Elitech ECS-06CX error codes

Code	Meaning	Likely cause	How to reset
P1	Cabinet probe fault	Probe open or shorted	Automatic once fixed. Compressor runs on Cy / Cn. Cy = 0 keeps it off; Cn = 0 with Cy above 0 keeps it on.
P2	Evaporator probe fault	Probe open or shorted	Automatic. Defrost runs on id and Md.
HA	High temperature alarm	Cabinet above AU after Ad and dA	Clears below AU. Outputs unchanged.
LA	Low temperature alarm	Cabinet below AL after Ad and dA	Clears above AL. Outputs unchanged.
nP	No evaporator probe	Evaporator reading requested with P2 = n	Information only.
Er	Copy card failed	Bad contact or card	Reseat and repeat.
EP	Copy card does not match	Card holds data from another model	Use the right card or upload to it first.
rst	Reset done	Parameters reloaded from the copy card values	Information only.
oF / on	Keypad locked / unlocked	Light + rotate keys held 3 s	Hold both 3 s again.

How to enter service / parameter mode

Hold Set + rotate (down) for 3 seconds. The set light comes on (Pr1, user list).
For every parameter keep holding to 7 s until L2 shows, then release: Hy appears (Pr2). If Pr1 is empty, nP shows first; keep holding.

How to change and save a setting

Pick a code with light (up) or rotate (down) and press Set.
Change with the same keys.
Press Set to store and move on.
Press Set + light, or wait 15 s, to save and exit.

Other useful key presses

Task	How
Change set point	Hold Set 2 s, adjust, press Set
Show evaporator temperature	Tap the defrost (Rst) key
Manual defrost	Hold the defrost key 2 s
Reset to copy-card values	Hold Set + light 3 s until rst shows
Upload to copy card	Insert the card, hold light until uP, wait 3 s, remove, power-cycle
Download from copy card	Insert the card, hold rotate until do, wait 3 s, remove, power-cycle
Move a parameter Pr2 ↔ Pr1	In Pr2 press Set + rotate on it. Decimal point off = now in Pr1

Notes

Hot gas mode (td = in): compressor runs and the four-way valve output is on during defrost.
Fans stop whenever the evaporator is warmer than FS (with P2 = y).

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.
