Halton Vita VRA is a controller especially designed for controlling the automation system of a hospital patient room. It is used for controlling the ventilation airflow, room temperature, and lighting in the room.
The Halton Vita VRA controller consists of a controller unit and a user panel. The Halton Vita VRA controller is always combined with other Halton products for the desired operation.
The Halton Vita VRA controller controls Variable Air Volume (VAV) dampers, Halton Vita Patient Rex (VPR) chilled beams, and Halton Vita Patient Ava (VPA) radiant panels that are used for adjusting the ventilation airflow, room temperature, and lighting in a hospital patient room.
Fig.2. Overview of the Halton Vita VRA controller
The layout of a hospital patient room can vary in configuration from a one-bed room to a room with several beds. For example, each VPR chilled beam or VPA radiant panel can have its own dedicated Halton Vita VRA controller, or a single controller can be shared by the entire patient room. The controller set-up can be changed afterwards if needed.
The Halton Vita VRA controller has three operating modes for controlling the ventilation airflow in the room:
Users can select the desired operating mode from the Halton Vita VRA user panel.
The Halton Vita VRA controller manages the room’s supply ventilation airflow rate as follows:
The Halton Vita VRA controller manages the room’s exhaust ventilation airflow rate by controlling a VAV damper, such as Halton Max Ultra Circular (MUC) or Halton Max One Circular (MOC).
The room temperature sensor is located in the Halton Vita VRA user panel. The temperature is controlled using water valves for controlling the water flow rate. Cooling capacity can be enhanced by increasing the ventilation airflow.
Users can select the desired temperature level from the user panel.
The Halton Vita VRA controller uses Digital Addressable Lighting Interface (DALI) for controlling the lighting, that is, switching the lights on or off or dimming the lights.
An extra light button (accessory available separately) can be installed near a patient bed, for example. The light button is connected to the controller unit with a cable.
A condensation sensor is used to prevent condensation in chilled beams. It can be specified when selecting chilled beams. If the sensor detects condensation, the Halton Vita VRA controller closes the cooling valves.
The window switch (accessory available separately) is a magnetic switch that is installed to the window and connected to the Halton Vita VRA controller unit with a cable. It detects whether the window is open or closed. If the window is open, the controller closes the cooling valves to prevent condensation.
The system setpoints and functions are controlled using either the Halton Vita VRA user panel or the Building Management System (BMS) via BACnet/IP or Modbus TCP/IP. Both control routes (user panel or BMS) are synchronised.
The Halton Vita VRA controller has three user levels for adjusting settings on the its user panel:
As a basic user, you can adjust some basic settings, such as the operating mode, room temperature, or lighting. No login is required.
As a commissioning user, you can access settings that are configured in the commissioning phase.
As a service user, you can access the following:

A factory-tested and assembled room automation system. Includes control, measuring, and adjustment components.
When designing a patient room, consider the following:
The Halton Halton Vita VRA controller unit is usually installed to the main product (Halton Vita Patient Rex (VPR) chilled beam or Halton VPA radiant panel) at the factory. It is possible to remove the controller unit from the main product and install it separately, for example, in cases where all service should take place outside the room.
The Halton Vita VRA user panel must be installed in a place that is easily reachable, for example, next to a door.
Space requirements
The Halton Vita VRA controller unit is usually installed to the main product. Enough space must be reserved around the controller unit for service. If there is a solid ceiling, there must be a service hatch close to the controller unit.
The wiring must only be carried out by qualified personnel following the local regulations.
For more information on wiring, see the project-specific wiring diagrams. In addition, you can find some example wiring diagrams in Technical reference data and a general system wiring diagram on the inside of the cover of the Halton Vita VRA controller unit.

The Halton Vita VRA controller unit is installed to the main product (Halton Vita Patient Rex chilled beam or Halton Vita Patient Ava radiant panel) at the factory and configured. External wiring needs to be checked before the system start-up.
The controller addressing is pre-set at the factory. If addressing needs to be changed later, it can be done using a computer via a USB cable. All system parameters can be modified using the Halton Vita VRA user panel or using the BMS via the communication bus.
