Control components for VAV terminal unit with dynamic transducer

Compact device for use with VAV terminal units 

  • Controller, dynamic differential pressure transducer and actuator in one casing
  • Use in ventilation and air conditioning systems, only with clean air
  • Suitable for constant and variable volume flow rates
  • Activation of override controls via external switch contacts
  • Volume flow rates qvmin and qvmax are set in the factory and saved in the controller
  • Change of operating parameters using adjustment devices
  • Service access for manual adjustment devices and PC configuration software
  • Simple terminal connection without the use of additional junction boxes (for types TVE and TVE-Q)

 

General information

Application

  • All-in-one control devices for VAV terminal units

  • Dynamic effective pressure transducer, electronic controller and actuator are fitted together in one casing
  • Dynamic differential pressure transducer for clean air in ventilation and air-conditioning systems
  • Various control options based on setpoint value default setting
  • Volume flow rate control is based on setpoint values received from room temperature controller, central BMS, air quality controller or other devices as an analogue signal.
  • Override controls for activating qvmin, qvmax, shut-off or OPEN position can be set with a switch or relay
  • The actual volume flow rate value is available as a linear voltage signal


If air is contaminated with dust, lint, sticky, moist or slightly aggressive particles:
  • Use Compact controller XS0 or XD0 with static effective pressure transducer instead of the Compact controller XB0 described here
  • XS0 (for TVE and TVE-Q series)
  • XD0 (for TVR, TVJ, TVT, TZ-Silenzio, TA-Silenzio, TVZ, TVA, TVRK)

Control strategy

  • The volume flow controller works dependently 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 in the controller set in 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

  • Variable or constant value

Variable operation (V)

  • Setpoint value default setting via analogue interface
  • Signal voltage range corresponds to qvmin to qvmax


Constant value mode (F)

  • A setpoint signal is not required, setpoint value corresponds to qvmin


Interface

Analogue interface with adjustable signal voltage range

  • Analogue signal for volume flow rate setpoint value
  • Analogue signal for volume flow rate actual value (factory setting), alternatively: analogue signal for damper blade position (adjustment by others required)


Signal voltage ranges

  • 0 – 10 V DC
  • 2 – 10 V DC


Parts and characteristics

  • Transducer based on dynamic measuring principle. It can 

    only be used with clean air, as a partial volume flow is passed through the transducer
  • Actuators with overload protection
  • Release button to allow for manual operation (only 227V-024-10-DD3)
  • Connecting cable with 4 wires, approx. 0.9 m, halogen-free (only 227V-024-10-DD3)
  • Terminals with cover (only TR0V-024T-05I-DD15)
  • Service interface

 Construction

  • Type 227V-024-10-DD3 for TVR
  • Type 227V-024-10-DD3 for TVJ
  • Type 227V-024-10-DD3 for TVT up to 1000x300 or 800x400
  • Type 227V-024-10-DD3 for TZ-Silenzio, TA-Silenzio
  • Type 227V-024-10-DD3 for TVZ, TVA
  • Type 227V-024-10-DD3 for TVM
  • Type TR0V-024T-05I-DD15 for TVE

Commissioning

  • Due to the volume flow rates set at the factory, always ensure that the terminal units are only installed at the specified locations
  • After successful installation and wiring, the controller is ready for use
  • Operating parameters can be adjusted by the customer (via the adjustment device)


Useful additions

  • Adjustment device GUIV-A (order code AT-VAV-G) for 227V-024-10-DD3
  • Adjustment device GUIV3-M (order code AT-VAV-G3) for TR0V-024T-05I-DD15

Easy_gc_09ai.png

A closed control circuit for regulation of the volume flow rate, i.e. measuring - comparing - adjusting, is characteristic of air terminal units.
The volume flow rate is measured via the differential pressure (effective pressure). This is done via a differential pressure sensor. An integrated differential pressure transducer converts the effective pressure into a voltage signal. The volume flow rate actual value is available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal volume flow rate (qvNom).
The volume flow rate setpoint value is specified by a higher-level controller (e.g. room temperature controller, air quality controller, central BMS). Variable volume flow control results in a value between qvmin and qvmax. It is possible to override the room temperature control, e.g. by a complete shut-off of the duct.
The controller compares the volume flow rate setpoint value to the actual value and controls the integral actuator according to the system deviation.


Category
