This is where "exclusive" configuration happens. Accessing this level requires navigating to the PASS menu. How to Enter the Password
Eliwell structures its controller menus hierarchically. Passwords act as gates to prevent end-users from accidentally changing core engineering variables.
However, modern custom-built systems (supermarkets, industrial plants) often have these default passwords disabled by the integrator. If you have ever typed 123 or 321 and received "Error" or a locked padlock icon, you need the override.

If the code is lost, a factory reset might be necessary. However, this will wipe all customized configuration data.
You tried -19 . You tried 321 . Nothing works. The screen still says "Loc" (Locked). Here is the exclusive troubleshooting guide:
Security & ethical considerations
The is a highly capable, programmable controller used extensively in commercial refrigeration, HVAC, and industrial climate control systems. Because these devices control critical parameters—like compressor cycles, defrost intervals, and multi-sensor configurations—unauthorized parameter modifications can result in stock spoilage, equipment failure, or voided commercial warranties.
By default, factory parameters often ship with standard numeric sequences (such as 00 , 11 , or 22 ), but these must be updated during commissioning to maintain system integrity. 🛠️ Accessing the Exclusive Parameter Menu
If the standard defaults ( 22 or 321 ) do not work, the OEM has changed the password. Passwords act as gates to prevent end-users from
