Description

One Controller for Your Intake and Extraction Fans

The SMS Hybrid Controller Pro 4A runs your intake and extraction fans from one unit rated to 4 amps (900W), setting fan speed from a temperature probe through a heavy-duty 5-step transformer. Its light sensor adds a night-time humidity routine, running the fans one step faster for 7 minutes each hour in the dark, so swings are caught and corrected before they hit growth.

Struggling to keep temperature and humidity stable across separate devices?

Adjusting intake and extraction fans by hand always lags behind what plants need, letting temperature and humidity drift. The Hybrid Controller Pro sets both fans from the room temperature so the environment stays consistent automatically.

Key Benefits

  • 4A rated output for confident control of connected equipment
  • Hybrid automation: temperature-led fan speed plus a night-time humidity routine
  • Three dials for minimum speed, temperature and maximum speed
  • Stable conditions from coordinated intake and extraction
  • Fewer boxes on the wall - one controller for both fans

How to Use

  • Plug your intake fan into FAN AIR IN and your extraction fan into FAN AIR OUT
  • Keep total combined load within the 4A rating
  • Set the minimum speed, temperature and maximum speed dials and let it manage both fans automatically
  • Review readings periodically and adjust setpoints as plants move between growth stages
