General information

Application

All-in-one control device for VAV terminal units
Dynamic differential pressure transducer, control electronics and actuator combined in a single 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 depending on the terminal unit type, e.g. XD0 or XS0
Application examples: Extract air from changing rooms and shower areas, hospital bedrooms
Various control options based on setpoint value default setting
Room temperature controllers, building automation and control systems, air quality controllers and others control the
variable volume flow control by specifying setpoint values via an analogue signal
Override control for activating qvmin, qvmax, shut-off or OPEN position can be set with a switch or relay
The volume flow rate actual value is available as a linear voltage signal

If air is contaminated with dust, lint, sticky, moist or slightly aggressive particles: do not use an Easy controller

Construction

LMV-D3AL-F TR for LVC
TR0VE-024T-10I-DD15 for TVE, TVE-Q
LMV-D3A-F TR for TVR
LMV-D3A TR for TZ-Silenzio, TA-Silenzio, TVZ, TVA
327V-024T-15-004 for TVJ, TVT up to and including 1000 × 500
SMV-D3A TR for TVT from 1000 x 600

Parts and characteristics

Transducer based on dynamic measuring principle can only be used with clean air since a partial volume flow is passed through the transducer
Mechanical stops for limiting the damper blade positions (not for TVE and TVE-Q)
Actuators with overload protection
Transparent protective cap or terminal cover (depending on version)

Interface

Analogue signal 0 – 10 V DC

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 is allowed within which the damper blade does not move
Volume flow parameters can be easily changed by the customer

Operating modes

Operating mode variable volume flow rate, qvmin: minimum volume flow rate, qvmax: maximum volume flow rate
Operating mode Constant value, qvmin: Constant volume flow rate, qvmax: 100 %

Commissioning

Operating values q_vmin, q_vmaxto be set on site with potentiometer on the outside of the housing without additional adjustment tools

Principle of operation LVC, TVR, TZ-Silenzio, TA-Silenzio, TVZ, TVA, TVJ, TVT

1 Differential pressure transducer

2 Actuator

3 Volume flow controller

4 Setpoint value signal

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. The integrated differential pressure transducer converts the 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 (q_vNom).
The volume flow setpoint is specified by a higher-level controller (e.g. room temperature controller, air quality controller, building management system) or by switching contacts. Variable volume flow control can be set between_vmin and q_vmax. 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.
Volume flow parameter q_vmin and q_vmaxcan be set on potentiometers.

This specification text describes the general properties of the product.
