Variable Temperature Control (VTC-1D)

One of our most popular variable speed fan controls

The Variable Temperature Control (VTC-1D) automatically controls the temperature in a room by adjusting the speed of variable speed fans.

When the temperature is at the temperature set point, the VTC-1D operates the fans at the idle speed setting. When the temperature exceeds the set point, the VTC-1D increases the speed. When the temperature drops below the set point, the VTC-1D shuts off the fans (in shut-off mode) or operates the fans at idle speed (idle mode).

The VTC-1D is ideal for poultry, livestock, greenhouse, or light-industrial buildings.
