•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.
2GENERAL DESCRIPTION
The XRB60CHC, 32x74x60mm format, is a microprocessor based controller suitable for applications
on medium or low temperature ventilated refrigeration units. It has 3 relay outputs to control
compressor, fans, light and defrost or auxiliary output. The device is also provided with up to 4 NTC
probe inputs: the first one for temperature control, the second one to be located onto the evaporator to
control the defrost termination temperature and to manage the fan and the third, optional and located
on the HOT-KEY port, used to control the condenser temperature. There is also a configurable digital
input. By using the HOT-KEY it is possible to program the instrument in a quick and easy way.
The controller has Bluetooth 4.2 connectivity.
3REGULATION
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 will
start. The compressor will stop when the
temperature reaches the set point value
again.
In case of fault because of the thermostat probe, the start and stop of the compressor are timed
through parameters CoF and Con.
4ENERGY REDUCTION ALGORITHM
4.1 DESCRIPTION
The device permits to set different temperature to be used during normal and reduced power use. The
standard SET-POINT (SET) is used to maintain the temperature at a certain value when the energy
saving status (ES) is not active. On the other side, when the ES status is active a different SET-POINT
(SET_ES), higher than the standard one, will be used. The parameter HES will have to be set to
change the regulation temperature according to the following formula:
SET_ES = SET + HES
There are also two different differential values for SET and SET_ES, which are used for compressor
cut-in and cut-out: when ES status is active the HYE parameter will be used instead of the HY
parameter.
The device uses special Energy reduction Algorithm (ErA algorithm from Dixell) to optimize loads
activation during the day. It is possible to set two different algorithms (ErA=bAS or Aut). They differ for
the used sensor and for the total length of the interval of time involved.
4.2 BASIC ENERGY SAVING ALGORITHM –ErA=bAS
This will be used when ErA=bAS. The energy saving status will be always saved in the internal
memory to resume previous operation if a power failure occurs. It needs the presence of a door switch
to work (i1F=dor).
4.2.1 Parameter involved and suggested values:
-ErA=bAS
-i1F=dor
-StE=4.0 hours
-EtS=6.0 hours
-HES=4.0 to 5.0 °C
-HYE=3 to 4°C
-dS=5 to 10 sec
-LdE=Y

mode
- Push the DOWN button for 3 sec (if enabled).
- Controller in ES mode for the EtS time.
- If the controller is in ES mode, it returns in Standard mode
(normal set-point) after opening the door more than dS time.
NOTE: the cycling mode (ES - Normal mode - ES - etc.) works if i1F=dor and EtS and StEare
different from zero. If EtS=0 or StE=0, the controller will not change the operating mode, and it will be
possible to change from the normal mode to the energy saving mode by using ES button or by setting
i1F=ES. See the below diagrams where the status changing is depicted:
4.3 AUTOMATIC ENERGY SAVING ALGORITHM
This will be used when ErA=Aut. The operations are controlled by using the Aid parameter. After
powering on the device, it automatically starts to analyze the temperature behavior by using the only
room temperature probe. In this way it can build the best energy saving model according to the
application. The device uses temperature behavior information of the previous Aid interval to manage
the loads during the current period. When Aid is set to use long periods (Aid>1), a day-by-day model
will be used during the first interval of time.
4.3.1 Parameter involved and suggested values:
-ErA=Aut
-HES= 3.0 to 5.0°C
-LdE=Y
-Aid=1 or 7
-nCE=4
-nCC=8
-Pdt=2
-HYE=3 to 4°C
-PPU=P1
-tun=depends on the regulation probe placement
NOTES:
1. In case of any blackout, the calculated energy saving model will be reset.
2. ErA can exclusively drive the light output by using the LdE parameter. When LdE=YES, the
light output status will change according to the energy saving (ES) status:
a. OFF if ES is active
b. ON if ES is not active
3. It is always possible to override the light output status by using the frontal button. Anyway, this
modification will have a temporary impact on the lights if LdE=YES. In fact, ErA will take the
control after the next ES status change.
4. ErA does not need any door switch input to work.
5. Be sure to place the room temperature probe in near the upper zone of the cabinet: this gives
the best results in terms of temperature variation analysis.
6. The Aid parameter indicates the interval of analysis as “number of days”. The suggested
values for it are 1 or 7, depending on the particular application.

