General information

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
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, or sticky and moist components, an attachment with a static differential pressure transducer must be used, e.g. XS0-J6
Application examples: Extract air from changing areas and showers, hospital bedrooms
Various control options based on setpoint value default setting
Suitable for X-AIRCONTROL room control, Modbus zone module
Control circuits for e.g. temperature, humidity, and air quality control the variable volume flow by specifying setpoint values via the communication interface
Simple connection for supply voltage and network with one shared RJ12 terminal socket
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
The damper blade position is available as a network data point

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 zone (hysteresis) is maintained, in which the damper blade is not moved
The flow rate range for the controller is set in the factory (qvmin: minimum volume flow rate, qvmax: maximum volume flow rate)
Operating parameters are defined by the order code and parameterised at the factory

Operating modes

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

Communication interface

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

Network integration requires commissioning steps
Operating parameters can be adjusted on site (using the display, an adjustment device, or the Modbus register)

3 Volume flow controller
4 Setpoint value via BACnet, 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.

XM0–J6	Setpoint value default setting via:	Actual values via:	corresponds to order key option	Menu configuration (Mode)
Analogue operation *	analogue 0 - 10 V	analogue 0 - 10 V	V or F	CA0
Analogue operation *	analogue 2 - 10 V	analogue 2 - 10 V	V or F	CA2
Modbus operation	Modbus register setpoint	Modbus register actual value or analogue 2 - 10 V	M	CB

* 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.
