Allgemeine Informationen

Application

All-in-one control devices for VAV terminal units types TVE and TVE-Q
Dynamic differential pressure transducer, electronic controller, and actuator are combined in one casing
Dynamic transducer for clean air in ventilation and air conditioning systems
Standard filtration in comfort air-conditioning systems allows the controller to be used in the supply air without additional dust protection measures
Various control options based on setpoint value default setting
Suitable for X-AIRCONTROL room control, Modbus zone module
By specifying setpoints via the communication interface, the control circuits for e.g. temperature, humidity, air quality control the variable air volume flow
Simple connection for supply voltage and network with one shared RJ12 connection socket
Override controls for activating q_vmin, q_vmax, shut-off, OPEN are possible using the Modbus register
The actual volume flow rate value is available as a network data point
The damper blade position is available as a network data point

If air is contaminated with dust, lint, sticky, moist or slightly aggressive particles:

Use the XS0-J6 control module (instead of the XM0-J6 compact controller described here)

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 is set 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 set in the factory

Operating modes

Modbus (M): setpoint value default via X-AIRCONTROL

Communication interface

Modbus RTU, RS 485
Data point list see Modbus register list

Parts and characteristics

Transducer based on dynamic measuring principle. It can only be used with clean air, as a partial volume flow is passed through the transducer
Overload proof actuator
RJ12 connection socket with cover
Display and control elements for easy menu navigation
Menu navigation allows for adjusting operating parameters and communication interface
Service interface

Construction

TR0VM-024T-05I-DD15-MB with RJ12 connection socket

Commissioning

As the volume flow rates are factory set, the terminal units have to be installed at the specified locations
Network integration requires commissioning steps
Operating parameters can be adjusted by others (using the display and control elements, 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

Function, Specification text, Order code

① Differential pressure transducer
② Actuator
③ Volume flow controller
④ Setpoint via Modbus or 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 effected 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. Du to the factory adjustment, 100% always equals the nominal volume flow rate (q_vNom).
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_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.

Interface configuration of the control component

The communication interface for the control component is pre-set to Modbus at the factory for use with the X-AIRCONTROL zone module. Only the Modbus address must be set by the customer, depending on the use in the supply air and extract air. For other applications, data transmission speed and format must be adapted on site according to the network environment.

Analogue operation *	analogue 2 - 10 V	analogue 2 - 10 V	V or F	CA2

* It is not possible to use the analogue interface in combination with the RJ12 connection socket provided with the XM0-J6 variant. Therefore, the configuration register 122 (interface mode) must not be changed on site. To use an analogue interface, type XM0 must be installed.
