The Twin Controller Pro is an automatic temperature controller. Unlike other controllers that shunt the fans from idle to full speed after the temperature is exceeded, the Twin Controller automatically calculates the exact operating speed for your fans to maintain the set temperature.

With the additional program added to the software you can remove excess humidity from the grow room during the lights off cycle. When the lights are turned off the Twin Controller PRO will automatically switch to the off mode. The Twin Controller PRO will automatically switch to another program, which every hour, gently increases the fan speed for long enough to remove excess humidity from the room, and when the lights come back on the Twin Controller PRO will return to its main program.

The secondary program can be activated at any time so the grower can choose to use this feature at any stage of the growing cycle.
