TrolMaster - EC Fan Controller (EFC-1)

Variable-speed EC fan control for the Tent-X system

The TrolMaster EFC-1 EC Fan Controller gives the Tent-X Control System precise variable-speed control over compatible EC intake and exhaust fans, using either PWM or 0-10V output. Poor airflow is one of the most common causes of trouble indoors: humidity builds, temperatures climb and plants end up weak or with poor bud development. The EFC-1 lets Tent-X automatically hold correct negative pressure and steady airflow, keeping fresh, CO2-rich air moving through the canopy for stronger veg and better bloom.

Key Benefits

• Variable-speed EC fan control driven directly by the Tent-X control system
• Dual signal compatibility with both PWM and 0-10V EC fans
• Precise intake and exhaust management to maintain correct grow-tent pressure
• Better airflow control for healthier, more stable indoor conditions
• Plug-and-play RJ12 installation for a quick, simple connection
• Purpose-built for Tent-X grow room control systems

How to Use

1. Connect the EFC-1 module to the Tent-X controller using the RJ12 connection.
2. Select the correct output mode for your EC fan type (PWM or 0-10V).
3. Plug the EC fan control cable into the EFC-1 RJ12 port.
4. Assign the fan position in Tent-X: F1 for exhaust, F2 for intake.
5. Configure the fan settings in the controller so airflow adjusts to environmental conditions.
6. To run both intake and exhaust, connect a second EFC-1 via a Y-splitter or SPH-1 splitter to the DEVICE port, with the appropriate fan on each adaptor.
