Got an EC Fan? Get temperature control on a budget with a G.A.S EC1 Thermostatic Speed Controller!

Fan speed up or slow down according to your grow room temperature.

No power supply is needed - your controller's powered by the connected EC fan via an active cable (included).

Simply connect your controller & place your temperature probe. Then set your temperature, minimum speed & maximum speed. Your controller does the rest!

• Connects to EC Rev Vector, Silenced EC Rev Vector (with white active cable)
• No power supply needed (powered by the connected fan!)
• Plug & Play (active cable included)
• Maximum fan speed (to reduce noise)
• Minimum fan speed (for odour, CO₂ & humidity control)
• LED alert (when maximum temperature has been surpassed)

Connect your controller to your fan via the active cable supplied.

Place your temperature sensor in the middle of your room.

Your controller's plug & play! Everything's controlled with just 3 dials.

This is the maximum temperature you want your room to be.

Your bandwidth is always 2^oC - your controller will ramp up your fan speeds 2^oC before your maximum temperature is reached.

This is the minimum speed fan need to run at for CO₂, odour & humidity control. This'll probably be 20% - 30% for most people, but may be even more, depending on how much air you draw in.

This is the maximum fan speed - this is mostly there to keep fans running quieter.

This lights up when your actual grow room temperature is higher than your temperature setting. 

Manage both intake and extraction fans
