Dixell XR60CX Settings Guide: Parameters, Defrost & Alarms

Dixell XR60CX Settings Guide: Parameters, Defrost & Alarms - Fast Fridgespares

The Dixell controller XR60CX is one of the most common temperature controllers on Australian coolrooms, freezer rooms and commercial fridges. It is also one of the most confusing the first time you open it up. The display shows a short code, the manual is a dense PDF, and a wrong change to one parameter can leave a freezer too warm or a defrost cycle that never ends.

This guide explains the XR60CX in plain English: what it controls, how to change the set point, how to open the Pr1 and Pr2 parameter menus, what each important parameter does, and what the alarm messages mean. Everything here about the XR60CX comes from the official Dixell (Emerson) manual, and we link to it so you can check any figure. We don't sell the XR60CX itself, but we do stock related controller parts, which are covered near the end.

Quick answer: hold SET and DOWN together for 3 seconds to open the user parameters (Pr1), then keep holding both for another 7 seconds to reach the hidden menu (Pr2). Hold SET for 2 seconds to change the set point. Hold DEF for 2 seconds to start a manual defrost. Write down every value before you change it.

What the Dixell XR60CX Controller Does

The XR60CX is a 32 x 74 mm digital controller made for medium and low temperature ventilated refrigeration, so cabinets and rooms that have an evaporator fan. It has three relay outputs: one for the compressor, one for the evaporator fan and one for defrost. It reads two temperature probes as standard, and a third probe or a digital input can be added.

Item What the manual says
Outputs Compressor relay, evaporator fan relay, defrost relay
Probe P1 Thermostat (cabinet or room) probe, used for temperature control
Probe P2 Evaporator probe, used to end defrost and manage the fan
Probe P3 (optional) Extra probe through the Hot Key socket, can raise a condenser temperature alarm or be shown on screen
Probe type NTC or PTC
Digital input Configurable, for example as a door switch, external alarm or defrost start
Supply versions 12 V, 24 V, 110 V or 230 V, depending on the model code
Defrost types Electric heater, or hot gas

The letters and numbers after XR60CX on the label (for example 5N0C1) show the exact build, including voltage and relay rating. Check the label on your own controller before you buy anything or change any wiring.

Dixell XR60CX vs XR20CX: What Is the Difference?

People often search for the Dixell controller XR20CX at the same time, because the two look alike. They are not the same job. The XR20CX is built for medium temperature systems that defrost by switching the compressor off, and it has a single compressor output. The XR60CX adds the fan and defrost relays, so it can run a heater defrost and manage an evaporator fan.

XR20CX XR60CX
Size (front) 32 x 74 mm 32 x 74 mm
Relay outputs One, for the compressor Three: compressor, fan and defrost
Probes P1 as standard, extras optional P1 and P2 as standard, P3 optional
Typical use Medium temperature, stop-defrost Medium or low temperature with a fan and defrost heater
Fan control No fan output Yes, with its own relay and fan parameters
Defrost method Stops the compressor to let the coil thaw Heater (or hot gas) defrost on its own relay

If your fridge has a defrost heater and an evaporator fan, you almost certainly need a controller with three outputs, not an XR20CX. When in doubt, send us a photo of the controller label and the wiring.

Keys and Lights on the XR60CX

Key What it does
SET Shows the set point. In programming mode it selects a parameter or confirms a value
DEF (hold 2 s) Starts a manual defrost
UP Shows the highest stored temperature. In programming it raises a value
DOWN Shows the lowest stored temperature. In programming it lowers a value
UP + DOWN (hold 3 s) Locks or unlocks the keyboard. The display shows POF when locked and Pon when unlocked
UP (hold 3 s) Starts or stops the continuous cycle
ON/OFF Switches the controller off, only if the onF parameter is set to oFF
Light Solid Flashing
Compressor Compressor on Waiting out the anti-short-cycle delay
Defrost Defrost running Drip time
Fan Fan on Fan delay after defrost
Alarm Alarm active -
°C / °F Showing the unit You are in programming mode

How to Change the Set Point

  1. Hold the SET key for more than 2 seconds. The set point and the °C/°F light start flashing.
  2. Press UP or DOWN within 10 seconds to change the value.
  3. Press SET again, or wait 10 seconds, to store it.

