Nucleus is the state-of-the-art controller integrated with Etheos,
the newest platform developed by VDA for the hospitality market.

Hotels worldwide use guest room management systems (GRMS) to surprise and delight guests by controlling lighting, HVAC, drapery, and guest services through intuitive smart control panels.

One important device in a GRMS platform is not even used by the guest; it is the main in-room controller. On VDA-Telkonet’s new platform Etheos, this main controller is called Nucleus. Nucleus operates behind the scenes, in a discrete location out of the guest’s sight. It serves as the “brain” of the room. It is the main controller in each guest room through which all commands and data are funneled between the guest room and Etheos, VDA Telkonet’s GRMS platform.

VDA Telkonet has designed a Wi-Fi version of Nucleus. Using its Wi-Fi capabilities to connect to the hotel’s existing wireless network saves the cost of additional ethernet network devices. The Nucleus controller is also available as Nucleus Ethernet.

Designed to take hotel automation to the next level, Nucleus runs on powerful microprocessor architecture integrated with a flexible modular hardware configuration.

Nucleus integrates with the room’s smart devices. It is fully programmable, including I/O, scenarios, keypad features, and more. Nucleus can be expanded to control additional room fixtures, including the latest voice control solutions, dimmers, DALI lights, and more by communicating with an integration server. Through the integration server, VDA’s Nucleus easily integrates with other systems in the hotel, such as PMS, BMS, door locks and more.

With its powerful integrated processor, the flexible Nucleus controller can process large amounts of data which is forwarded to the Etheos platform.
The Nucleus controller easily integrates with most HVAC systems on the market. 

The Nucleus controller is equipped with four independent Modbus ports to manage up to 80 smart devices with no data latency. This increases the number of devices managed by a single unit, beneficial in large areas such as hotel suites and condo units. Nucleus is fully compatible with the entire catalog of VDA intelligent devices based on the Modbus protocol.

Nucleus takes advantage of relays that are appropriately sized for light control. This is an advantage because it avoids additional wiring costs deriving from bulky auxiliary power contacts. Additionally, this increases reliability and durability over time.

A built-in USB port is designed for easy programming and quick maintenance operations. It offers secure access to the controller’s “brain” to configure the device with the dedicated mobile app. Hotel maintenance workers can also use the mobile app to perform maintenance operations quickly, keeping guest room maintenance times to a minimum.

The cloud-based GRMS platform enables facility monitoring from anywhere, within or outside the hotel, using any device capable of launching an Internet browser.

Complex scenario algorithms can be configured, such as “Welcome” and “Guest Re-entry” based on occupancy, time of day, and other statuses.
Nucleus controller can be configured at any time: before the commissioning of the system; during the installation process, and by remotely profiling Nucleus using cloud-based programming tools.
Once programmed, even if the connection with the cloud is lost, it remains functional. All inputs and outputs are fully configurable from cloud-based tools which can be accessed with a browser from any personal computer or mobile device.
