Overview

Halton Workplace WRA is a controller especially designed for controlling the automation system of office spaces and meeting rooms. It is used for controlling the ventilation airflow, room temperature, and indoor air quality.

The Halton Workplace WRA room automation package consists of a controller unit and optional components depending on customer needs: a wall panel and sensors for temperature, CO2, occupancy, pressure, and condensation.

There are options available for the controller unit and wall panel, depending on the number of controls and sensors required. The Halton Workplace WRA room automation controller is always combined with other Halton products for adaptable and high-level indoor climate.

Application area

  • Controlling the ventilation airflow, room temperature, and indoor air quality in office spaces and meeting rooms
  • The Halton Workplace WRA room automation controller is an important part of the Halton Workplace system, controlling room units and airflow control dampers

Key features

  • Factory-tested controller and wiring, easy to install
  • Pre-installed project-specific parameters, quick to commission
  • Several operating modes based on occupancy, thermal comfort, and indoor air quality
  • Enables fully flexible layout solutions for changing needs in office environments
  • Highly energy-efficient and reliable system operation

Operating principle

The Halton Workplace WRA room automation controller operates with Variable Air Volume (VAV) dampers and active chilled beams of the Halton Workplace system. These are used for adjusting the ventilation airflow, room temperature, and indoor air quality in office spaces.

Each room unit in an office space can have its own dedicated Halton Workplace WRA room automation controller, or a single controller can control multiple room units. The Halton Workplace WRA room automation controller can automatically adjust the system according to the indoor environment level preferred by users. Each room unit having its own dedicated controller brings maximum flexibility.

Operating modes

The Halton Workplace WRA room automation controller has four operating modes for controlling the ventilation airflow in a room or area:

  • Unoccupied (minimum) for outside office hours
  • Standby (medium) during office hours when no occupancy is detected in the room or area
  • Occupied (normal) during office hours when occupancy is detected
  • Boost (maximum) for situations where the CO2 level rises above the desired level or more cooling is needed

Note: The corresponding terms used in the controller unit are Economy, Pre-comfort, Comfort, and Comfort max.

You can define the temperature setpoints for each operating mode separately.

1 Based on occupancy (unoccupied, standby, and occupied)
2 Based on indoor conditions (boost)

Airflow control

The supply and exhaust ventilation airflow control is based on occupancy detection as well as temperature and CO2 levels.

The Halton Workplace WRA room automation controller manages the room’s supply airflow rate by controlling the following:

  • Active chilled beams where the supply airflow rate is adjusted with the Operation Mode Damper (OMD) control. Products: Halton Rex Integrated VAV (R6O) and Halton Rex Exposed VAV (REO) chilled beams.
  • Active chilled beams where the supply airflow rate is adjusted with the Halton Air Quality (HAQ) control which can be accompanied with an on-off or position control damper (Halton PTS) for controlling the minimum airflow rate in the standby and unoccupied operating modes. Products: Halton Rex 600 (RE6), Halton Rex Exposed (REE), and Halton Rex Expander (RXP) chilled beams.

Both room and central zone exhausts are possible. In the case of room exhaust, the Halton Workplace WRA room automation 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 central zone exhaust is managed by a zone VAV control damper (Halton Max MDC).

Temperature control

The room temperature sensor can be integrated into a room unit (for example, a chilled beam) or the wall panel (optional).

In air-water systems, temperature is controlled by using water valves for controlling the water flow rate. If more cooling capacity is needed, the ventilation airflow rate can be increased.

Different operating modes have different temperature setpoints. Users can select the desired temperature level from the wall panel (optional).

Condensation sensor

A condensation sensor is used to prevent condensation in chilled beams. It can be specified when selecting Halton Workplace WRA room automation for chilled beams. If the sensor detects condensation, the Halton Workplace WRA room automation controller closes the cooling valves.

If there is no condensation sensor in a chilled beam, the condensation control must be done on the Building Management System (BMS) level.

Occupancy sensor

An occupancy sensor detects motion in a room or space and is used to control the ventilation airflow in the space based on occupancy. It can also be used for measuring brightness in the space. The occupancy sensor can be integrated into a room unit or it can be installed as a separate sensor.

If occupancy is detected in the space, the Halton Workplace WRA room automation controller increases the supply airflow rate. When occupancy is not detected, the airflow rate is decreased typically based on building material emissions.

CO2 sensor

A carbon dioxide (CO2) sensor is used to control the ventilation airflow rate based on the CO2 level of the indoor air. The CO2 sensor can be integrated into a room unit or it can be installed as a separate sensor. The Halton Workplace WRA room automation controller manages the ventilation airflow rate based on the CO2 level setpoint. If the CO2 levels in a space increase above the setpoint levels, the supply airflow rate is increased. The CO2 level is typically used as an indoor air quality indicator.

Window switch

The window switch is a magnetic switch that is installed to a window and connected to the Halton Workplace WRA room automation controller with a cable. It detects whether a window is open or closed. If the window is open, the Halton Workplace WRA room automation controller closes the cooling valves to prevent condensation.

Pressure sensor

A pressure sensor is used for the pressure measurement of supply air room units which is then used for calculating the supply ventilation airflow rate in the Halton Workplace WRA room automation controller. Controller type DXR2.E12P-102A has an integrated pressure sensor. With controller type DXR2.E18-102A, a separate pressure sensor is needed.

System settings

The parameters are pre-set at the factory and customer-specific settings are possible.

The system setpoints and functions are controlled using the Building Management System (BMS) via BACnet/IP or with a web browser. Users can adjust the room temperature from the wall panel (optional). After office hours, the temperature setpoint is reset to the default.

Design information

When designing an office space or meeting room, consider the following:

Should individual room units in a room have their own dedicated Halton Workplace WRA room automation controllers or should the whole room be controlled as one area?

    • If every terminal unit has its own dedicated controller, it allows for a more adaptable solution, enabling room layout changes and better individual control of the indoor environment.
    • One controller can control up to four terminal units (one primary + three secondaries)

Should the measurement sensors be integrated into a wall panel or should separate sensors be used?

    • If there is nowhere to install a wall panel (due to glass walls, for example), sensors can be integrated into room units or separate sensors can be used.
    • All sensors cannot be integrated into all room units. In this case, sensors can be integrated into the wall panel or separate sensors can be used.

Is the exhaust airflow damper controlled by the Halton Workplace WRA room automation controller or some other system?

    • If room-specific exhaust with a VAV damper is used, the room exhaust airflow is controlled by the Halton Workplace WRA room automation controller.
    • If zone exhaust is used, the exhaust airflow is controlled by a zone VAV control damper (Halton Max MDC).

Installation information

For the active chilled beams of the Halton Workplace system, the Halton Workplace WRA room automation controller unit is installed to the main product at the factory. It is also possible to remove the Halton Workplace WRA room automation controller unit from the main product and install it separately.

If there is nowhere to install a wall panel (due to glass walls, for example), sensors can be integrated into room units or separate sensors can be used.
