  • Volume flow rate control range: approx. 15 – 100 % of the nominal volume flow rate

  • Differential pressure range: 5 – 1000 Pa


Control component (attachments)

Electronic controller for the demand-based supply air or extract air flow control. Factory mounted to a VAV terminal unit, wired, tested and set to customer-specific parameters (immediately ready for use once installed). Control electronics using a microprocessor, with firmware and configuration settings stored in EEPROM memory and hence safe in case of a power failure. Choice of three actuator variants to ideally meet project-specific requirements.

Basic functions

  • RS: Supply air control

  • RE: Extract air control


It should be possible to configure and save up to 3 flow rate setpoint values; it should also be possible to close and open the damper blade by an external signal (override function). The controller should have a 0(2) – 10 V input for a flow rate setpoint value from an external source and be able to process this signal. It should be possible to implement the functions mentioned above with an optional expansion module for LonWorks, Modbus or BACnet. The controller monitors and controls the flow rate setpoint values and issues an alarm if there is a deviation. It should be possible to set alarm thresholds (parameters) as deviations (higher/lower) from the setpoint value. It should be possible to use the software to easily change control parameters so that they meet system or room requirements. Connections for all important communication and peripheral devices are located on the outside of the casing and are hence easily accessible. Indicator lights for alarms (on both sides), controller function (heartbeat) and communication should also be placed on the outside of the casing.

Conventional interfaces should be provided to connect the controller to higher-level systems:

  • 4 analogue inputs for the setpoint and for additional actual flow rate values

  • 3 analogue outputs for signalling the actual volume flow rate and the damper blade position as well as the volume flow rate setpoint to the slave controller

  • 5 digital inputs for volt-free contacts, selection of operating modes only with master (RMF) (min, max, closed, open, modulating)

  • 6 digital outputs (relays) for alarms, signalling of the operating mode; lighting and shading only with master (RMF)


2 control panels can be connected to the controller for the output of visual and acoustic alarms in case of volume flow rate deviations. Display of flow rate actual and setpoint values; also for room users to enter and set values. The controller should be designed for integration with a control system and hence allow for the connection of up to 24 TROX UNIVERSAL controllers to a communication cable; no addressing should be required (plug and play). It is possible to combine different equipment functions (volume flow rate, room pressure, duct pressure) within a system. It should be possible to expand the range of functions with expansion modules for different project requirements.

Equipment function

  • PRS: Room pressure control, supply air

  • PRE: Room pressure control, extract air
  • PDS: Duct pressure control, supply air
  • PDE: Duct pressure control, extract air


Maintenance of the required differential pressure through a permanent setpoint/actual value comparison in a closed loop. The pressure setpoint is either a parameter (constant pressure) or a controlled variable (variable pressure) that is received via an analogue input or a communication module (expansion). Room pressure control requires that positive pressure, negative pressure and 0 Pa differential pressure can be achieved. The controller should allow for override control to fully open or close the damper blade. An external differential pressure transducer measures the room or duct pressure; the measured value is then transmitted to the controller by means of a 0 – 10 or a 2 – 10 V DC voltage signal. This allows for some flexibility with regard to the differential pressure transducer for a project. An optional expansion module for volume flow rate measurement should allow for measuring the volume flow rate by means of the pressure controller. The controller monitors the required differential pressure and emits an alarm in case of deviations. Alarm thresholds (parameters) can be individually set and changed as deviations from the setpoint value. With a volt-free door contact on a digital input it should be possible to suppress alarms (for a certain period of time) and to freeze the damper blade in its current position. The controller should allow for override control to fully open or close the damper blade (digital inputs or communication modules). Connections for all important communication and peripheral devices are located on the outside of the casing and hence easily accessible. Indicator lights for alarms (on both sides), controller function (heartbeat), and communication are also on the outside of the casing. Conventional interfaces should be provided to connect the controller to higher-level systems: 4 analogue inputs for actual pressure and setpoint pressure, room volume flow rate, connection of external volume flow rates; 3 analogue outputs for actual pressure, damper blade position, actual volume flow rate (only with option V); 6 digital inputs (for volt-free contacts) and 6 digital outputs (relays) for alarms and control panels. 2 control panels can be connected to the controller for the emission of visual and acoustic alarms and for the display of room actual and setpoint pressure values, lighting, shading and operating modes; they also allow for control by users. The controller is designed for integration with a control system; up to 24 TROX UNIVERSAL controllers can be connected to a communication cable (plug and play, no addressing required). It is possible to combine different equipment functions (volume flow rate, room pressure, duct pressure) within a system. It should be possible to expand the range of functions with expansion modules for different project requirements. A transformer module allows for the connection of 230 V AC in case no 24 V AC/DC supply voltage can be provided. A transformer module with UPS function should be provided. It should be possible to expand optional volume flow rate measurement with a function for automatic zero point correction. It should be possible to connect the controller with communication modules to open bus systems (LonWorks, BACnet MS/TP, Modbus RTU, BACnet/IP and Modbus/IP). This will allow for the reading and writing of defined data points and parameters. This includes: differential pressure actual and setpoint values, damper blade position, override functions and alarms.

