A real step forwards in automatic temperature control. Unlike other controllers that simply shunt fans from idle to full speed after temperature is exceeded, the Twin Controller automatically calculates the exact running speed for your fans to maintain the temperature you set. This new method provides more accurate temperature control, limits fan noise and guarantees negative pressure inside the room. Simply plug in your fans, set the temperature and the Twin Controller will take care of the rest.

SMSCOM twin fan tech specs:

  • Accurate to +/- 1 degree
  • Supplied with a 5m probe
  • 5 year manufacturers warranty

  • How to use:

    Just plug in your fans and set the temperature dial to your desired temperature - Then sit back and the fans will monitor variables and adjust the fans as necessary.

    Make sure the combined amperage of the fans does not exceed the load rating.

    User can also set the maximum fan speed which will not be exceeded - you can prevent fans from ramping up too loud.

    The minimum fan speed is also user adjustable to maintain airflow.
