Once you are in Exclusive mode, you will see parameters with CF (Configuration) tags. Do not touch tYPE (Probe type) unless you want your display to read "Probe Error."
Do not touch Adr (Modbus address) unless you are integrating with a BMS.
Use the Exclusive level to solve specific problems: adjusting the minimum allowed setpoint (LSE), maximum allowed setpoint (HSE), or analog output scaling. Then lock it back up immediately.
Resetting the password on your Eliwell SMP5500 controller can be straightforward if you follow these steps. Always ensure you document your passwords securely to avoid future access issues. If you encounter difficulties, consulting the user manual or contacting Eliwell's technical support can provide device-specific guidance.

programmable controllers. While specific "exclusive" password text for the SMP5500 is often proprietary to the installer, standard Eliwell systems utilize several common access procedures and default credentials. Eliwell France Access and Passwords Default User Password:
The standard password to access user-level parameters (often labeled ) is frequently for basic Eliwell controllers. Installer Password: Access to deeper configuration (often labeled
) typically requires a specific code provided in the technical manual or by the system integrator. Programming Menu:
On modules like the SMP55, the programming menu is accessed by pressing the keys simultaneously. Navigation Keys: : Increase or decrease values and navigate labels.
: Confirm values or move to the next menu level (folders, parameters). : Exit without saving or return to the previous level. Eliwell by Schneider Electric Proprietary Information Notice
Technical documentation for Eliwell Smart and Evolution systems often contains "Exclusive Property" disclaimers. This means the detailed programming structures and specific application passwords are the exclusive property of Eliwell Controls srl
and cannot be legally reproduced or divulged without authorization. Key Hardware Context DMI Interface: The SMP5500 typically serves as a Display Management Interface (DMI)

The Eliwell FREE Smart SMP5500 is a programmable controller typically used in HVAC and refrigeration applications. Accessing its protected menus, such as the Programming menus, often requires a specific password. Common Eliwell Default Passwords
While specific "exclusive" passwords can be set by individual manufacturers (OEMs), Eliwell devices traditionally use the following default codes: : The standard default for the (Installer) level on many Eliwell controllers.
: Often used as a default if no password has been explicitly configured. : A common fallback for various industrial controllers. Eliwell by Schneider Electric How to Access the Password Menu
To enter a password on models like the SMP5500, you generally follow these steps: Pfannenberg Press and hold the (or sometimes ) key for more than 5 seconds. arrow keys to scroll until you see the label (Installer Password). to enter the password field. eliwell+smp5500+password+exclusive

If the device is completely non-responsive, it may have a keypad lock engaged: Eliwell by Schneider Electric
: This parameter can be used to lock the keypad. When locked, you can view the "Machine Status" (like the setpoint) but cannot edit any settings.
: To disable the lock, you typically repeat the locking procedure within the parameter menu or hold a specific key combination (often simultaneously for several seconds).

programmable controller features a specialized security and customization architecture that distinguishes it from standard "fixed" controllers. While traditional controllers use static passwords, the
is part of a programmable platform where features—including password protection levels—are defined by the specific application uploaded to it. Exclusive Feature: Multi-Level Security Hierarchy One of the most powerful features of the
is its hierarchical access control. Unlike simpler units with a single lock, this controller typically supports multiple password levels to separate basic operation from critical system configuration:
User Level (PA1): Allows operators to access basic "User" parameters, such as viewing temperature probes or adjusting non-critical setpoints.
Installer/Service Level (PA2): This level is "exclusive" to technicians and provides access to the Full Parameter Map. By default, this is often set to a value like 15 in Eliwell systems, though it can be customized. Application Customization: Because the
is programmed via FREE Studio, developers can create custom passwords for specific machine functions, ensuring that proprietary algorithms and high-risk settings remain protected from unauthorized changes. Key Technical Specifications Eliwell SMP5500
is designed for versatility in HVAC/R and industrial automation:
Rich I/O Density: Features 5 Analogue Inputs (NTC/0-10V/4-20mA), 6 Digital Inputs, and a mix of 6 Digital/5 Analogue Outputs.
Modular Connectivity: Supports TTL, RS485, and LAN for connection to expansion modules or remote terminals like the SKP/SKW series.
Fast Commissioning: Compatible with the Multi-Function Key (MFK 100), allowing technicians to upload or download entire parameter maps and application software in seconds without a PC.
For the Eliwell SMP 5500 series (part of the FREE Smart family), managing access and "exclusive" configurations is handled through specific password levels and customer-defined parameters. Password Access Levels
Access to parameter settings on the SMP 5500 is restricted by two standard password levels to prevent unauthorized changes: Once you are in Exclusive mode, you will
Level 1 (User - PA1): Used to access basic user-level parameters. It is often not enabled by default (value 0).
Level 2 (Installer - PA2): 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
The "exclusive" feature likely refers to Client Code Parameters (e.g., CF60), which are specifically designed for the exclusive use of the customer or user.
Purpose: These allow installers or OEMs to assign unique values that identify the system type, reference, or specific configuration.
Confidentiality: Custom algorithms developed via the FREE Studio tool can be protected to ensure "confidentiality with appropriate security". How to Enter the Password To access these restricted features on the device:
Enter Programming Menu: Press and hold the Prg (or SET for 5+ seconds depending on your terminal).
Locate PA2: Use the arrow keys to scroll until the label PA2 (or PASS) appears.
Enter Code: Press SET, use the arrows to enter the code (try 22 or 15), and press SET again to confirm.
Navigate to Exclusive Parameters: Once inside, navigate to the CF (Configuration) folder to find client-specific "exclusive" parameters like CF60. SMP55 User Manual

The password system on Eliwell controllers typically uses two levels to protect settings from unauthorized changes:
PA1 (Level 1 - User): Provides access to basic user parameters. The default is often disabled (set to 0).
PA2 (Level 2 - Installer): Grants access to advanced configuration (installer) parameters. A common default installer password for many Eliwell units is 22. Before you start the reset process, ensure you

Are you trying to modify specific parameters like defrost cycles, or are you looking to reprogram the entire logic using the development software? IDPlus 978 - Eliwell
Before you start the reset process, ensure you have the following:
Topic Focus: Access level 3 (Exclusive/Manufacturer) password for the Eliwell SMP5500 controller.
Disclaimer: Passwords exist to prevent catastrophic system failure. Changing the wrong parameter (like tYPE or Adr) can physically destroy a compressor. Use this knowledge responsibly.
The most common "Exclusive" level password for the SMP5500 (specifically for firmware versions 3.x and higher) is:
1499
If that does not work, try 1411 or 1322 . These are legacy defaults that Eliwell engineers used during factory setup.
If none of those work: Someone has changed the default. You will need to perform a "FULL" factory reset via the hardware (which requires the Exclusive password to do normally... catch-22). In that case, call Eliwell technical support with the serial number of the unit; they can generate a master unlock code based on the MAC ID of the controller.
