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.p.A.” (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 XR10C, format 32 x 74 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 2 NTC or PTC probe inputs, the first one for temperature
control, the second one, optional, to connect to the HOT KEY terminals to signal the
condenser temperature alarm or to display a temperature. The digital input can operate as
third temperature probe.
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 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.

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.

4. FRONT PANEL COMMANDS
: To display target set point; in programming mode it selects a parameter or confirm
an operation.
(DEF) Not enabled
(UP): To see the max. stored temperature; in programming mode it browses the
parameter codes or increases the displayed value.
(DOWN) To see the min stored temperature; in programming mode it browses the
parameter codes or decreases the displayed value.
To switch the instrument off, if onF = oFF.
Not enabled
KEY COMBINATIONS:
+
To lock & unlock the keyboard.
+ To enter in programming mode.
+ To return to the room temperature display.
4.1 USE OF LEDS
Each LED function is described in the following table.

5. MAX & MIN TEMPERATURE MEMORIZATION
5.1 HOW TO SEE THE MIN TEMPERATURE
1. Press and release the n key.
2. The “Lo” message will be displayed followed by the minimum temperature recorded.
3. By pressing the n key again or by waiting 5s the normal display will be restored.
5.2 HOW TO SEE THE MAX TEMPERATURE
1. Press and release the o key.
2. The “Hi” message will be displayed followed by the maximum temperature recorded.
3. By pressing the o key again or by waiting 5s the normal display will be restored.
5.3 HOW TO RESET THE MAX AND MIN TEMPERATURE RECORDED
1. Hold press the SET key for more than 3s, while the max. or min temperature is
displayed. (rSt message will be displayed)
2. To confirm the operation the “rSt” message starts blinking and the normal temperature
will be displayed.
