Modbus RTU zone module

Functional description

Zone modules are electronic control components for single room control. They control temperature, air quality and humidity, based on demand and based on occupancy.

A zone module controls the air terminal units for supply air and extract air, and a heating valve and a cooling valve.

A control panel is used to operate a zone module.

A single room control system can be expanded by centralised functions if a zone master is used. One zone master module and up to 25 zone modules form a segment. Up to five cascading master modules form a section with up to 125 zone modules.

There are two ways to configure and operate the system:

  • Using the zone master module
  • Using the X-AIR-CP-2T control panel with touch screen

Volume flow control

The X-AIR-ZMO-MOD zone module activates up to 3 electronic air terminal units (2 for supply air, 1 for extract air) and provides the volume flow rate setpoint value. The actual volume flow control is handled by a volume flow controller.

The volume flow rate setpoint value depends on the operating mode, the no. of air terminal units and the respective nominal volume flow rates. Parameters that are stored in the volume flow controller, e.g. Vmin and Vmax, are automatically read and evaluated by a zone module.

The operating mode default can be set either on the zone master module (i.e. centrally) or on the room control panel.

Operating modes

  • Automatic mode
  • Increased operation (Vmax)
  • Reduced operation (Vmin)
  • Shut-off

Operating modes set on the X-AIR-CP-2T control panel apply only for a defined period of time. After this period has elapsed, the zone returns to Automatic mode. Shut-off remains active until a user changes the operating mode again.

Damper blade positions and volume flow rate actual values of the air terminal units are signalled to the zone module and then forwarded to higher-level systems; the purpose is energy-efficient fan control.

Temperature control

A sensor measures the room temperature or extract air temperature, which is constantly compared to the setpoint value. In case of any deviation, the system controls airflows and/or water flows in such a way that the required room temperature is achieved (again). Variants:

  • All-air system: Cooling is achieved by increasing the volume flow rate
  • All-water system: Heating valve and cooling valve are actuated
  • Air-water system: Variable volume flow, followed by valve control if necessary
  • Air-water system: Valve control followed by variable volume flow control if necessary

It is also possible to combine room temperature control and supply air temperature control (cascade). With this type of control the deviation from the room temperature is used to determine the supply air temperature setpoint. In addition, the supply air temperature is limited by a minimum value and a maximum value (can be configured).

Larger zones can be equipped with another two temperature sensors. The target value will then be the average value.

Air quality control

The air quality is measured with an air quality sensor (VOC or CO2) placed in the room or in the extract air. If the measured contaminant content exceeds a certain value, the system keeps increasing the supply and extract air flows until the air quality improves. If a zone is fitted with heating or cooling valves, the system activates these valves in order to control the room temperature.

Humidity control

A sensor measures the relative humidity of the extract air; the value is then compared to a threshold value. If the relative humidity exceeds the threshold value, the system keeps increasing the supply and extract air flows in order to decrease the humidity in the room.

If a zone is fitted with heating or cooling valves, the system activates these valves in order to control the room temperature.

Window contact and frost protection

The zone module has a volt-free digital input for the connection of a window contact or a frost protection sensor. It is possible to connect a dew point sensor instead of a window contact. Users can choose how to use the digital input:

  • Window contact The damper blades of the air terminal units, the heating valve and the cooling valve close.
  • Dew point monitor The cooling valve closes such that condensation is prevented. Volume flow control remains unaffected.
  • Frost protection sensor The heating valve opens fully to protect the heat exchanger. Volume flow control remains unaffected.

Motion detector

Another volt-free digital input is available for the connection of a motion detector (X-SENS-PIR-SM, X-SENS-PIR-FM). The volume flow rate is controlled as long as a room is occupied. If the room becomes unoccupied, volume flow control ends after a set delay, which can be configured.

Heating or cooling request

Two digital outputs on the zone module can signal a heating or cooling request and activate a heating or cooling system.

Increasing requirements on the energy efficiency of ventilation and air conditioning systems as well as EU regulations can be fulfilled with intelligent control engineering solutions.

X-AIRCONTROL is a control system that uses information from sensors and actuating elements to optimise ventilation and air conditioning systems. It calculates what all is required to achieve a comfortable room climate, and controls fans, pumps and valves accordingly.

X-AIRCONTROL is a modular system that can be used to optimise individual functions or a whole range of functions for a project.

  • Evaluate the damper blade positions of all air terminal units
  • Optimise fan control (optimiser function)
  • Evaluate the heating and cooling required for a zone
  • Calculate the supply air temperature setpoint value for the air handling unit
  • Configure the system, display the system configuration and manage alarms – all this from a central point

X-AIRCONTROL zone

An X-AIRCONTROL zone is an area where air conditioning parameters such as temperature and humidity are controlled based on demand and based on the occupancy. These are usually single rooms, but it is possible to create individual zones also in larger areas, e.g. in open plan offices.