The system

Application

The TROX UNIVERSAL controller meets diverse, project-specific control requirements and can be used as a single controller or as part of a control system. The controller is typically attached to a VAV terminal unit, both in supply air and extract air systems, and controls volume flow rate, room pressure and duct pressure, either as a single device or in a system with other controllers. The desired range of functions depends on how you configure equipment function, control parameters and monitoring parameters. You can also use expansion modules to add more functions. Optional control panels allow you to be notified of alarms, see control status values, and change or influence operating modes.

TROX UNIVERSAL controller

VAV terminal units with a TROX UNIVERSAL controller are typically installed in ventilation and air conditioning systems, at points where an airflow has to be changed in some way. You can use the controller as a single component for the control of a variable or constant supply air flow, for example, or to maintain a constant pressure in a duct. The controller does, however, not only fulfil its control function, but also alarm and monitoring functions. An actuator moves the damper blade of the VAV terminal unit. Various suitable actuators are available: actuators with normal and short running times (150 s and 3 s) as well as spring return actuators with normal running time (150 s) for safety-related applications. Voltage signals and/or switch contacts as well as (optional) communication modules are used to send default setting values and status values to the controller or receive them from the controller. The TROX plug and play communication system allows you to combine up to 24 controllers into one functional unit, e.g. for the master-slave control of supply air or extract air.

Communication system

Combining several TROX UNIVERSAL controllers to a system offers the highest potential. You can connect up to 24 TROX UNIVERSAL controllers in a room to one communication cable, even if they are used for different equipment functions (volume flow rate control, room pressure control, duct pressure control); they will then be automatically recognised and integrated, i.e. by plug and play. The communication cable may be up to 300 m long.

You can define one controller in such a system as the master controller by activating the room management function (RMF) on that controller and by setting on this controller all of the parameters that are relevant to the volume flow control of the room. You can also use this master controller to have inputs or outputs for analogue signals and for flow rate setpoint values (out), actual values (in), alarms (out) and operating modes (in/out). If the master controller includes a communication module, the values mentioned and other information are made available to higher level systems.

Control panel

The control panel (optional) allows you to access the system and display relevant information. Using it is simple. Function buttons for enabled functions are shown and easy to use. An integral service socket provides service staff with direct access to the controller for configuration and diagnosis.

Room management function

Application

  • The room management function is a software option that provides functions for the entire room

  • Within a system of up to 24 TROX UNIVERSAL controllers you can activate the room management function on one controller (supply air, extract air, room pressure or duct pressure controller)

  • Factory set parameters for the room management function (if ordered as a master)

  • On-site activation using the EasyConnect configuration software or TROX app EasyCon

Central interface point for room functions

  • Room operating mode default setting for all controllers in the room; priority can be selected

  • Room operating mode default setting using switch contacts, LonWorks, BACnet, Modbus, or room control panel

  • Volume flow rate setpoint for the room

  • Extract air led system: Based on extract air flow rate setpoint value for the room; extract air controller with room management function as master, supply air controller as slave

  • Supply air led system: Based on supply air flow rate setpoint value for the room; supply air controller with room management function as master, extract air controller as slave

Use the controller with the RMF to set the room parameters. The master controller sends the volume flow rate actual value (and other values) via the communication cable to the slave controller. The slave controller uses this value to determine the flow rate setpoint value. In case of air transfer a constant supply air to extract air difference will be maintained.

