Регулирование выполняется согласно температуре, измеренной датчиком термостата с положительной разницей от уставки: если температура растет и достигает уставки плюс дифференциал, то компрессор запускается и затем выключается, когда температура снова достигнет значения уставки. При повреждении датчика термостата, пуск и остановка компрессора осуществляется по времени согласно параметров Cy и Cn.
Значение Hy автоматически вычитается из уставки. Если температура растет и достигает уставки минус дифференциал, то сработает выход и затем выключится, когда температура снова достигнет значения уставки.
Контроллеры должны монтироваться на вертикальной панели в вырез 29×71мм и закрепляться, используя поставляемые специальные держатели.

GENERAL WARNINGS
2.1
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.
Dixell Srl reserves the right to change the composition of its products, even without notice, ensuring
the same and unchanged functionality.
2.2
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.

GENERAL DESCRIPTION
Model XR01CX, format 32 x 74 x50 mm format is a single stage temperature controller suitable for
applications in the field of refrigeration or heating. It provides a relay output to drive the compressor. It is also
provided with 1 NTC probe input and one configurable digital input. The instrument is fully configurable
through special parameters that can be easily programmed through the keyboard or the by HOTKEY.
Model XR02CX, format 32 x 74 x 50 mm, is a digital thermostat with off cycle defrost designed for
refrigeration applications at normal temperature. It provides a relay output to drive the compressor. It is also
provided with 1 NTC probe input and one configurable digital input. The instrument is fully configurable
through special parameters that can be easily programmed through the keyboard or the by HOTKEY.

REGULATION
4.1
THE REGULATION OUTPUT
The regulation is performed according to the temperature measured by probe. The XR01CX is provided with
the CH programmable parameter wich enables the user to set the regulation both for heating or cooling
applications:
CH=cL —> cooling applications;
CH=Ht —> heating applications;
4.2
COOLING APPLICATIONS
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
«Cy» and «Cn».
4.3
HEATING APPLICATIONS ( ONLY FOR XR01CX)
The Hy value is automatically subtracted to
the SET POINT. If the temperature decreases
and reaches set point minus differential the
output is started and then turned off when the
temperature reaches set point value again.
1592020110 XR01-02CX GB r1.2 24.07.2015
5.
DEFROST (ONLY XR02CX)
Defrost is performed through a simple stop of the compressor. Parameter «id» controls the interval
between defrost cycles, while its length is controlled by parameter «Md».

Check connections before replacing the probe. Temperature alarms “HA” and “LA” automatically stop as soon as the temperature returns to normal values. Alarms “EA” and “CA” (with iF=EA or bA) recover as soon as the digital input is disabled.

Compressor and fans restarts Software release Parameter code table 7. DIGITAL INPUTS The free voltage digital input is programmable in different configurations by the “iF” parameter. EXTERNAL ALARM (iF=EA) As soon as the digital input is activated the unit will wait for “di” time delay before signalling the “EA” alarm message. The outputs status don’t change. The alarm stops just after the digital input is deactivated. SERIOUS ALARM (iF=bA) When the digital input is activated, the unit will wait for “di” delay before signalling the “CA” alarm message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is deactivated. DOOR SWITCH (iF=do) 13. CONNECTIONS 13.1 XR01CX – 24VAC/DC 13.2 XR01CX – 110VAC OR 230VAC It signals the door status and the corresponding relay output status through the “dC” parameter: no = normal (any change); Fn = Fan OFF; CP = Compressor OFF; FC = Compressor and fan OFF. Since the door is opened, after the delay time set through parameter “di”, the door alarm is enabled, the display shows the message “dA” and the regulation restarts if rd = y. 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. INVERSION OF THE KIND OF ACTION: HEATING - COOLING (iF=Hc) This function allows to invert the regulation of the controller: from cooling to heating and viceversa. 8. INSTALLATION AND MOUNTING Instrument XR01CX shall be mounted on vertical panel, in a 29x71 mm hole, and fixed using the special bracket supplied. The temperature range allowed for correct operation is 060 °C. Avoid places subject to strong vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to probes. Let air circulate by the cooling holes. 9. ELECTRICAL CONNECTIONS In case of model at 230Vac, connect power supply to terminals 6-7. Maximum current with faston is 16A The instrument is provided with fast on connectors. 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. 9.1 14. DEFAULT SETTING VALUES PROBES DESCRIPTION LABEL The probes 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. Place the defrost termination probe among the evaporator fins in the coldest place, where most ice is formed, far from heaters or from the warmest place during defrost, to prevent premature defrost termination. 0.1 ÷ 25°C/1 ÷ 45°F 10 °F Minimum Set Point -55°C÷SET/-67°F÷SET -40 °F Maximum Set Point SET÷150°C/ SET÷302°F 230 °F -12.0÷12.0°C/-21÷21°F 0 Differential 10.1 HOW TO PROGRAM THE HOT KEY FROM THE INSTRUMENT (UPLOAD) 1.