  • Each zone is controlled by a zone module
  • Sensors detect various air conditioning parameters as well as occupancy
  • Actuators control these conditions
  • Room occupants can use control panels to adapt the system to their individual comfort requirements
  • A zone module can be used either as a stand-alone unit or as part of a larger system

X-AIRCONTROL segment

A segment is a group of up to 25 zone modules; the entire segment is controlled as a unit, i.e. the same conditions apply to the entire segment. Grouping zones into segments is necessary when these zones are to be controlled centrally and when data from these zones are to be evaluated. A segment may be a floor in a building, the wing of a building or simply areas that are used differently from adjacent areas.

  • A segment is controlled by a zone master module.
  • Sensors detect various air conditioning parameters that are relevant to the segment, e.g. the outdoor air temperature
  • Digital inputs and outputs are used to activate functions for a segment, e.g. to activate a fire alarm
  • A webserver (integral part of the zone master module) is used to configure the entire segment, to display the segment configuration, to monitor all segment functions and to manage alarms
  • Modbus TCP and BACnet IP interfaces allow for the integration with higher-level systems
  • A segment can be treated as an individual unit (stand alone) or it can be combined with other segments to form a section

X-AIRCONTROL section

A section is a group of up to 5 segments. A section may consist of up to 5 zone master modules and 125 zone modules.

  • A section is controlled by the first zone master module
  • If the first zone master module is connected to the control system of an air handling unit, the system can be operated most efficiently
  • It is possible to have several, independent sections and hence create larger structures; there are virtually no limits to the size of the overall system

Stand-alone solution for a zone

A single zone module and a room control panel can be used to control a single room.

  • Integrate air terminal units (up to 2 for supply air and 1 for extract air)
  • Activate valves for cooling and heating
  • Measure the temperature and configure the zone with the X-AIR-CP-2T control panel (required)
  • Define schedules independent of the central BMS
  • Simple wiring
  • Connect components using plug and play

Use additional sensors (optional) to include other parameters.

  • Occupancy
  • Air quality
  • Humidity

Interconnecting zones for multi zone operation

Up to 25 zone modules and another 4 zone master modules can be connected to a zone master module such that a system of up to 125 zones is achieved. Different zone modules (Modbus, MP bus or Analogue) can be combined and connected with plug and play.

  • Up to 25 zone modules per zone master module (segment)
  • Up to 5 zone master modules (section)
  • Up to 125 zone modules in a section

Each zone module controls and maintains individually the required conditions for the particular zone (single room) for which it is used. The zone modules are connected in series; 100 m cables (module to module) allow for linking even large areas or different buildings. Each zone master module and each zone module is automatically assigned a unique address (plug and play), which simplifies commissioning.


Advantages of a zone master module

  • Central access for displaying and setting individual zone parameters using the integral webserver
  • Ethernet connection allows for easy integration with higher-level systems and for remote maintenance via the internet
  • Option to connect a WiFi router (WLAN)

System solution with X-CUBE compact

If a project is to include X-CUBE compact air handling units, zone control with X-AIRCONTROL is the ideal system solution. With such a solution the air handling unit's X-CUBE Control system not only activates fans, dampers and other components of the air handling unit, it also acts as the zone master.

The X-CUBE compact air handling unit can serve up to four zones. If up to four zone modules are connected to the X-CUBE compact, no additional zone master module is required.

X-CUBE Control includes an Ethernet interface and a webserver for the configuration of the air handling unit, yet it can also be used to configure the connected zone modules.

  • The zone master function is included in X-CUBE Control
  • Up to four zone modules per X-CUBE compact unit, including different variants (Modbus, MP bus or Analogue)
  • Integral webserver for configuring the air handling unit and the zone modules
  • Remote maintenance is possible
  • Expansion option: Up to 25 zone modules per air handling unit if an additional zone master module is used

System solution with X-CUBE

X-CUBE air handling units with X-CUBE Control offer zone master functions; no additional units or devices are necessary.

  • Control of the air handling unit
  • Zone master function for up to 125 zone modules

If X-CUBE Control is to be used for the zone master function, all entries, both for the X-CUBE and for the zone modules, have to be made on the X-CUBE Control touch screen. This includes configuration, display of the system configuration, monitoring, and alarm management.

Since X-CUBE Control includes an integral webserver, the system can be accessed from anywhere with the correct password.

  • Remote access via webserver
  • Display of actual operating values
  • Adjustment of parameters
  • Maintenance management
  • Alarm alert by e-mail or SMS

Design information

  • Design and select sensors depending on the required zone functions
  • Ensure that the zone module variants (Modbus, MP bus, Analogue) and actuators (volume flow controllers and valve actuators) you select are compatible
  • For optimum energy efficiency select zone modules with bus compatible actuators (Modbus, MP bus) as only these will signal information on valve and damper positions
  • If you use an X-CUBE air handling unit with integral X-CUBE Control system, you may connect up to 125 zone modules without the need for an additional zone master module
  • If you use an X-CUBE compact air handling unit, you may connect up to 4 zone modules without the need for an additional zone master module
