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 differential; 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 differential. 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 off (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 difference for destratification fans. If the difference |Pb1-Pb3| as an absolute value (positive number) 
is greater than SFd, the destratification fans are started. They switch off when |Pb1-Pb3| is less than SFd -diS 

(destratification fans differential)

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).

CONFIGURATION 

NOTE: the instrument must be switched off and restarted each time these parameters are modified.

H00

Probe type selection, PTC/NTC. 0 = PTC; 1 = NTC.

0/1

H09

Type of dehumidification. 0= with dehumidification relay; 1= with dehumidification relay + compressor; 2= 

without dehumidification relay; 

0/1/2

0

H42

Pb2 Evaporator probe presence. 0 = not present; 1 = present.
