2. General description

Model XW20K is microprocessor based controller suitable for applications on normal or medium

temperature refrigerating units. It has to be connected by means of a two-wire cable (∅ 1mm) at a

distance of up to 30 meters to the keyboard T620 or V620 or CX620.

It is provided with two relay outputs to control compressor and light. It is also provided with 3 NTC

probe inputs, one for temperature control, one to control the defrost end temperature of the evaporator

and the third to control condenser temperature or to display another temperature.

The HOT KEY output allows to connect the unit, by means of the external module XJ485-CX, to a

network line ModBUS-RTU compatible such as the dIXEL monitoring units of X-WEB family. It

allows to program the controller by means the HOT KEY programming keyboard.

The instrument is fully configurable through special parameters that can be easily programmed

through the keyboard.

3. Controlling loads

3.1 THE COMPRESSOR

The regulation is performed according to the temperature measured by the thermostat probe with a

positive differential from the set point: if the temperature increases and reaches set point plus

differential the compressor is started and then turned off when the temperature reaches the set point

value again.

In case of fault in the thermostat probe the start and stop of the compressor are timed through

parameters «COn» and «COF».

The relay of the second compressor is activated in parallel with the relay of the first compressor, with a

possible delay set in the AC1 parameter. Both the compressors are switched off at the same time.

3.2 FAST FREEZING

When defrost is not in progress, it can be activated by holding the «o» key pressed for about 3

seconds. The compressor operates to maintain the «ccS» set point for the time set through the «CCt»

parameter. The cycle can be terminated before the end of the set time using the same activation key

«o» for 3 seconds.

DEFROST

Defrost is performed through a simple stop of the compressor. Parameter «IdF» controls the interval

between defrost cycles, while its length is controlled by parameter «MdF».

3.3 DEFROST

Defrost is performed through a simple stop of the compressor. The parameters involved are: to control

the interval between defrost cycles (IdF), its maximum length (MdF) and two defrost modes: timed or

controlled by the evaporator’s probe (dFP and P3P). At the end of defrost dripping time is started, its

length is set in the FSt parameter. With FSt =0 the dripping time is disabled.

4. Relay 22-23 configuration- special functions

By means of the parameter oA3, it’s possible to configure the functions of the light relay (22-23), as

described in the following paragraphs:

OA3 = LIG: LIGHT RELAY (FACTORY SETTING)

By setting oA3 = Lig the relay will work as light relay, it is switched on and off by the light button on the

keyboard and is affected by status of the digital input when i1F = dor.

OA3 = CP2 2

COMPRESSOR MANAGEMENT

ND

By setting oA3 = cP2, the relay at terminals 22-23 will operate as «second compressor». It will be

activated in parallel with the relay of the first compressor, with a possible delay set in the AC1

parameter (seconds). Both the compressors are switched off at the same time.

—

AoP (cL; oP) Alarm relay polarity

OA3 = DB: NEUTRAL ZONE

By setting oA3 = db the controller will perform a

«neutral zone» regulation.

The heating element has to be connected to the

oA3 relay (22-23)

If the temperature increases and reaches set

point plus differential (+HY) the compressor is

started and then turned off when the

temperature reaches the set point value again.

If the temperature decreases and reaches the

set point minus differential( -HY) the oA3 output

(heater) is switched on and then turned OFF

when the temperature reaches again the set

point.

An additional parameter FSt provides the setting of temperature, detected by the evaporator probe,
above which the fans are always OFF. This is used to make sure circulation of air only if his
temperature is lower than set in FSt.
3.4.1 Forced activation for fans
This function, managed by the FCt parameter, is designed to avoid short cycles of fans, that could
happen when the controller is switched on or after a defrost, when the room air warms the evaporator.
If the difference between the evaporator temperature and the room temperature is higher than the FCt
value, the controller will activate the fans. This function is disabled if FCt=0.
3.4.2 Timed activation of the fans when the compressor is off.
When FnC=C-n or C-Y (fans in parallel to the compressor), the fans will be able to carry out on and off
cycles even if the compressor is switched off. The on and off interval of time follow the Fon and FoF
parameters. When the compressor is stopped the fans will go on working for the Fon time. On the
other side, with Fon=0 the fans will stay always off when the compressor is off.

