General information

Application

All-in-one control device for VAV terminal units type TVE and TVE-Q
Dynamic effective pressure transducer, electronic controller and actuator are fitted together in one casing
For clean air in ventilation and air-conditioning systems; the standard filtering 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, use attachment group with static differential pressure transducer, e.g. XSMB0
Application examples: Extract air from changing rooms and shower areas, hospital bed rooms
Various control options based on setpoint value default setting
Volume flow rate control is based on setpoint values received from room temperature controller, MCE, air quality controller or other devices as an analogue signal or via communication interface
Override controls for activating q_vmin, q_vmax, shut-off, open position via Modbus/BACnet register or switch or relay possible
The actual volume flow rate is available as a network data point or as a linear voltage signal
Damper position, e.g. for fan optimisation, is available as a network data point

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 which is not moved by the damper blade
The flow rate range for the controller is set in the factory (q_vmin: minimum volume flow rate, q_vmax: maximum volume flow rate)
Operating parameters are set at the factory according to the order code

Operating modes

BACnet (B):

Setpoint value specification via BACnet objects

Analogue - variable operation (V):

The setpoint value is set via the analogue interface, the signal voltage range corresponds to q_vmin – q_vmax

Analogue - fixed value operation (F):

A setpoint signal is not required, setpoint value corresponds to q_vmin

Alternative adjusting possible on site:

Modbus: Setpoint specification via Modbus registers

Interface

Communication interfaces

BACnet MS/TP, RS485, data points see Tables BACnet PICS
Modbus RTU, RS485, see Modbus register list for data points

Analogue interface with adjustable signal voltage range

Analogue signal for volume flow setpoint
Analogue signal for actual volume flow rate (factory setting)
Alternatively: analogue signal for damper position (on-site conversion required)

Note:

Interface type according to order code detail
Operating mode parameterised at the factory, changeover possible on site

4 Setpoint value via BACnet, Modbus or analogue signal
5 Shaft with effective pressure channel

VAV terminal units control the volume flow in a closed loop, i.e. measurement – comparison – correction.
For volume flow rate measurement the effective pressure is measured first. This is done with a differential pressure sensor. The integral differential pressure transducer transforms the effective 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 rate setpoint value comes from a higher-level controller (e.g. room temperature controller, air quality controller, central BMS). Variable volume flow control results in a value between q_vmin and q_vmax. It is possible to override the room temperature control, e.g. by a complete shut-off of the duct.
The controller compares the differential pressure setpoint value to the actual value and controls the actuator accordingly if there is a difference.
