1. GENERAL WARNING
1.1 PLEASE READ BEFORE USING THIS MANUAL
•This manual is part of the product and should be kept near the instrument for easy and quick
reference.
•The instrument shall not be used for purposes different from those described hereunder. It cannot
be used as a safety device.
•Check the application limits before proceeding.
1.2 SAFETY PRECAUTIONS
•Check the supply voltage is correct before connecting the instrument.
•Do not expose to water or moisture: use the controller only within the operating limits avoiding
sudden temperature changes with high atmospheric humidity to prevent formation of
condensation
•Warning: disconnect all electrical connections before any kind of maintenance.
•Fit the probe where it is not accessible by the End User. The instrument must not be opened.
•In case of failure or faulty operation send the instrument back to the distributor or to “Dixell S.r.l.”
(see address) with a detailed description of the fault.
•Consider the maximum current which can be applied to each relay (see Technical Data).
•Ensure that the wires for probes, loads and the power supply are separated and far enough from
each other, without crossing or intertwining.
•In case of applications in industrial environments, the use of mains filters (our mod. FT1) in
parallel with inductive loads could be useful.
2. GENERAL DESCRIPTION
Model XW10L, 38x185 mm format, and model XW10V, 100x64 format, are microprocessor based
controllers suitable for applications in the field of refrigeration or heating. They are provided with 2 relay
outputs one for the regulation and other one for the lights. They are also provided with 1 NTC or PTC
probe input for temperature control. There is 1 digital input (free contact) configurable by parameter.
An output allows the user to programme the parameter list with the “Hot Key”.
3. CONTROLLING LOADS
3.1 THE REGULATION OUTPUT
The regulation is performed according to the temperature measured by the probe.
The instruments are provided with the CH programmable parameter which enables the user to set the
regulation both for heating or cooling applications:
· CH = CL: cooling applications
· CH = Ht: heating applications
3.2 CH = CL: COOLING APPLICATIONS.
The Hy value is automatically set above 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”.
3.3 CH = HT: HEATING APPLICATION.
The Hy value is automatically set under the Set Point. If the temperature decreases and reaches set
point minus differential the regulation output is activated and then turned off when the temperature
reaches the set point value again.
3.4 FAST COOLING
It can be activated the keypad by holding the okey pressed for about 3 seconds. The compressor
operates in continuous mode 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, ofor about 3 seconds.
4. KEYBOARD

rES Resolution (for °C): (in = 1°C; de = 0,1°C) allows decimal point display.
dE = 0,1°C; in = 1 °C
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

temperature alarm condition after closing the door.
doA Open door alarm delay:(0÷255 min) delay between the detection of the open door condition and
its alarm signalling: the flashing message “dA” is displayed.

6. DIGITAL INPUTS
The XW10L has 1 free contact digital input. It is programmable in six different configurations by the
“I2F” parameter.
6.1 DOOR SWITCH INPUT (I2F = dor)
It signals the door status and the corresponding relay output status through the “odc” parameter:
no, Fan = normal (any change);
CPr, F_C = Compressor OFF;
Since the door is opened, after the delay time set through parameter “dOA”, the alarm output is
enabled and the display shows the message “dA”. The alarm stops as soon as the external digital input
is disabled again. During this time and then for the delay “dot” after closing the door, the high and low
temperature alarms are disabled.
6.2 GENERIC ALARM (I2F = EAL)
As soon as the digital input is activated the unit will wait for “did” time delay before signalling the “EAL”
alarm message. The outputs status don’t change. The alarm stops just after the digital input is de-
activated.
6.3 SERIOUS ALARM MODE (I2F = BAL)
When the digital input is activated, the unit will wait for “did” delay before signalling the “BAL” alarm
message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de-
activated.
6.4 PRESSURE SWITCH (I2F = PAL)
If during the interval time set by “did” parameter, the pressure switch has reached the number of
activation of the “nPS” parameter, the “PAL” 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 are reached, switch off and on the instrument to restart
normal regulation.
6.5 ENERGY SAVING (I2F = ES)
The Energy Saving function allows to change the set point value as the result of the SET+ HES
(parmeter) sum. This function is enabled until the digital input is activated.
6.6 REMOTE ON/OFF (I2F = ONF)
This function allows to switch ON and OFF the instrument.

CL : the digital input is activated by closing the contact.
OP : the digital input is activated by opening the contact
7. INSTALLATION AND MOUNTING

8. ELECTRICAL CONNECTIONS
The instruments are provided with screw terminal block to connect cables with a cross section up to 2,5
mm2 for the digital and 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.
8.1 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..
9. 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.
9.1 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.
2. Automatically the parameter list of the “Hot Key” is downloaded into the Wing memory, the
“DoL” message is blinking. After 10 seconds the instrument will restart working with the new
parameters.
3. Turn OFF the instrument remove the “Hot Key”, plug in the TTL serial cable, then turn it ON
again.
At the end of the data transfer phase the instrument displays the following messages:
“end “ for right programming. The instrument starts regularly with the new programming.
“err” for failed programming. In this case turn the unit off and then on if you want to restart the
download again or remove the “Hot key” to abort the operation.
9.2 UPLOAD (FROM THE INSTRUMENT TO THE “HOT KEY”)
1. Turn OFF the instrument by means of the ON/OFF key and remove the TTL serial cable if
present; then turn it ON again.
2. When the Wing unit is ON, insert the “Hot key” and push okey; the "uPL" message
appears.
3. Push “SET” key to start the UPLOAD; the “uPL” message is blinking.
4. Turn OFF the instrument remove the “Hot Key”, plug in the TTL serial cable, then turn it ON
again.
At the end of the data transfer phase the instrument displays the following messages:
“end “ for right programming.
“err” for failed programming. In this case push “SET” key if you want to restart the programming again
or remove the not programmed “Hot key”.
