General information

Application

All-in-one control device for VAV terminal units type 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 as well as hospital bedrooms, production facilities and corridor areas - e.g. in schools

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, OPEN position, possible via the Modbus register
The actual volume flow rate value is available as a network data point
Damper blade position, e.g. for fan optimisation, is available as a network data point

Control strategy

The volume flow controller works independently of duct pressure
Pressure fluctuations do not cause any permanent volume flow deviations
A dead zone (hysteresis), within which the damper blade is not moved, ensures stable regulation
The volume flow range for the controller is factory-set (qvmin: minimum volume flow, qvmax: maximumvolume flow)
Operating parameters are defined in the order code and factory-set

Operating modes

Modbus (M):

Setpoint specification via X-AIRCONTROL

Communication interface

Modbus RTU, RS485
Data points see Modbus register list

Construction

TR0VM-024T-10I-DS12-BN with RJ12 connection socket

Commissioning

As the volume flow rates are factory-set, the air terminal units must be installed only at the designated locations
Operating parameters can be adjusted by the client (using the display, an adjustment device, or the 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

Technical information

1 Differential pressure transducer
2 Actuator
3 Control component
4 Setpoint via Modbus
5 Shaft with effective pressure channel

Volume flow controllers are characterised by a closed control loop for controlling the volume flow, i.e. measuring - comparing - adjusting.
The volume flow 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).
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.
The controller compares the volume flow setpoint with the current actual value and adjusts the internal actuator, according to the control deviation.
