What is the SMS Hybrid Controller 4 Amp Mk2 used for?

These units control grow room fans in order to remove excess humidity during the lights off cycle. When the lights in a grow room switch off, this controller automatically switches to another program. This allows it to gently increase fan speeds for long enough to remove excess humidity from the room. Then, when the lights come back on this controller will switch back to its main program. Likewise, this system is also completely silent in operation, there will be no buzzing or humming from your fans with this!

Furthermore, this controller also features a 5m NTC temperature probe, allowing the unit to be position in absolutely any location in your grow room. Similarly, it’s onboard temperature control software helps to provide faster reaction times, lower idling speeds and incredible accuracy.

Where can you use the SMS Hybrid Controller 4 Amp Mk2?

This system is for use within a professional indoor grow room set up, featuring two fans, up to a maximum combined output of 4 amps. It will maintain your grow room’s temperature by automatically adjusting the fans speed between the controllers maximum and minimum settings.

How to use the SMS Hybrid Controller 4 Amp Mk2                              

Start by connecting both of your fans to the unit and position the probe inside your grow room. Next, set the lowest speed for both of your fans and the required temperature for the grow room. After this, your controller should now maintain the temperature by automatically adjusting the fans.
