Novar Executive Controller Replacement

Novar Executive Controller Replacement

Lowering costs is a challenge every facilities manager faces and, at present, it’s a particularly pressing one. In broad terms, meeting the challenge successfully means maximizing asset usage and improving operational efficiency. The latter is particularly important because simply upgrading or replacing assets to get better results isn’t always a practical approach. Sometimes, it makes far more sense to make sure the assets you already have are primed to operate more efficiently. That’s possible if you can achieve greater control of their performance.  However, as we’ll see below, it isn’t always straightforward to do. So, let’s look at what steps we can take.

The unitary controller issue

The key step we’ll discuss in this blog relates to unitary controllers for both HVAC and lighting. To understand why we need to know what these are and what role they play so let’s start with some definitions. What, exactly, are these?

Unitary controllers are a technology that sits within the domain of building automation. Their use leads to improved overall performance of HVAC and lighting systems, mainly by making them more energy efficient. These unitary controllers report to an executive controller which acts as the lead automation device for the building.  Both unitary and executive controllers can be sourced from different manufacturers.

Controller technology is fast developing, and this has created something of a problem because the latest, improved functionality is desirable. In many cases, a new executive controller can provide a bevy of new features and functionality.  Facilities managers thus want the freedom to choose their executive controllers without being locked-in to their legacy products which may well no longer be meeting their evolving requirements.

Presently, many managers are reported to be dissatisfied with the performance of their existing executive controllers, but they feel constrained because swapping them out in what amounts to a vendor lock-in situation isn’t easy.

Among available executive controller options, the NexRev Freedom solution allows for flexibility with an open platform design.  NexRev also continues to develop new features and functionality within their Freedom solution.

Why it matters

The Novar replacement issue is important because facilities will - over time - have invested significant sums in the hardware infrastructure which exists downstream of their Novar executive controllers. This means that they can’t cost-effectively solve the problem by simply ripping and replacing their executive controllers if the result is that various downstream devices are impacted and need to be replaced too. What can they do?

At NexRev, we’ve developed an answer: the N-Net Driver that allows NexRev Freedom to integrate directly to Novar unitary controllers. This driver allows the end user to upgrade their executive controller to a NexRev Freedom solution, without requiring replacement of downstream Novar legacy hardware and thus allowing the user to end its Novar relationship. As a result, our N-Net driver dramatically reduces the cost of achieving increased efficiency and improved performance by delivering the benefit of a new system without the expense of one.

To summarize the benefits in simple terms, installing the driver:

  • Ends the Novar lock-in
  • Allow reuse of existing unitary hardware
  • Swaps out the Novar executive controller with the NexRev panel
  • Provides access to IoT enabled EMS
  • Supports AI based insights and recommendations
  • Enables access to robust analytics and reporting
  • Improves customer service
  • Improved user experience that helps drive innovation

Furthermore, moving to the NexRev panel via the N-Net driver also gives facilities managers access to NexRev Enterprise, a powerful cloud-based EMS / BMS for managing multi-site operations.

Improve operational performance and maximize returns

The bottom line here is simple. Facilities managers today require a general, integrated control platform to optimize the performance of their HVAC and to better control costs.

Many times, such a platform will need to accommodate existing Novar system functionality easily and cost-effectively. NexRev’s N-Net Driver has been built to enable the desired outcome to be achieved. In so doing, it allows existing Novar investments to continue to be leveraged while the user simultaneously severs ties with Novar itself.
