General information

Application

All-in-one control engineering device for VAV terminal units
Dynamic differential pressure transducer, electronic controller and actuator are fitted together in one casing
For clean air in ventilation and air conditioning systems

The standard filtration enables use in the supply air without additional dust protection measures
Application examples: Offices and classrooms

In the event of a strong occurrence of dust, install appropriate extract air filters upstream, as a partial volume flow is routed through the transducer for volume flow rate measurement.
If the air is heavily contaminated with dust, fluff, sticky, moist components, an attachment with a static differential pressure transducer must be used, e.g. XD0 or XS0.

Application examples: Extract air from changing rooms and shower areas, hospital bedrooms
XS0 (for types TVE and TVE-Q)
XD0 (for TVR, TVJ, TVT, TZ-Silenzio, TA-Silenzio, TVZ, TVA, TVRK)

Various control options based on setpoint value default setting
Room temperature controllers, building automation, air quality controllers and others control the variable volume flow control by specifying setpoint values via an analogue signal
Override controls for the activation of qvmin, qvmax, shutoff and open position possible via switch contacts or relay
The actual volume flow rate value is available as a linear voltage signal

Control strategy

The volume flow controller works independent 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 (hysteresis) is maintained which is not moved by the damper blade
The flow rate range for the controller is set at the factory

qvmin: minimum volume flow rate
qvmax: maximum volume flow rate

Operating parameters are set at the factory according to the order code

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 signal for volume flow rate setpoint value
Analogue signal for volume flow rate actual value

Technical information

Principle of operation for type TR0V-024T-05I-DD15 (type TVE)

① Effective pressure transducer

② Actuator

③ Volume flow controller

④ Setpoint value via analogue signal

⑤ Shaft with effective pressure channel

Air terminal units control the volume flow in a closed loop, which means: measurement – comparison – adjustment. The volume flow rate is obtained by measuring a differential pressure. This is done with a differential pressure sensor. An integrated differential pressure transducer converts differential pressure into a voltage signal. The actual volume flow rate is available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal flow rate (qvnom). The volume flow setpoint value is specified by a higher-level controller (e.g. room temperature controller, air quality controller, central BMS). Variable volume flow control can be set between qvmin and qvmax. It is possible to override the room temperature control by forced switching, e.g. for a shut-off The controller compares the volume flow setpoint with the current actual value and adjusts the internal actuator according to the control deviation.
