Selection of Dimensions The selection of the dimensions takes place according to the flow rate range specified by the consultant. Minimum total pressure differentials and flow rate tolerance The accurate adjustment of the flow rate setpoints is carried out using a flow rate scale, which is attached on each controller. For the acoustic characteristics in tables on page 8, duct air velocity is needed. This can be determined from the following table. 1) Additional factor to be taken into account Flow rate ranges . Vmin unit2) Dimensions H = 600, 800 and 1000 only available as TVJ-/TVJD-Easy!...

Acoustic Quick Selection 1) 4 dB/octave ceiling reduction and 5 dB/octave room attenuation have been allowed for in the calculation of case-radiated noise. Acoustic data for differential pressure up to 1000 Pa, see on-line design programme "Air terminal units". Please refer to leaflet no. 5/4/EN/.. for acoustic performance data and selection example.

Flow Rate Adjustment On each 7VJ-/TVT-Easy, a flow rate scale is available in order to determine the settings on site (see example size 500 x 200). Variable flow rate control The required flow rates must be adjusted by the customer. If \/min is set higher than \/max, then \/min is provided as a constant flow rate, even if a control signal is transmitted. If \/min is set on 0 %, then control is between shut-off and \/max. If the control signal falls below 0.1 VDC, the control damper closes. Constant flow rate control The constant flow rate can be set with the Vmin-potentiometer. The setting...
