Service tools:
VAV terminal units control the volume flow in a closed loop, i.e. measurement – comparison – correction. The volume flow rate is measured via the effective pressure. This is done via an effective pressure sensor. An integrated differential pressure transducer converts the effective pressure into a voltage signal. The volume flow rate actual value is available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal flow rate (qvNom). 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 qvmin and qmax. 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.

Analogue interface 0 – 10 V DC or 2 – 10 V DC
The analogue interface can be set for signal voltage range 0 – 10 V DC or 2 – 10 V DC using the service tools. The assignment of the setpoint value or actual value of the volume flow rate to the voltage signal is shown in the characteristic line displays.
Setpoint value default setting
Variable operation:
Constant value mode:
Actual value as feedback for monitoring or tracking control
Override control
For special operating situations, the volume flow controller can be put in a special operating mode (override control). The following modes are possible: control qvmin, control qvmax, damper blade in the OPEN position, damper blade CLOSED. Override control can be activated by:
Override control CLOSED via control signal on control signal Y
The override control CLOSE can also be activated by observing certain conditions with the command signal. The following table summarises the boundary conditions.
Signal voltage range | 0 – 10 V DC | 2 – 10 V DC | 2 – 10 V DC | 2 – 10 V DC | |
---|---|---|---|---|---|

Shut-off voltage (PC-Tool) | Not possible | Not applicable | 0.1 V 2 | 0.5 V 2 | |
Damper closes when Y is reached | Y < 0.45 V DC | Not possible | Y < 2.36 V DC | Y < 0.1 V DC | Y < 0.5 V DC |
Control is activated when Y is reached | Y > 0.55 V DC (*1) | Y > 0 V DC | Y > 2.44 V DC | Y > 0.1 – 2 V DC: qvmin Y > 2 – 10 V DC: qvmin – qvmax | Y > 0.5 – 2 V DC: qvmin Y > 2 – 10 V DC: qvmin – qvmax |
Notes:
1 Activation of control operation with 0 –10 V and qvmin set to = 0:
The applicable volume flow rate range depends on the basic unit (TVJ/TVT: 20 – 100% of qvnom; all other basic units: 10 – 100 % of qvnom). This means that setpoint defaults can be achieved only from 2 V DC (with TVJ/TVT) or 1 V DC (with other basic units).
2 Shut-off voltage 0.1 V DC or 0.5 V DC:
If there is a possibility or risk that the 0.1 V setpoint may not be undershot on a system (DDC output or long cable length), the shut-off voltage can be changed to 0.5 V with PC-Tool. This is only possible with signal voltage range 2 – 10 V DC.
Note on mode setting 0.1 V DC or 0.5 V DC
If there is a possibility or risk that the 0.1 V setpoint may not be undershot on a system (DDC output or long cable length), the shut-off voltage can be changed to 0.5 V with PC-Tool. This is only possible with signal voltage range 2 – 10 V DC.
Digital communication interface MP bus
General information
MP bus is not an open system, but manufacturer-dependent bus system for which Belimo and its partner companies provide components and software. Examples include the TROX XAIR-ZMO-MP zone module and software for the X-AIRCONTROL room control system, also the UK24xxx Belimo gateways and the fan optimiser.
MP bus allows you to have setpoint defaults and override controls preset and to read out damper positions and volume flow rates. As for the network, any topology can be used: star, ring, line, tree and hybrid topologies.
Neither special cables nor terminal resistors are required for the wiring, but the cable lengths are limited and depend on:
Example: MP bus with 5 LMV-D3-MP compact controllers on 24 V AC supply. Total power rating: 5 × 4 VA = 20 VA.
For more information on MP buses see the Belimo documentation at https://www.belimo.com.
VAV compact controller with MP bus
Control component BC0 is fitted with an MP bus communication interface and can be interconnected with up to 8 TROX/Belimo MP devices (damper actuators, valve actuators, VAV controllers) on a Belimo MP bus. The controller on the MP bus receives its control signal from the higher-level central BMS so that the volume flow rate setpoint can be achieved.
MP bus mode starts automatically as soon as the control component is assigned an MP address with a service tool. A standard Compact controller with an MP address becomes a bus-compatible system controller with a wide range of additional benefits.
MP bus requires that the U connection is used. The U connection can then no longer be used for analogue actual value feedback.
