defrosting - compressor o (OFF) during defrosting
1 = reverse cycle defrost (hot gas) - compressor ON during defrosting
2= Free: defrosting independently of compressor
0/1/2 0
dit
Interval between the start of two subsequent defrosting cycles.
0= function disabled (defrosting NEVER performed)
0...250 6 h
dEt
Defrost time-out; determines the maximum duration of the defrost cycle.
1...250
30 min
dSt
Defrost end temperature (determined by the evaporator probe Pb2).
-50.0...150
6.0 °C/°F
FSt
Fan stop temperature; if the evaporator probe reads a higher value than the set value, the fans are stopped. The
value is either positive or negative and, depending on parameter FPt, can be either the absolute temperature or
the temperature relative to the set point.
-50...150 6.0 °C/°F
Fdt
Fan activation delay after a defrosting cycle.
0...250
0 min
dt
Drip time.
0...250
0 min
dFd
Allows exclusion of the evaporator fans to be selected or not selected during defrosting. y = yes; n = no.
n/y
y
F09
Minimum setpoint for condenser fan speed.
-50.0...99.9
30.0 °C/bar
SFd
Temperature dierence for destratication fans. If the dierence |Pb1-Pb3| as an absolute value (positive number)
is greater than SFd, the destratication fans are started. They switch o when |Pb1-Pb3| is less than SFd -diS
(destratication fans dierential)
0...99.9 4.0 °C/°F
HAL
Maximum temperature alarm. Temperature value (intended either as distance from set point or as an absolute
value based on Att) which, if exceeded in an upward direction, triggers the activation of the alarm signal.
LAL...150 50.0 °C/°F
LAL
Low temperature alarm. Temperature value (intended as distance from the set point or as an absolute value based
on Att) which, when exceeded downwards, triggers the activation of the alarm signal.
-50.0...HAL -50.0 °C/°F
dAO
Temperature alarm exclusion time after defrost.
0...999
60 min
tAO
Time delay for temperature alarm indication. Refers to high/low temperature alarms only.
0...250
0 min
CA1
CA2
CA3
CA4
Calibration 1/2/3/4.
Positive or negative temperature value added to the value read by probe Pb1/2/3/4, according to the setting of
parameter “CA”.
-12.0...12.0 0 °C/°F
ddL
Display mode during defrost.
0 = displays the temperature read by the room probe Pb1;
1 = locks the reading at the temperature value read by room probe Pb1 when defrosting starts and until the next
time the set point value is reached;
2 = displays the label “deF” during defrosting and until the next time the set point value is reached (or until Ldd
has elapsed).
0/1/2 1
CONFIGURATION NOTE: the instrument must be switched o and restarted each time these parameters are modied.
H00
Probe type selection, PTC/NTC. 0 = PTC; 1 = NTC.
0/1
1
H09
Type of dehumidication. 0= with dehumidication relay; 1= with dehumidication relay + compressor; 2=
without dehumidication relay;
0/1/2 0
H42
Pb2 Evaporator probe presence. 0 = not present; 1 = present.