CONTROLLING LOADS
3.1 THE COMPRESSOR
The regulation is performed according to the temperature measured by the thermostat probe with a
positive differential from the set point: if the temperature increases and reaches set point plus
differential the compressor is started and then turned off when the temperature reaches the set point
value again.
In case of fault in the thermostat probe the start and stop of the compressor are timed through
parameters Con and CoF.
The relay of the second compressor is activated in parallel with the relay of the first compressor, with a
possible delay set in the AC1 parameter. Both the compressors are switched off at the same time.
3.2 FAST FREEZING
When defrost is not in progress, it can be activated by holding the UP key pressed for about 3 sec.
The compressor operates to maintain the CCS set point for the time set through the CCt parameter.
The cycle can be terminated before the end of the set time using the same activation key UP for 3 sec.

KEYBOARDS
T620T
Two defrost modes are available through the tdF parameter: defrost through electrical heater (tdF =
EL) and hot gas defrost (tdF = in).
The defrost interval depends on the presence of the RTC (optional). If the RTC is present is controlled
by means of parameter EdF:
EdF=in: a defrost starts after elapsing the idF time (standard way for controller without RTC).
EdF=rtC: defrosts are scheduled by using a real time clock system, depending on the hours set in the
parameters Ld1..Ld6, during workdays, and in Sd1…Sd6 during holidays.
Other parameters are used to control defrost cycles: its maximum length (MdF) and two defrost
modes: timed or controlled by the evaporator’s probe (P2P).
At the end of defrost dripping time is started, its length is set in the Fdt parameter. With Fdt=0 the
dripping time is disabled.

9.1 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.
Alarm relay silencing (with oAx =ALr): (n; Y) n = silencing disabled: alarm relay stays
on till alarm condition lasts. Y = silencing enabled: alarm relay is switched OFF by
pressing a key during an alarm.
Third relay configuration (X60LT: terminals 1-3, XW60LRT: terminals 5-6): (dEF;
FAn; ALr; LiG; AUS; onF; db; dEF2; HES) dEF = defrost; FAn = do not select it; ALr =

First digital input polarity: (oP; CL) oP = the digital input is activated by opening the
contact; CL = the digital input is activated by closing the contact.
First digital input configuration: (EAL; bAL; PAL; dor; dEF; ES; AUS; Htr; FAn; HdF;
onF; Sbt) EAL = external alarm: “EA” message is displayed; bAL = serious alarm “CA”
message is displayed; PAL = pressure switch alarm, “CA” message is displayed; dor =
door switch function; dEF = activation of a defrost cycle; ES = energy saving; AUS =
auxiliary relay activation with oA2=AUS; Htr = type of inverting action (cooling or heating);
FAn = fan; HdF = Holiday defrost (enable only with RTC); onF = to switch the controller
off; Sbt = to activate Sabbath mode.
Digital input 1 alarm delay: (0 to 255 min) delay between the detection of the external
alarm condition and its signalling.
When i1F= PAL, it is the interval of time to calculate the number of pressure switch
activation.
Number of pressure switch activation: (0 to 15) Number of activation, during the did or
d2d interval, before signalling an alarm event (i1F, i2F=PAL).
If the nPS activation during did or d2d time is reached, switch off and on the instrument to
restart normal regulation.
Compressor status when open door: (no; FAn; CPr;F_C;) no = normal;
FAn = normal; CPr = compressor OFF, F_C = compressor OFF.
Outputs restart after door open alarm: (n; Y) n = outputs follow the odC parameter.
Y = outputs restart with a door open alarm.
Light off during Energy Saving status: n; Y.
Delta temperature during an Energy Saving cycle: (-30.0 to 30.0°C; -54 to 54°F) it
sets the increasing value of the set point [SET+HES] during the Energy Saving cycle.
9.4 PRESSURE SWITCH (I1F = PAL)
If during the interval time set by did parameter, the pressure switch has reached the number of
activation of the nPS parameter, the “CA” pressure alarm message will be displayed. The compressor
and the regulation are stopped. When the digital input is ON the compressor is always OFF. If the
nPS activation in the did time is reached, switch off and on the instrument to restart normal
regulation.
9.5 AUXILIARY OUTPUT SWITCHING (I1F =AUS)
With oA3=AUS and i1F=AUX it switches the fourth relay (22-23).
9.6 START DEFROST (I1F = DFR)
It starts a defrost if there are the right conditions. After the defrost is finished, the normal regulation will
restart only if the digital input is disabled otherwise the instrument will wait until the MdF safety time is
expired.
9.7 KIND OF ACTION: HEATING OR COOLING (I1F = HTR)
This function allows to invert the regulation of the controller: from cooling to heating and viceversa.
9.8 ENERGY SAVING (I1F = ES)
The Energy Saving function allows to change the set point value as the result of the SET+HES
(parameter) sum. This function is enabled until the digital input is activated.
