General information

Application

All-in-one control devices for VAV terminal units Types TVE and TVE-Q
Static differential pressure transducer, controller electronics and actuator combined in one casing
For clean and contaminated air in ventilation and air conditioning systems:

E.g. in the extract air area with dust, fluff, sticky or moist components
Application examples: extract air from changing rooms and shower areas, hospital bed rooms, production facilities, corridor areas such as in schools and hospitals

Various control options based on corresponding setpoint specification
Room temperature controller, management and control equipment (MCE), air quality controller and others control the variable volume flow regulation by specifying setpoint values via communication interface
Override control for activating qvmin, qvmax, shut-off or open position via Modbus register or switch or relay possible (depending on interface configuration)
The actual volume flow rate value is available as a network data point
The damper blade position is available as a network data point

Control strategy

The volume flow controller works independently of the duct pressure
Differential pressure fluctuations do not result in permanent volume flow rate changes
To prevent the control from becoming unstable, a dead band is allowed within which the damper blade does not move
Flow rate range is set in the controller at the factory (qvmin: minimum volume flow rate, qvmax: maximum volume flow rate)
Operating parameters are specified via the order code and set in the factory

Operating modes

Modbus (M): setpoint value default via X-AIRCONTROL

Communication interface

Modbus RTU, RS485
Data point list see Modbus register list

Service interface

Construction

TR0VM-024T-10I-DS10-MB with RJ12 connection socket

Commissioning

As the volume flow rates are factory-set, the terminal units have to be installed at the specified locations only
Network integration requires commissioning steps
Operating parameters can be customised by the client (via display, adjustment device, PC software or via Modbus register)

Useful additions

Adjustment device Type GUIV3-M (order code AT-VAV-G3)
Room control X-AIRCONTROL with zone module Modbus type X-AIR-ZMO-MOD

Volume flow controllers are characterised by a closed control loop for controlling the volume flow, i.e. measuring - comparing - adjusting. The volume flow rate is obtained by measuring a differential pressure. This is done via a differential pressure sensor. The integrated differential pressure transducer converts the differential pressure into a voltage signal. The actual volume flow value is available as a data point. Due to the factory-set values, 100% always equals the nominal volume flow rate (qvnom). The volume flow setpoint is specified by a higher-level controller (e.g. room temperature controller, air quality controller, MCE). The controller compares the volume flow setpoint with the current actual value and adjusts the internal actuator, according to the control deviation. Variable volume flow control can be set between qvmin and qvmax. It is possible to override the room temperature control by override control, e.g. via a shut-off.

This specification text describes the general properties of the product.

Category

Compact controller for volume flow rate

Application

Control of a constant or variable volume flow rate setpoint. Electronic controller for connecting a reference value and tapping an actual value for integration into a Modbus-based MCE. The actual value relates to the nominal volume flow rate so that commissioning and subsequent adjustment are simplified

Area of application

Static transducer for polluted air in ventilation and air conditioning systems

Actuator

Integral; slow-running (running time 100 s for 90°)

Installation orientation

Not critical

Connection

RJ12 connection socket with rubber cap cover, suitable for TROX X-AIRCONTROL zone module X-AIR-ZMO-MOD
connection terminals are optional

Supply voltage

24 V AC/DC

Interface/signalling

Modbus RTU (RS485) factory-activated

Interface information

Modbus: volume flow rate setpoint and actual value signal, damper blade position, forced control, i.a.

System connections

Modbus connection for optional expansions, e.g. TROX X-AIRCONTROL zone module Modbus

Special functions

Clearly visible external indicator light for signalling the functions: regulated, not regulated, and power failure
Display for actual values, parameterisation and for test functions
Activation of qvmin, qvmax, Closed, Open via:

Modbus commands (Modbus operating type)

Parameter setting

Specific parameters for VAV terminal unit are factory-set
Operating values: qvmin, qvmax Interface type: Modbus factoryset

Subsequent customisation via display and control element directly on the device or with optional tools:

Adjustment device, PC software (cable connection in each case)
in Modbus mode also via Modbus register access

Factory condition

Functional test under air using reference measurement on a regularly validated test rig in accordance with DIN EN ISO 9001 to check the function and control accuracy of the complete volume flow controller
Adjustment of the device-specific parameters under air by reference measurement on a regularly validated test rig if in accordance with DIN EN ISO 9001
The test report of the factory parameterisation, functional test and adjustment must be made available after delivery of the volume flow controller

Equivalence criteria

The test report of the factory parameterisation, functional test and adjustment under air by reference measurement on a regularly validated test rig in accordance with DIN EN ISO 9001 is provided
