SMS Twin Fan Speed Controller 4.5A

The SMS Twin Fan Speed Controller is a unique product that represents a real step forwards in automatic temperature control.

Unlike other controllers that simply shunt fans from idle to full speed after the temperature is exceeded, the SMS Twin Controller will automatically calculate the exact running speed for your fans and adjust them slowly to maintain the required temperature you have set. This new technology provides much more accuracy with your temperature control, limits fan noise and guarantees negative pressure inside the room.

This is a plug and play unit and requires no wiring, just simply plug in your fans and set the temperature you require and the SMS Twin Fan Speed Controller will take care of the rest.
