Product details
This is the control circuit board for Tacony-built central vacuum power units in the BF4, BF6 and CI4 series, ordered as part TC-PC46BF.
This board sits between every wall inlet and the drive motor, deciding when the motor should turn on. Each inlet valve carries a low-voltage sensing loop, and inserting a hose closes that loop, telling the board to energize the motor; pulling the hose back out opens the loop again and should cut power. Once that sensing path fails, two symptoms are typical: nothing responds no matter which inlet you plug into, or the motor comes on but keeps running after the hose is disconnected.
- Part number: TC-PC46BF
- Fits: BF4, BF6 and CI4 central vacuum power units

Central vacuum boards are matched to a specific unit series and are not interchangeable across the wider product line, so confirm the model printed on your power unit against this listing, or compare it with your existing board, before ordering. Ships to you in 2-5 business days.
