SMS Twin Fan Speed Controller
The 4.5A SMS Twin Speed Fan Controller is software controlled with motion flow technology unlike other controller that are mechanical. It reacts completely differently to normal controllers. SMS fan controllers scan your grow room to make a decision on a gradual increase or reduction of the speed of your fan. The SMS fan controller will then automatically find the appropriate constant level of the fans to maintain temperature.
The SMSCOM Fan controller is fantastic for taking the hard work and effort out of constantly having to change your fan speed manually. This twin 4.5A model by SMSCOM can handle both and inlet and extraction fan. It will automatically working out the required fan speed for you and balance both of the fans accordingly. You can use the fan controller as a single speed controller by simply leaving the inlet socket empty.
- Handles up to 2 fans totaling 4.5A (inlet and extraction).
- Automatically increases or decreases fan speed.

How to use:
To set up the SMS fan controller firstly connect your AC extraction fan into the right hand socket and your inlet into the left hand socket. If you don’t have an inlet fan, no need to worry, simply leave the socket empty. Set the left hand “minimum fan speed” knob to your desired lowest fan speed, the middle dial to the temperature and finally the right hand knob to the maximum allowed fan speed.
