Mission Control TwinFan Controller

One Controller Running Both Your Intake and Extraction Fans Automatically

The Mission Control TwinFan Controller is an intelligent temperature controller that manages both an intake and an extraction fan from a single unit, adjusting fan speeds together to hold your grow room at a steady temperature instead of leaving you to ride two fans by hand. By continuously monitoring temperature and balancing air pressure, it improves plant health, nutrient uptake and crop performance across veg and flower. It suits grow tents and grow rooms where getting fresh air in and stale air out in balance makes a real difference.

Key Benefits

• Controls two AC fans (intake and extraction) from one controller
• Maintains balanced negative pressure to manage odour and clear stale air
• Night-Pulse mode keeps gentle airflow moving during lights-off to control humidity without overcooling
• Adjustable minimum and maximum fan speeds plus Xtra Fan-Speed fine-tuning
• Smooth speed control for quieter running than on/off switching
• Three power ratings (4.5A, 7A, 14A) to match different ventilation systems

Tired of Chasing Temperature and Humidity Swings by Hand?

Adjusting two separate fans every time the temperature drifts is a losing game, and those gaps are exactly when humidity climbs and mould risk rises. The TwinFan Controller automatically balances intake and extraction to hold your target temperature while keeping room pressure under control, and Night-Pulse keeps a little air moving overnight so humidity doesn't creep up in the dark cycle.

How to Use

1. Mount the controller in a dry, accessible location.
2. Connect your intake and extraction fans to the designated outputs.
3. Position the temperature sensor at canopy height, away from direct airflow or grow lights.
4. Place the Night-Pulse sensor where it can detect your lighting cycle.
5. Set your target temperature plus minimum and maximum fan speeds.
6. Adjust Xtra Fan-Speed if needed to fine-tune airflow and negative pressure.
7. Let it regulate automatically, checking the sensors periodically for accuracy.
