Eliwell SMP5500 (often referenced as part of the series) is a programmable controller used in HVAC/R applications. Accessing protected parameters requires specific password levels to prevent unauthorized changes to critical system configurations. Password Access Levels

Eliwell controllers typically use a tiered password system. While specific "exclusive" passwords can be customized by OEMs (Original Equipment Manufacturers), the standard access levels are: User Level (Level 1):

Generally no password is required for basic setpoint adjustments. Installer/Service Level (Level 2): Requires a password (factory default is often Manufacturer/Exclusive Level (Level 3):

This is a restricted level often locked by the machine manufacturer. There is no universal "exclusive" password as it is set during the programming phase. How to Enter the Password

To access restricted menus and enter the password on an SMP5500 interface: Enter the Menu: Press and hold the ) key for more than 5 seconds. Locate "PA2":

(part of the FREE Smart series), you typically need specific installer or manufacturer passwords. 🔑 Common Default Passwords

Installer Level (Level 1): 54 is a standard password for entering the PASS folder to unlock protected parameters.

Alternative Installer Code: 22 is often used in Eliwell-based thermostats for full menu access. User Level: 0 (Disabled by default).

Manufacturer Level: This varies by application but is sometimes referred to as Ui28 in technical manuals. 🛠️ How to Enter the Password

According to the SMP55 User Manual, follow these steps to unlock the controller:

Enter Programming: From the main display, press the ESC and SET keys simultaneously to enter the PAr (Parameters) menu.

Find the PASS Folder: Use the UP and DOWN arrows to scroll until the display shows the PASS label. Input the Code: Press SET to enter the folder.

Use the UP arrow to change the value to 54 (or 22 depending on your specific firmware).

Confirm: Press SET to save. The display will return to the main parameter folders (e.g., COnF, OPt), now with "exclusive" or restricted parameters visible. ⚠️ Troubleshooting Access

Visibility Levels: Parameters are often tagged with visibility values: 0 (hidden), 1 (installation level), or 2 (manufacturer level). If a parameter remains hidden after entering 54, it may require a higher-tier manufacturer code.

Resetting: If the default codes don't work, the password may have been changed manually. Check for a PS2 parameter in the diS folder to view or modify the current password.

💡 Pro Tip: Always power-cycle the device after making major configuration changes to ensure they are properly initialized. If you'd like to troubleshoot a specific setting:

Getting exclusive access to the Eliwell SMP5500 (part of the FREE Smart series) is a standard procedure for HVAC technicians and system integrators who need to modify critical system configurations. This programmable controller is designed for high-performance applications, meaning many of its deeper settings are password-protected to prevent accidental or unauthorized changes. Accessing Protected Menus

The SMP5500 uses a tiered security system to separate daily operation from deep technical configuration.

Level 1 (User Level): Provides access to basic status variables and alarms.

Level 2 (Installer/Technical Level): This is where "exclusive" configuration happens. Accessing this level requires navigating to the PASS menu. How to Enter the Password

To access the restricted PAr (Parameters) or COnF (Configuration) folders:

Open the Menu: From the main view, press and hold the set and esc buttons simultaneously (or press Prg depending on the specific firmware version).

Locate PASS: Use the UP or DOWN arrows until the label PASS appears on the display.

Enter the Code: Press set to enter the password sub-menu. Use the arrows to select the numeric code and confirm with set.

Confirm Access: If the code is correct, the device will unlock the hidden parameter folders, such as COnF and OPt. Default Password Values

While many systems are customized by the OEM (Original Equipment Manufacturer), Eliwell controllers often ship with standard default passwords unless modified by the installer:

Common Installer Password: 22 is a frequent default for many Eliwell parameter levels.

Alternative Default: 15 is often used in related Eliwell IDPlus or EWPlus models and may be tried if 22 does not work.

Custom Codes: Many technicians set a custom code between 0 and 255 via the UI27 parameter to ensure exclusive site access. Managing Exclusive Parameters

Once inside the exclusive menu, you can manage specific "Client Codes" and "Installation Passwords":

Parameter UI27: Defines the password required for Level 1 or standard installer access.

Client Codes (CF60/CF61): These are often used for exclusive tracking, allowing the customer to assign unique values that identify specific system models or configurations.

Programming Software: For full control without using the keypad, the Eliwell FREE Studio software suite allows for the creation of custom password-protected menus and high-level logic development. Eliwell SMP5500 Controller : Make sure you are

Warning: What NOT to touch

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.

Preparation

Before you start the reset process, ensure you have the following:

  1. Eliwell SMP5500 Controller: Make sure you are working with this specific model.
  2. Access to the Device: Physical access to the controller is necessary.
  3. Basic Technical Knowledge: Understanding basic electronics and navigation through menu settings is helpful.

Part 8: The Future – Software-Based Exclusive Access

Eliwell’s latest firmware (v3.5+) now requires a dynamic exclusive password generated by the Eliwell Keygen Tool (available only to authorized service centers). However, for the legacy SMP5500 (the most common unit on the market), the static exclusive password -19 remains the golden ticket.

If you are integrating the SMP5500 into a modern IoT BMS (Building Management System), ensure your SCADA software has the exclusive password saved in its Modbus polling configuration. Without it, you cannot write to holding registers 40001-40050.

2. What Does “Password Exclusive” Mean Here?

Unlike a simple admin password, the “Exclusive” password on the SMP5500 unlocks hidden engineering parameters. These are NOT listed in the standard user or installer manuals. They include:

  • Factory calibration offsets (sensors, inputs)
  • OEM-specific configuration locks
  • Hidden PID loops
  • Custom I/O pin mapping
  • Advanced communication settings (Modbus, serial protocols)

Why is it called exclusive? Because Eliwell (now part of Schneider Electric) originally intended this level only for OEM manufacturers who integrate the controller into their own equipment (e.g., a fridge brand like True, Foster, or ARneg). The end user or even a field tech is not supposed to touch these.

The Master Unlock Sequence

For the vast majority of SMP5500 units manufactured after 2018, the exclusive Level 3 password is: -19 (Minus nineteen) or -19

Note: The dash (minus sign) is crucial. Input using the arrow keys.

Finding Specific Information

For specific details about the Eliwell SMP 5500, including exclusive passwords, consider the following steps:

  1. Consult the User Manual: The user manual or technical documentation provided with the device or available on the manufacturer's website is a good starting point.

  2. Contact Manufacturer Support: Eliwell's customer support or technical service can provide guidance on accessing the device and any specific requirements for configuration or maintenance.

  3. Authorized Distributors or Technicians: If you're working with a system that includes the Eliwell SMP 5500, consulting with authorized distributors or technicians can also yield the necessary information and support.

Security Considerations

  • Password Management: It's crucial to follow best practices in password management. This includes changing default passwords, ensuring passwords are complex and not easily guessable, and storing them securely.

  • Access Control: Limiting access to authorized personnel helps protect against accidental or malicious changes to the system's settings.

  • Documentation: Keeping documentation up to date, including password records (in a secure manner), is essential for ongoing management and troubleshooting.