XRB60CHC EN r1.1 2018.11.01.docx XRB60CHC 2/7
7. When Aid=1, the first day will be used to analyze the temperature behavior and to build the
model to apply to the second day. The model will be updated every day in order to better match
the working conditions.
8. When Aid=7, the first 7 days will be used to analyze the temperature behavior and to build the
model to apply to the next 7 days. The model will be updated every 7 days in order to better
match the working conditions.
9. When Aid=7, the first 7 days after power on will use a sub analysis base on 1-day model.
10. nCE is used to define the minimum duration of an energy saving interval of time
11. nCC is used to move the SET-POINT value from normal mode value to the energy saving
mode value by steps (1 step = 1°C or 1°F, starting from the SET value and increasing it every
30 min till reaching the SET_ES value)
12. Pdt is used to anticipate the end of the energy saving mode in order to decrease the
temperature of the bottles before starting the normal mode interval
13. PPU select the probe used for automatic energy saving algorithm
14. tun is used to change the sensibility of the automatic energy saving algorithm. tun=H (high) is
used for cabinet with regulation probe installed near the evaporator air outlet flow. tun=L (low)
is used for cabinet with regulation probe installed far away from the evaporator air outlet flow.
5EXTRA COOLING FUNCTION
The extra cooling function (named Pull Down) is active when the room temperature measured from the probe
1 goes over the SET+oHt+HYvalue. In this case, a special set-point value, lower than the normal SET value,
will be enabled. As soon as the room temperature reaches the SET+CCS value, the compressor will be
stopped and the normal regulation will restart. N.B.: pull down function is disabled when CCS=0 or CCt=0.
The CCt parameter sets the maximum activation time for any pull down. When CCt expires, the pull down will
be immediately stopped and the standard SET-POINT will be restored. NOTE: in case of energy saving mode
active, the used values will be: SET_ES=SET+HES, oHE and CCS.
6EVAPORATOR FANS
With FnC parameter it can be selected the fans functioning:
•FnC=C-n fans will switch ON and OFF with the compressor and not run during defrost; when
compressor is OFF, fans will enter a duty-cycle working mode (see FoF, Fon, FF1 and Fo1
parameters).
•FnC=o-n fans will run even if the compressor is off, and not run during defrost;
•FnC=C-Y fans will switch ON and OFF with the compressor and run during defrost; when
compressor is OFF all fans will enter a duty-cycle working mode (see FoF, Fon, FF1 and Fo1
parameters).
•FnC=o-Y fans will run continuously also during defrost.
After defrost, there is a timed fan delay allowing for drip time, set by means of the Fnd parameter.
An additional parameter FStprovides the setting of temperature, detected by the evaporator probe,
above which the fans are always OFF. By using this parameter it is possible to assure air circulation
only if air temperature is lower than FSt value.
6.1 EVAPORATOR FAN AND DIGITAL INPUT
When the digital input is configured as door switch (i1F=dor), fans and compressor status will depend on the
odC parameter value:
•odC=no normal regulation
•odC=FAn evaporator fan OFF
•odC=CPr compressor OFF
•odC=F-C compressor and evaporator fan OFF
When rrd=Y the regulation will restart after a door open alarm.
7DEFROST
7.1 DEFROST MODE
Any defrost operation can be controlled in the following way:
-EdF=rtC: by using an internal real time clock (only for models equipped with RTC).
-EdF=in: timed defrost, in this case a new defrost will start as soon as the idF timer elapses.
-EdF=Aut: automatic management, in this case the controller will start a new defrost any time a
change from normal to energy saving mode will occur (valid if ErA=Aut).
7.2 TIMED OR PROBE CONTROLLED MODE
Two defrost modes are available: timed or controlled by the evaporator’s probe. A couple of
parameters is used to control the interval between defrost cycles (idF) and its maximum length (MdF).
During the defrost cycle is possible to select some different display indications by using the dFd
parameter. These modes are available with any kind of defrost type:
-tdF=EL: electric heater defrost
-tdF=in: hot gas defrost.
7.3 AUTOMATIC DURATION DETECTION
When a defrost operation is performed by compressor stop (means by stopping the compressor and by
activating the internal ventilators), it will be possible to use an automatic defrost mode by setting od2=ALt. In
this case the device will use the evaporator probe (which MUST to be present and properly mounted on the
evaporator surface) to detect the end of the actual defrost phase. In any case, a maximum period of time
(MdF) and an upper evaporator temperature value will be used to stop the current defrost phase. If ErA=Aut,
the automatic defrost mode will activate a defrost at the beginning of any energy saving mode period. In this
case the idF delay is used as safety function. It forces the controller to activate a defrost operation when idF
runs. NOTE: during the defrost phase the loads (compressor and evaporator fans) will be controlled from the
defrost algorithm.

29x71 mm hole, and fixed using the special bracket supplied.
The temperature range allowed for correct operation is -20 to
60°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.
13 OPTIONAL FEATURES
The MDP/CX rear cover can be used to increase the protection
from water and dust.
The HOT-KEY is used for a quick and easy upload (from device
to HOT-KEY) or download (from HOT-KEY to device) of the
parameter map.
The BLU serial interface converts the TTL output into an RS485
signal that can be used to connect the unit to the controlling and
supervising system. Please note that standard version of this
converter does not work with XR-CHC devices.
14 ELECTRICAL CONNECTIONS
The instrument is provided with screw terminal block to connect cables with a cross section up to
2.5mm2. 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.
14.1 PROBES
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.