Room management function

  • Setpoint volume flow rate default setting for a room

  • Centralised operating mode default setting for all controllers in a room (standard mode, reduced operation, increased operation, shut- off, OPEN position)

  • Connection of BE-LCD control panel, optional

  • Consolidated alarms for a room


Connection to higher-level systems
The controller can be connected to higher level systems with expansion modules for open bus systems (LonWorks, Modbus, BACnet). The function varies according to the controller equipment function.

  • Master controller (RMF): Central interface point for room data

  • Slave controller: Local data interface for this controller

Application

  • Kitchens with special requirements, isolation wards, clean rooms, operating theatres

  • For demanding requirements on volume flow control and pressure control

  • Data communication with higher level systems


System setup
The system consists of a VAV terminal unit with a TROX UNIVERSAL controller for supply air, a VAV terminal unit with a TROX UNIVERSAL controller for extract air, and a room pressure controller. A plug-in communication cable connects the controllers. The system can be expanded: Up to 24 TROX UNIVERSAL controllers can be connected to a communication cable. Only one room pressure controller can be used per room. Whether room pressure control is based on supply air or on extract air depends on the project. Use the room pressure controller to activate the room management function. The controller with the RMF then acts as the master controller for the room.

  • Extract air led system: Room pressure controller with room management function in the extract air flow; the extract air controller controls the volume flow rate for the room based on demand; the supply air controller follows the extract air controller; the room pressure controller ensures that the setpoint pressure is maintained

  • Supply air led system: Room pressure controller with room management function in the supply air flow; the supply air controller controls the volume flow rate for the room based on demand; the extract air controller follows the supply air controller; the room pressure controller ensures that the setpoint pressure is maintained 

The master controller sends the volume flow rate actual value (and other values) via the communication cable to the slave controller. The slave controller uses this value to determine the flow rate setpoint value. The room pressure controller maintains the variable or constant setpoint pressure by opening the control damper blade to a greater or lesser degree. Use the controller with the RMF to set the room parameters.

Supply air control, extract air control and room pressure control with a master-slave setup, combined with duct pressure control

Application

  • Clean rooms, ICUs, operating theatres

  • For demanding requirements on volume flow control and pressure control

  • Data communication with higher level systems


System setup

The system consists of a VAV terminal unit with a TROX UNIVERSAL controller for supply air, a VAV terminal unit with a TROX UNIVERSAL controller for extract air, and a room pressure controller. In the room there is also an enclosure that is to be provided with supply air. A VAV terminal unit maintains a constant duct pressure in the supply air duct. A plug-in communication cable connects the controllers. The system can be expanded: Up to 24 TROX UNIVERSAL controllers can be connected to a communication cable. Whether room pressure control is based on supply air or on extract air depends on the project. Use the room pressure controller to activate the room management function. The controller with the RMF then acts as the master controller for the room.

  • Extract air led system: Room pressure controller with room management function in the extract air flow; the extract air controller controls the volume flow rate for the room based on demand; the supply air controller follows the extract air controller; the room pressure controller ensures that the setpoint pressure is maintained

  • Supply air led system: Room pressure controller with room management function in the supply air flow; the supply air controller controls the volume flow rate for the room based on demand; the extract air controller follows the supply air controller; the room pressure controller ensures that the setpoint pressure is maintained 

Use the controller with the RMF to set the room parameters. Room pressure and duct pressure values can be configured with the respective pressure controller and are output on that same controller. The room pressure controller is used to maintain the variable or constant setpoint pressure by opening the control damper blade to a greater or lesser degree. The master controller sends the volume flow rate actual value via the communication cable to the slave controller. The slave controller uses this value to determine the flow rate setpoint value. In case of air transfer a constant supply air to extract air difference will be maintained. The duct pressure controller maintains the constant or variable setpoint pressure; the duct pressure controller can also be fitted with an optional volume flow rate measuring point. The controller then transmits the volume flow rate actual value to the system such that it can be used for room balancing. Control of the damper blade of VAV terminal units with a a pressure controller is a closed loop.

Room management function

  • Connection and use of BE-LCD control panel

  • Centralised operating mode default setting for all controllers in a room (standard mode, reduced operation, increased operation, shut- off, OPEN position)

  • Setpoint volume flow rate default setting for a room

  • Consolidated alarms for a room, including pressure alarm


Connection to higher-level systems

Expansion modules for open bus systems (LonWorks, Modbus, BACnet) can be used to connect the controller to higher-level systems; these modules can be used as follows:

  • on the controller with the RMF: central interface point for room data

  • on the slave controller: local data interface for this controller
