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.

GENERAL DESCRIPTION
XR110C is connectable to the XJ500 monitoring system through the two terminals of serial
port RS485.
Model XR110C, 32 x 74 mm format, is a single stage temperature controller suitable for
applications in the field of refrigeration or heating. It’s provided with a relay output and a
PTC or NTC probe inputs configurable by the User.

CONTROLLING LOADS
3.1
TYPE OF REGULATION
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
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.
3.3
CH = HT: HEATING
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.
N.B. :In case of fault in the thermostat probe the start and stop of the compressor are
timed through parameters “COn” and “COF”.
4.
FRONT PANEL COMMANDS
:To display target set point; in programming mode it selects a parameter or
confirm an operation.
By holding it pressed for 5s the instrument Stand By started( If it is enable)
By holding it pressed for 3s when max or min temperature is displayed it will
be erased.
:To see the max. stored temperature; in programming mode it browses the
parameter codes or increases the displayed value. By holding it pressed for
3s the fast freezing cycle is started
:To see the min stored temperature; in programming mode it browses the
parameter codes or decreases the displayed value. By holding it pressed for
3s the auxiliary relay is switched ON or OFF ( If it is configured)
KEY COMBINATIONS:
+
To lock & unlock the keyboard.
+
To enter in programming mode.
+
To return to the room temperature display
