Variable volume flow control
If Vmin is set higher than Vmax, then Vmin min isprovided as a constant volume flow.
. . .
If Vmin is set on 0 %, then control is between shut-off andVmax. If the control signal falls below 0.1 VDC, the controldamper closes (leakage flow only).
..
If the control signal falls below 0.1 VDC, the controldamper closes (leakage flow only).
