Dixell™ Universal-XR Controller
The Only Replacement Controller You’ll Ever Need
Simplify repair of refrigeration and heating controllers

rom reach-in coolers to deli prep
tables to bread proofers, the
F
foodservice industry uses literally
thousands of different refrigeration and
heating units. It simply isn’t practical for
contractors and wholesalers to keep every
possible controller model on hand. But when
a controller fails, waiting on a specific
replacement can cause costly delays for
both the repair service and the customer.
Emerson responded to this common
problem by creating the Dixell™ UniversalXR controller. This dual-supply voltage
controller is capable of replacing thousands of SKUs, including more than 150
of the most common 32x74 mm format
controllers. The most typical applications
can be back up and running quickly —
often in just a few minutes — regardless of
the original make or manufacturer.
The Universal-XR controller is a boon
to repair contractors. The unit is stocked
at thousands of authorized Emerson
wholesalers nationwide, usually at a very
competitive cost compared to the controllers it can replace. With Universal-XR
units on their trucks, contractors won’t
have to waste as much time selecting a
specific controller. This saves time for
themselves and eliminates downtime for
their customers, enabling contractors to
get to their next jobs quicker.
Wholesalers also stand to benefit from
our controller. The unit can significantly
reduce the number of SKUs they need to
keep in stock. They can keep inventories
lower — yet still have the right controller
for the job available.
Key benefits of the Universal-XR
controller
Quick installation and programming —
The Universal-XR controller gives repair
contractors a “drop-in” solution that can
be configured rapidly in just three simple
steps (see “Rapid setup in three simple
steps” sidebar).
• Dimensional footprint matches more
than 80 percent of the most common
controllers on the market.
• Simple wiring setup supports four to
eight connections.
• Hot key enables fast and simple
programming.
Rapid setup in three simple steps
Dual-voltage power supply — The unit is
versatile enough to replace commonly
used low- and high-voltage controllers.
• Two different terminal blocks give
direct connections to 12VAC/DC or
230VAC power supplies. One unit
covers both standard voltages.
• Power supply isn’t needed to change
voltage in 230VAC configurations.
• 12VAC/DC configurations typically
don’t need an electrician to sign off
on the installation.
“Plug and play” functionality — Dixell’s
common five-pin connector, which is
similar to a USB device, enables a wide
variety of useful applications, including:
• Easy connectivity for downloading
parameters, fault history logs and
other data.
Seven pre-configured applications —
Support quick and easy startup. (See
the “Save time with pre-configured
applications” sidebar.)
• Seven different maps are selectable
from the intuitive interface, allowing
the most common applications to be
set up in just a few minutes.
• Automatically configure up to three
probes, four relays and two digital
inputs.
Self-learning automatic probe detection —
Other controllers are typically limited to
just one type of sensor: NTC or PTC. The
Universal-XR controller automatically
detects which type of sensor is in use and
configures itself appropriately.
• Single controller can manage both
common types of probes.
• One-touch smart sensing: just press
a single button for three seconds and
wait for the controller to detect the
probes.
• Contractors don’t have to worry that
the controller won’t work because of a
sensor mismatch or faulty reading.
• Enables custom parameters to be
uploaded into the controller.
• Factory reset to default configuration.
• Offers CTL serial connections.
• Allows connections to the cloud
or BMS, including the Emerson
XWEB300D and XWEB500D EVO
web servers for control and alarm
management.
Complete system management — The
controller manages every aspect of the
cooling or heating system.
• Activates and deactivates the compressor,
defroster, fan and motors.
• Senses the difference between readings
caused by the controlled devices versus
issues with wiring.
Simple two-zone/twin evaporator defrost
support — Two evaporator probes and
specific parameters allow the unit to easily
control two different defrost terminations.
• The display alternates between the
temperatures of each zone.
• Users can monitor two zones (e.g.,
produce and ice cream) at a glance.
User-friendly front display — Easily
allows users to see what’s going on in
the system.
• Intuitive design enables customers
to see and understand compressor,
defroster, fan and motor activities in
a single glance.
Save time with pre-configured applications
Many typical jobs can be set up in minutes simply by selecting one of seven
pre-configured applications from the easy-to-use interface. Choosing the
controller that best fits the required application will automatically adjust all
relevant settings.
Pre-programmed applications include:
1. On/Off Thermostat (cooling)
2. Thermostat With Off-cycle Defrost (timed)
3. Thermostat With Electric/Hot Gas Defrost, Time Initiated/Time
Terminated
4. Thermostat With Electric/Hot Gas Defrost, Time Initiated/Temperature
Terminated
• Popular with many users.
By providing easy service replacement for
most major controllers, the Universal-XR
controller offers an instant replacement
solution for nearly every application.
Why keep trying to manage more than
150 separate products when a single
controller can take their place?
5. Thermostat With Electric/Hot Gas Defrost, Time Initiated/Temperature
Terminated Plus Evaporator Fan Delay
6. Thermostat for Twin Evaporator Defrost Applications
7. On/Off Thermostat (heating)
