General information

Application

All-in-one control engineering devices for VAV terminal units
Dynamic differential pressure transducer, electronic controller, and actuator are fitted together in one casing
Suitable for different control tasks depending on the specification of the setpoint value
The room temperature controller, central BMS, air quality controller or similar units control the variable volume flow control by specifying the setpoint values via a communication interface.
Suitable for room control X-AIRCONTROL zone module Modbus
Simple connection for supply voltage and communication with common RJ12 connection socket
Override controls for activating q_vmin, q_vmax, shut-off, OPEN position via Modbus register, BACnet objects or X-AIRCONTROL possible
Volume flow rate actual value is available as a network data point
Damper blade position is available as a network data point
Standard filtration in comfort air conditioning systems allows for use of the controller in the supply air without additional dust protection

With heavy dust levels in the room

Install appropriate exhaust air filters upstream, as a partial volume flow is routed through the transducer for volume flow rate measurement

If the air is contaminated with dust, fluff or sticky components

Use an attachment assembly with static differential pressure transducer

Control strategy

The volume flow controller works independently 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 parameterised in the controller at the factory (q_vmin: minimum volume flow rate, q_vmax: maximum volume flow rate)
Operating parameters are specified via the order code and parameterised in the factory

Operating modes

Modbus RTU: Setpoint value setting via X-AIRCONTROL or external software
BACnet MS/TP: Setpoint value setting via external software

Principle of operation

① Effective pressure transducer

② Actuator

③ Volume flow controller

④ Setpoint value signal

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 by measuring a 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 hence available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal volume flow rate (q_vnom).
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 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 volume flow rate setpoint value to the actual value and controls the integral actuator accordingly.
