Description
Simple stepless control for EC fans with an RJ45 connection
The GrowControl Fanspeed EC RJ45 lets you adjust the output of a compatible EC fan without requiring a complex climate controller. Designed for EC fans with an RJ45 control connection, this compact manual controller provides stepless adjustment from 0–100%. It is particularly useful when you want straightforward control over the extraction rate in your grow tent or indoor growing space.
Manual adjustment from 0–100%
Fan output is set directly using the rotary control. This allows you to reduce airflow when less extraction is required or increase the fan output when ventilation demand rises. There are no programmes or climate parameters to configure, making the controller a straightforward option for manual ventilation management. Other control solutions can be found in the fan speed controller range.
Designed for EC fans with an RJ45 control port
This version of the FanSpeed EC is intended specifically for EC fans equipped with a compatible RJ45 control connection. Check the control interface of your fan before connecting the controller, as EC fan connections can differ between models. Suitable options can be found in the range of EC duct fans. GrowControl also offers a separate FanSpeed EC version for fans using a 3.5 mm jack connection.
