Release Date 11.07.2025

Changes

  • FB 'BELIMO_P_22RTX_1U00X_2_FULL'

    • Operating mode - parameter 'eEcoBoostOnOffIconMode' = BELIMO_P_22RTX_1U00X_2_ICON_MODE.PRESENCE_BUTTON: The parameter 'xVisuPresence' is now declared as input 'xVisuPresence'.

      • The two parameters mentioned above must not be changed while online. Reason: The FB 'HVAC.Button1' does not detect parameter changes during online operation

    • An updated application representation 'BELIMO_P_22RTX_1U00X_2_FULL_ANWENDUNG' has been added.

    • Adjustment of the documentation

New features

  • new FB 'BELIMO_P_22RTX_1U00X_2_FULL'. This FB allows the complete configuration (addresses 110..149) of all parameters in the 'Service' area. Use of the 'Belimo Assistant' app is therefore optional.
