Trox LVC - Control Ranges of VAV Terminal Units; Volume Flow Rate Scale

6.1.1 Control ranges of VAV terminal units
Each V
AV terminal unit with Easy controller has a sticker with the volume flow rate scale. Note the individual volume
flow rate and control ranges of the respective combination of the VAV terminal unit and the control component.
The usable volume flow rate and control range is shown in the following table or on the scale sticker of the VAV
terminal units, Fig. 21 .

6.1.2 Volume flow rate scale
Fig. 21: Scale sticker example TVR/200/Easy
1 Minimal adjustable volume flow rate
2 Type of controller, here e.g. TVR
3 Nominal size
4 Arrow indicating the airflow direction
5 Maximum adjustable volume flow rate
6 Nominal volume flow rate in [m³/h], [l/s] and [cfm]
The scale sticker serves as an aid for setting the volume flow control range. The scale is individual for the combina-
tion of control unit, nominal size and mounted control component.
The grey shaded percentages (1 and 5) document the usable control range of the respective V
AV terminal unit type.
The right edge of the scale at 100% documents the respective nominal volume flow rate in [m³/h], [l/s] and [cfm].
The percentages thus represent the ratio of the respective volume flow rate to the nominal volume flow rate.
