Raumtemperatur -Regler . . . If Vmin is set higher than Vmax, then Vmin min is provided as a constant volume flow. . If Vmin is set on 0 %, then control is between shut-off and Vmax. If the control signal falls below 0.1 VDC, the control damper closes (leakage flow only). . Product presentation Trox TVR-Easy Connection examples Variable volume flow control Room temperature controller If the control signal falls below 0.1 VDC, the control damper closes (leakage flow only).
The constant volume flow can be set with the Vmin potentiometer. The position of the Vmax-potentiometer is unimportant. . . Product presentation Trox TVR-Easy Connection examples Constant volume flow control
