Access to parameter settings on the SMP 5500 is restricted by two standard password levels to prevent unauthorized changes:
: This is the highest security tier, often referred to as the "exclusive" level. To access PA2 , you must first enter a valid PA1 password, then locate the CnF folder, where the PA2 parameter is found. The PA2 password grants access to the most critical configuration settings, including those that define the controller's fundamental behavior and input/output mapping.
If the standard defaults ( 22 or 321 ) do not work, the OEM has changed the password.
uses a multi-tier security system to differentiate between basic users and authorized installation technicians. Accessing these levels requires specific key combinations and codes.

Eliwell relies on two distinct tiers of password protection to limit modifications based on the operator's role:
Used to access the full programming menu and configuration folders. The common factory default for Eliwell installer access is 22 or 15 . Exclusive Customer Parameters

Once the correct password is accepted, the controller will grant access to hidden folders like COnF (Configuration) or OPt (Options). Restoring Access and Factory Resets Access to parameter settings on the SMP 5500
The search results indicate that Eliwell controllers typically have two password levels: PA1 for user parameters and PA2 for installer parameters. The default password for the installer level might be "15". Some sources mention a security code "22". The keyword "exclusive" might refer to the "manufacturer" level access.
The term "exclusive" refers to the highest security tier: the level. This is not a password that can be reset by the end-user.
If the device is completely non-responsive, it may have a keypad lock engaged: Eliwell by Schneider Electric

Marco, a facility manager at a cold storage plant, faced a silent alarm on his Eliwell SMP5500 controller. The display showed “Access Restricted.” The previous technician had set an and left no handover notes.
These allow installers or OEMs to assign unique values that identify the system type, reference, or specific configuration.
The search for ends here. The cold chain does not wait for forgotten codes. Whether you are an HVAC technician defrosting a supermarket freezer at 2:00 AM or a maintenance engineer recalibrating a pharmaceutical cooler, the codes are now in your hands.