A short press of SET shows the current set point. The factory default is -5.0 °C, which will be wrong for most real jobs, so check it has been set for what you actually store.

How to Enter the Pr1 and Pr2 Parameter Menus

The XR60CX has two parameter levels. Pr1 holds the user settings that most people need. Pr2 is the hidden, full list.

Opening Pr1

  1. Hold SET and DOWN together for 3 seconds. The °C/°F light flashes.
  2. Use UP and DOWN to pick a parameter, then press SET to see its value.
  3. Change the value with UP and DOWN, then press SET to store it and move to the next parameter.
  4. Leave by holding SET and UP, or wait 15 seconds. The value is saved when it times out.

Opening Pr2

  1. Open Pr1 as above, then release the keys.
  2. Hold SET and DOWN again for more than 7 seconds. The Pr2 label appears, followed by the Hy parameter.
  3. Leave the same way, with SET and UP or a 15 second wait.

Before you change anything: photograph or write down every value you plan to touch. The manual we used describes how to save and reload settings with a Hot Key, but it does not describe a factory reset procedure. If a setting goes wrong and you don't have the old value, you will be guessing.

Dixell XR60CX Parameters Explained

The tables below cover the parameters people ask about most. The defaults are the factory values listed in the manual. A refrigeration installer may have changed them, so what you see on your controller can differ, and that is normal. Where a parameter is only in the hidden menu, the level column says Pr2.

Temperature control

Label What it does Default Level
Set The temperature you want the cabinet to hold -5.0 °C -
Hy Differential. The compressor starts at the set point plus Hy and stops at the set point 2.0 °C Pr1
LS / US Lowest and highest set point a user is allowed to enter -50 / 110 °C Pr2
Ot Calibration of the cabinet probe (P1), up to 12 °C either way 0.0 °C Pr1
OE Calibration of the evaporator probe (P2) 0.0 °C Pr2
P2P Is an evaporator probe fitted? If y, defrost ends by temperature, if n, by time y Pr1
COn / COF Compressor on and off times if the cabinet probe fails 15 / 30 min Pr2
CF Temperature unit, °C or °F °C Pr2
rES Display resolution. dE shows tenths of a degree, in shows whole degrees dE Pr1
Lod Which probe the display shows P1 Pr2

Defrost

Label What it does Default Level
tdF Defrost type. EL is an electric heater, in is hot gas EL Pr1
dFP Probe used to end defrost P2 Pr2
dtE Temperature at which defrost ends 8 °C Pr1
IdF Time between the start of one defrost and the next 6 h Pr1
MdF Longest a defrost can run. Also the fixed defrost time when there is no evaporator probe 30 min Pr1
dSd Delay before a defrost starts 0 min Pr2
dFd What the display shows during defrost it Pr2
dAd Longest display delay after defrost 30 min Pr2
Fdt Drip time after defrost, before the compressor restarts 0 min Pr2
dPo Defrost straight away on power-up (y) or wait for the interval (n) n Pr2

Defrost on the XR60CX works like this: every IdF hours the controller starts a defrost, the heater runs, and it stops when the evaporator probe reaches dtE or when MdF minutes have passed, whichever comes first. If frost keeps building up, those three settings are the first place to look, along with the heater itself. Our guide to a freezer not defrosting with ice build up shows how to test the parts, and the defrost heater testing guide covers the multimeter steps.

Evaporator fan

Label What it does Default Level
FnC Fan mode. C-n: fan runs with the compressor and stops in defrost. o-n: fan runs all the time and stops in defrost. C-Y and o-Y: the same, but the fan keeps running in defrost o-n Pr1
Fnd Fan delay after defrost 10 min Pr1
FSt Fan stops if the evaporator probe is above this temperature 2 °C Pr1
Fon / FoF Fan on and off times when the compressor is off 0 / 0 min Pr2
FAP Probe used for fan control P2 Pr2

Alarms

Label What it does Default Level
ALC Alarm type. Ab uses absolute temperatures, rE uses limits relative to the set point Ab Pr2
ALU High temperature alarm limit 110 °C Pr1
ALL Low temperature alarm limit -50 °C Pr1
AFH Differential for alarm and fan recovery 1 °C Pr2
ALd Delay before a temperature alarm sounds 15 min Pr2
dAO Alarm delay after power-up 1.3 Pr2

Notice that the factory high alarm is 110 °C and the low alarm is -50 °C, which means a brand new XR60CX will never raise a temperature alarm until you set sensible limits. If your HA message never appears even when the room is warm, check ALU first.

