Pro Grow Dragon Series Smart Fan Controller

Automatic speed control for Pro Grow Dragon Series EC duct fans, Standard and Silenced, 150 to 300 mm. The controller reads temperature and humidity in the canopy and adjusts fan speed to suit, so your room stays on target without constant adjusting.

It runs two fans out of the box. The two synced PWM outputs send the same signal, so both fans move together. Choose Manual, Auto or Timer mode, and set high and low temperature and humidity alarms that ramp the fans to full speed when they're crossed. There's no power cord, because the fan powers the controller through its RJ12 cable.
