Dixell XW264K and XW60VS

Cool room controllers with alarm codes spelled out (EAL, bAL, PAL) and a password on the full parameter list. XW264K has six relays and two defrost probes; XW60VS has three relays.

What it is: Cool room controller with password-protected Pr2. Covers XW264K (two evaporators, remote T620/V620 keypad) and XW60VS (100×64 mm panel unit).

Key combo: Hold SET + DOWN for a few seconds for Pr1. Pick Pr2 and enter the service password for the full list.

Dixell XW264K and XW60VS error codes

Code	Meaning	Likely cause	How to reset
P1	Thermostat probe fault	Probe open, shorted, unplugged or wrong type (PbC)	Clears by itself a few seconds after the probe reads normally. Check wiring and PbC before replacing the probe. Alarm relay on; compressor cycles on the COn / COF times.
P2	Evaporator probe fault (XW60VS) / first evaporator probe	Probe open, shorted, unplugged or wrong type (PbC)	Clears by itself a few seconds after the probe reads normally. Check wiring and PbC before replacing the probe. Alarm relay on; defrost ends on time.
P3	Third probe fault (second evaporator on XW264K, display probe on XW60VS)	Probe open, shorted, unplugged or wrong type (PbC)	Clears by itself a few seconds after the probe reads normally. Check wiring and PbC before replacing the probe. Alarm relay on; other outputs unchanged.
HA	High temperature alarm	Room above ALU for longer than ALd	Alarm relay on. Clears when back inside the limit.
LA	Low temperature alarm	Room below ALL for longer than ALd	Alarm relay on. Clears when back inside the limit.
EE	Memory fault	Internal data check failed	Press any key to reset. If it returns, replace the controller.
dA	Door alarm (XW60VS) / defrost time-out (XW264K)	XW60VS: door open too long. XW264K: defrost ended on time, not temperature	XW60VS: clears when the door shuts. XW264K: check defrost heaters and probe.
EAL	External alarm	Digital input active	Alarm relay on. Clears when the input resets.
bAL	Serious external alarm	Digital input active	All other outputs off. Clears when the input resets.
PAL	Pressure switch alarm	Pressure switch tripped too often within did	All other outputs off. Power off and on to reset.

How to enter service / parameter mode

Hold SET + DOWN for a few seconds. The first Pr1 parameter shows.
Scroll to Pr2 and press SET. PAS flashes, then 0 - - with the first digit flashing.
Enter the service password one digit at a time with UP / DOWN, pressing SET after each digit.
With the right password the full parameter list opens.

How to change and save a setting

Scroll with UP or DOWN to the parameter code.
Press SET to show its value.
Change it with UP or DOWN.
Press SET to store it and move to the next parameter.
To leave, press SET + UP or wait about 15 seconds. Values are kept either way.

Other useful key presses

Task	How
Manual defrost	Hold the defrost key for 3 s.
Fast freeze	Hold UP for 3 s.
Move a parameter into Pr1	In Pr2, press SET + DOWN on it. A lit decimal point means it is in Pr1.

Notes

tdF on these models: rE = electric heater, rT = thermostatic electric defrost, in = hot gas.
Defaults differ between the two models where shown. Check the unit before relying on them.

For licensed technicians only. This equipment can involve mains voltage, high-voltage microwave circuits, gas and refrigerant. Isolate power (and gas) before opening panels, follow the manufacturer's manual and your local licensing rules (for example ARC refrigerant handling and electrical or gas licences). Wrong settings can spoil food or damage equipment. Check every value on the unit in front of you before changing it.
