7.4.2Parameter menu (P2)

Parameters are the way of conveying the commands of the user to the frequency converter. The parameter values can be edited by entering the Parameter Menu from the Main Menu when the location indication P2 is visible on the display. The value editing procedure is presented in Figure 7- 6.

Push the Menu button right once to move into the Parameter Group Menu (G#). Locate the parameter group desired by using the Browser buttons and push the Menu button right again to enter the group and its parameters. Use again the Browser buttons to find the parameter (P#) you want to edit. Pushing the Menu button right takes you to the edit mode. As a sign of this, the parameter value starts to blink. You can now change the value in two different manners:

1Just set the new desired value with the Browser buttons and confirm the change with the Enter button. Consequently, the blinking stops and the new value is visible in the value field.

2Push the Menu button right once again. Now you will be able to edit the value digit by digit. This editing manner may come in handy, when a relatively greater or smaller value than that on the display is desired. Confirm the change with the Enter button.

The value will not change unless the Enter button is pushed. Pressing the Menu button left

takes you back to the previous menu.

Several parameters are locked, i.e. not editable, when the drive is in RUN status. The frequency converter must be stopped in order to edit these parameters.

The parameters values can also be locked using the function in menu S6 (see Chapter 7.4.7.2).

You can return to the Main menu anytime by pressing the Menu button left for 1—2 seconds.

The basic parameters are listed in Chapter 8.3. You will find the complete parameter lists and descriptions in the HVAC and Multi-Control Application manuals.

Once in the last parameter of a parameter group, you can move directly to the first parameter of that group by pushing the Browser button up.

NXL specifications

Honeywell NXL is an advanced building management system designed to optimize the efficiency of HVAC, lighting, and security systems within commercial buildings. It incorporates cutting-edge technologies to enhance operational performance, improve energy savings, and provide a comfortable environment for occupants.

One of the standout features of Honeywell NXL is its integration capabilities. The system allows seamless connections between various subsystems, facilitating a unified approach to building management. This interoperability means that data from different systems can be aggregated, analyzed, and applied to enhance overall building performance.

The Honeywell NXL employs a user-friendly interface that empowers facility managers to easily navigate through critical information. The intuitive dashboard offers real-time analytics and visualizations, providing insights into energy consumption, system performance, and occupant comfort. Users can quickly identify inefficiencies and make informed decisions to improve operational effectiveness.

In terms of technologies, Honeywell NXL utilizes IoT connectivity, which enables devices and systems within the building to communicate with one another. This connectivity allows for remote monitoring and control, which is essential for effective facility management. By leveraging IoT technology, facility managers can receive alerts, conduct diagnostics, and perform maintenance proactively, reducing equipment downtime and avoiding costly repairs.

Another significant characteristic of the Honeywell NXL is its robust data analysis capabilities. The system collects vast amounts of data from sensors and connected devices, which is then processed to identify patterns and trends. This analytical approach not only aids in energy management but also enhances occupant comfort by adjusting parameters in real-time based on occupancy and environmental conditions.

Energy management is a critical issue for modern buildings, and Honeywell NXL addresses this with advanced optimization strategies. The system can implement demand response capabilities, adjusting energy usage based on peak periods or grid demands, ultimately saving costs and reducing environmental impact.

Moreover, Honeywell NXL places a strong emphasis on security features. Its design includes integrated surveillance and access control systems, ensuring the safety of occupants while facilitating efficient access management.

In summary, Honeywell NXL is a comprehensive building management solution that combines user-friendly design, IoT connectivity, advanced data analytics, energy optimization, and enhanced security features. Its ability to integrate various building systems makes it an essential tool for contemporary facility management, promoting efficiency and sustainability in building operations.
