SMS Twin Controller PRO 7A

The Twin Controller PRO works in exactly the same way as the original Twin Controller but has an additional programme added to its software to remove excess humidity from the growroom during the lights off cycle.
When the lights in the growroom switch off, the Twin Controller PRO will automatically switch to another programme that every hour, gently increases the fans speed for just long enough to remove excess humidity from the room. When the lights come back on, the Twin Controller PRO switches back to its main programme.
The secondary programme can be activated at anytime so the grower can chose to use this function at any stage of the growing cycle. When not activated the controller acts in exactly the same way as the original Twin Controller both day and night.
