PARAMETER LIST
REGULATION
Hy Differential:
(0,1÷25,5°C; 1÷45°F): Intervention differential for set point, always positive.
Compressor Cut IN is Set Point Plus Differential (Hy). Compressor Cut OUT is when the
temperature reaches the set point.
LS Minimum set point limit:
(-50,0°C
÷
SET; -58°F÷SET) Sets the minimum acceptable value for
the set point.
US Maximum set point limit:
(SET
÷
110°C; SET÷230°F) Set the maximum acceptable value for set
point.
OdS Outputs activation delay at start up:
(0÷255 min) This function is enabled at the initial start up
of the instrument and inhibits any output activation for the period of time set in the parameter.
(Light can work)
AC Anti-short cycle delay:
(0÷30 min) interval between the compressor stop and the following
restart.
CCt Thermostat override:
(0min ÷23h 50min) allows to set the length of the continuous cycle. Can
be used, for instance, when the room is filled with new products.
Con Compressor ON time with faulty probe:
(0÷255 min) time during which the compressor is active
in case of faulty thermostat probe. With COn=0 compressor is always OFF.
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.
CH Type of action:
CL = cooling; Ht = heating.
DISPLAY
CF Temperature measurement unit:
°C = Celsius; °F = Fahrenheit. When the measurement unit is
changed the SET point and the values of some 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
DEFROST
EdF Defrost mode:
in
=
interval mode
. The defrost starts when the time “
Idf
” is expired.
Sd
=
Smartfrost mode
. The time IdF (interval between defrosts) is increased only when the
compressor is running (even non consecutively).
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.
dFd Display during defrost:
rt
= real temperature;
it
= temperature reading at the defrost start;
Set
= set point;
dEF
= “dEF” label;
dEG
= “dEG” label;
dAd Defrost display time out:
(0
÷
255 min) Sets the maximum time between the end of defrost and
the restarting of the real room temperature display.
dPO First defrost after start-up:
y
= Immediately;
n
= after the IdF time
dAF Defrost delay after fast freezing:
(0min÷23h 50min) after a Fast Freezing cycle, the first defrost
will be delayed for this time.
ALARMS
ALC Temperature alarm configuration
rE
= High and Low alarms related to Set Point
Ab
= High and low alarms related to the absolute temperature.
ALU High temperature alarm setting:
ALC= rE, 0
÷
50°C or 90°F
ALC= Ab, ALL
÷
110°C or 230°F
when this temperature is reached and after the ALd delay time the HA alarm is enabled.
ALL Low temperature alarm setting:
ALC = rE , 0
÷
50 °C or 90°F
ALC = Ab , - 50°C or -58°F
÷
ALU
when this temperature is reached and after the ALd delay time, the LA alarm is enabled,.
AFH Temperature alarm differential:
(0,1÷25,5°C; 1÷45°F) Intervention differential for temperature
alarm set point, always positive.
ALd Temperature alarm delay:
(0÷255 min) time interval between the detection of an alarm condition
and the corresponding alarm signalling.
dAO Delay of temperature alarm at start-up:
(0min÷23h 50min) time interval between the detection
of the temperature alarm condition after the instrument power on and the alarm signalling.
EdA Alarm delay at the end of defrost:
(0
÷
255 min) Time interval between the detection of the
temperature alarm condition at the end of defrost and the alarm signalling.
PROBE INPUTS
Ot Thermostat probe calibration:
(-12.0
÷
12.0°C/ -21
÷
21°F) allows to adjust possible offset of the
thermostat probe.
OTHER
PbC Type of probe:
it allows to set the kind of probe used by the instrument:
PbC
= PBC probe,
ntC =
NTC probe.
rEL Release software:
(read only) Software version of the microprocessor.
Ptb Parameter table:
(read only) it shows the original code of the
dIXEL
parameter map.
Prd Probes display:
(read only) display the temperature.
Pr2 Access to the protected parameter list
(read only).

INSTALLATION AND MOUNTING
Instruments
XW40LS
shall be mounted on vertical panel, in a 150x31 mm hole, and fixed using two
screws
∅
3 x 2mm. To obtain an IP65 protection grade use the front panel rubber gasket (mod. RG-
LX). The temperature range allowed for correct operation is 0 - 60 °C. Avoid places subject to strong
vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to probes.
Let the air circulate by the cooling holes.

ELECTRICAL CONNECTIONS
The instruments are provided with Faston (2,8mm) to connect the analogue inputs. Relays and power
supply have a Faston connection (6,3mm). Heat-resistant cables have to be used. Before connecting
cables make sure the power supply complies with the instrument’s requirements. Separate the probe
cables from the power supply cables, from the outputs and the power connections. Do not exceed the
maximum current allowed on each relay, in case of heavier loads use a suitable external relay.
N.B.
Maximum current allowed for all the loads is 20A.
7.1
PROBE CONNECTIONS
The probe shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration.
It is recommended to place the thermostat probe away from air streams to correctly measure the
average room temperature.
8.
USE OF THE PROGRAMMING “HOT KEY “
The Wing units can UPLOAD or DOWNLOAD the parameter list from its own E2 internal memory to the
“Hot Key”
and vice-versa.
8.1
DOWNLOAD (FROM THE “HOT KEY” TO THE INSTRUMENT)
1.
Turn OFF the instrument by means of the ON/OFF key, remove the TTL serial cable if present,
insert the
“Hot Key”
and then turn the Wing ON.
