1. IMPORTANT USER INFORMATION
•The symbol is intended to alert the user of a non-insultated voltage source within the
product area that is sufficiently high to constitute a risk of electric shock to persons.
•The symbol is intended to alert the user of important operating and maintenance
(servicing) instructions.
•Dixell Srl reserves the right to modify this user’s manual at any time without prior notice. The
documentation can be downloaded from the Emerson website even prior to purchase.
•This manual is an integral part of the product and must always be kept near the device for easy
and quick reference. The product cannot be used as a safety device. Please read this manual
very carefully be sure you understand the information provided before using the device.
•Verify that the power supply voltage is correct before connecting the device. Do not expose it to
water or humidity: use the controller only within the operating limits, avoiding sudden temperature
changes and high atmospheric humidity in order to prevent condensation from forming.
Recommendations: disconnect all the electrical connections before performing any maintenance
task; insert the probe where it cannot be reached by the End User; the device must not be opened;
consider the maximum current that can be applied to each relay; make sure that the wires of the
probes, of the loads and the electical power supply cables are sufficiently separated from each
other, without crossing or intertwining. In case of applications in industrial environments, it may
be useful to use the main filters as well as the inductive loads.
•The customer shall bear full responsibility and risk for product configuration in order to achieve
the the final installation of the equipment/system. Upon the customer's request and following a
specific agreement, Dixell Srl may be present during the start-up of the final machine/application,
as a consultant, however, under no circumstances can the company be held responsible for the
correct operation of the final equipment/system.
•Since Dixell products are part of a high-level technology, a qualification and a
configuration/programming/commissioning stage is required to best use them. Otherwise, these
products may malfunction and Dixell cannot be held responsible. The product must not be used
in any way that differs from that stipulated in the documentation.
•The device must always be installed inside an electrical panel that can only be accessed by
authorised personnel. For safety purposes, the keyboard must be the only part that can be
reached.
•The electrical wiring connections must never be modify while the device is being used.

1592038420 XRB30-60-70-77CH EN v1.1 2021.09.15 XRB 5/38
•It is good practice to bear in mind the following indications for all Dixell products:
oPrevent the electronic circuits from getting wet as contact made with water, humidity or any
other type of liquid can damage them. Comply with the temperature and humidity limits
specified in the manual in order to store the product correctly.
oThe device must not be installed in particularly hot environments as high temperatures can
damage the electronic circuits and/or plastic components forming part of the casing. Comply
with the temperature and humidity limits specified in the manual in order to store the product
correctly.

component. Please contact qualified service personnel for any assistance.
oPrevent the device from being dropped, knocked or shaken as either can cause irreparable
damage.
oDo not clean the device with corrosive chemical products, solvents or aggressive detergents.
oThe device must not be used in applications that differ from that specified in the following
document.
•Separate the power supply of the device from the rest of the electrical devices connected
inside the electrical panel. The secondary of the transformer must never be connected to
the earth.
•Dixell Srl reserves the right to change the components of its products, even without notice,
ensuring the same and unchanged functionality.

After power-on, and when alarm icon is flashing:
-Insert the PROG-KEY into the HOT-KEY port.
-Keep DOWN button pressed for 3 sec.
-The FW update will start (the display will show the label “ΓΓΓ”).
At the end of the programming phase:
-The message “Err” is displayed in case of a failed FW update.
-The message “End” is displayed in case of successful FW update.
-Remove the PROG-KEY and press DOWN button to reboot the controller.
6.2 IMPORTANT NOTES
-PAY ATTENTION: this operation MUST be carried out only from expert personnel to avoid damaging
the controller. Please contact your regional reseller to have more information.
-Never switch off the controller during FW update.
-Disconnect all loads before updating the controller to avoid unpredictable output activations.
-After any FW UPDATE, the parameter maps must be updated.
7. PARAMETER TABLE
The controller has an internal memory where are stored a couple of complete parameter maps, normally
indicated as “nt”and “Lt”.
It will be possible to reload values for “nt”or “Lt”parameters map by using:

NOTES:
-“r.o.” stands for read only values
-Default factory settings here indicated are valid for XRB77CH and XRB70CH only
-Some parameters could not be present in other versions (for example XRB30CH) due to platform
specific limitations
-RTC parameters are present only in models equipped with RTC option.
9. REGULATION
The regulation is based on the temperature measured
by the thermostat probe (P1) with a positive differential
compared to the set point: if the temperature increases
and reaches the 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, thestart
and stop of the compressor are timed through
parameters CoF and Con.
10. ENERGY SAVING ALGORITHMS
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.