Digital input and door

Label What it does Default Level
i1P Digital input polarity. CL means activated by closing, oP by opening CL Pr1
i1F What the digital input does: door switch (dor), external alarm (EAL), serious alarm (bAL), pressure switch (PAL), start defrost (dEF) and others dor Pr1
did Delay before the door or alarm input acts 15 min Pr1
odc What stops when the door opens: nothing, fan, compressor, or both F_C Pr2

XR60CX Alarm and Display Messages

Message What it means What the controller does
P1 Cabinet probe fault Runs the compressor on a cycle set by COn and COF
P2 Evaporator probe fault Ends defrost on the timer
P3 Third probe fault Outputs stay as they are
HA High temperature alarm Outputs stay as they are
LA Low temperature alarm Outputs stay as they are
dA Door has been open too long Compressor and fans restart
EA External alarm Outputs stay as they are
CA Serious alarm or pressure switch All outputs switch off
POF / Pon Keyboard locked / unlocked -

Probe alarms clear on their own once the probe reads normally again, so check the wiring and connectors before you replace a probe. HA and LA clear when the temperature returns to normal. A pressure switch alarm (CA from the PAL setting) only clears when the controller is switched off and on again. If your display shows E0 or E1 instead, check the brand on the front, because it may be a Carel or another make. See the next section.

Using a Different Controller? Start Here

Not every fridge uses a Dixell. Carel and Elitech controllers show different codes, and the same message can mean something else. If you're chasing a Carel controller E1 error, a Bromic fridge not cooling, or even a Skope fridge light not working, our commercial fridge error codes guide goes through each one.

Replacing or Mounting a Dixell XR60CX

If your controller has failed, check these before you order a replacement: the supply voltage on the label, the compressor relay rating (the manual lists 8, 16 and 20 amp versions), whether it uses NTC or PTC probes, and the size of the panel opening. Controllers hold your settings, so write them down first and copy them across.

We don't list the XR60CX at the moment, but these related parts are in stock:

Browse more in our refrigeration temperature controllers and commercial fridge parts, or send your controller label to the Find Your Part page.

Safety: the XR60CX and the equipment around it run on mains voltage. Isolate the power before you open anything. Controller wiring and relay changes should be done by a licensed electrician or refrigeration mechanic, and any refrigerant work needs an ARC licensed technician.

Frequently Asked Questions

What is a Dixell controller XR60CX?

It's a digital temperature controller for medium and low temperature ventilated refrigeration. It has three relays (compressor, fan and defrost), two temperature probes as standard and a configurable digital input.

What is the difference between the Dixell XR20CX and XR60CX?

The XR20CX has one compressor output and suits medium temperature systems that defrost by stopping the compressor. The XR60CX adds fan and defrost relays, so it can run a heater defrost and control an evaporator fan.

How do I enter the parameters on a Dixell XR60CX?

Hold SET and DOWN for 3 seconds to open the Pr1 menu. To reach the hidden Pr2 menu, release the keys and hold SET and DOWN again for more than 7 seconds.

What is the default set point on a Dixell XR60CX?

The factory set point in the manual is -5.0 °C. Most installations change it to suit the product being stored.

How do I start a manual defrost on the XR60CX?

Hold the DEF key for more than 2 seconds.

How do I lock or unlock the XR60CX keyboard?

Hold UP and DOWN together for more than 3 seconds. The display shows POF when locked and Pon when unlocked.

What does P1 mean on a Dixell XR60CX?

P1 is the cabinet probe alarm. The controller can't read the thermostat probe, so it runs the compressor on a fixed on and off cycle until the probe works again. Check the wiring first, then test the probe.

Where can I find the Dixell controller manual XR60CX?

The official manual is published by Dixell (Emerson). We link to it at the end of this guide. Always use the manual that matches the model code on your controller label.

Need Help With a Commercial Fridge Controller?

Settings are only half the job. If the display shows an error or the cabinet won't hold temperature, check the probe, fans and defrost parts as well. Send your controller model and a photo of the label to sales@fastfridgespares.com.au or call 0405 972 558 and we will help you find the right part.
