The TrolMaster EFC-1 EC Fan Control Adapter provides variable-speed control of compatible electronically commutated fans using either PWM or 0-10V control signals, allowing ventilation to be integrated into compatible TrolMaster control systems.
Modern EC fans are designed to vary their speed through a low-voltage control signal rather than by reducing their mains supply voltage. The EFC-1 provides the interface between the TrolMaster controller and this variable-speed input, allowing fan output to be automatically adjusted as ventilation requirements change.
The EFC-1 can be configured for either PWM or 0-10V operation, making it suitable for a wide range of compatible EC ventilation fans. The fan retains its normal electrical supply while the EFC-1 manages the separate low-voltage speed-control signal.
On the TrolMaster Tent-X TCS-1, two EFC-1 adapters can be used, providing separate control of an exhaust fan and an intake fan. The EFC-1 is also supported by TrolMaster's Green-X GCS-1 greenhouse control system, where up to four standard EC fans can be independently connected through EFC-1 adapters.
Why choose the TrolMaster EFC-1?
- Variable EC fan control - automatically adjusts the speed of compatible electronically commutated ventilation fans.
- PWM & 0-10V compatibility - select the appropriate output mode to match the control input of the connected EC fan.
- Automatic ventilation management - allows fan output to respond to the settings configured within the compatible TrolMaster controller.
- Separate intake & extraction control - Tent-X supports one EFC-1 for exhaust and another for intake ventilation.
- Green-X compatible - the GCS-1 can independently control up to four standard EC fans using four EFC-1 adapters.
- Low-voltage speed control - controls the fan through its dedicated EC control input rather than regulating its mains supply.
- LCD display - provides local information and assists with setup and addressing.
- Addressable module - integrates into the TrolMaster device network as a dedicated fan-control interface.
- Plug-and-play design - designed for straightforward connection between compatible TrolMaster controllers and EC fans.
- RJ12 connection cable included - supplied with an RJ12-to-female-barrel connection cable.
What is an EC fan?
An EC fan uses an electronically commutated motor with integrated electronics to control motor operation. Many EC ventilation fans include a dedicated low-voltage speed-control connection that accepts either a 0-10V or PWM signal.
This allows fan speed to be varied electronically without repeatedly switching the fan's mains supply or using a conventional AC voltage-reducing speed controller.
The EFC-1 takes advantage of this control input, allowing a compatible TrolMaster system to request the fan speed required for the current environmental conditions.
PWM & 0-10V fan control
EC fan manufacturers use different low-voltage control methods. The EFC-1 supports the two common control types used by standard EC ventilation fans:
0-10V control
With a compatible 0-10V EC fan, the EFC-1 varies the analogue control voltage sent to the fan. The fan's electronics interpret that signal and adjust motor speed accordingly.
PWM control
For compatible PWM-controlled fans, the EFC-1 provides a pulse-width modulation control signal. The adapter must be configured for the appropriate mode to match the fan being connected.
Always confirm whether the fan requires PWM or 0-10V control before configuration. The fact that a fan uses an EC motor does not automatically confirm its control protocol or connector arrangement.
Intake & extraction control with Tent-X
The TrolMaster Tent-X TCS-1 supports up to two EFC-1 EC Fan Control Adapters. These are automatically assigned to the two dedicated ventilation functions:
| F1 | Exhaust / extraction fan |
|---|---|
| F2 | Intake fan |
Each ventilation line requires its own EFC-1. This allows intake and extraction airflow to be controlled separately rather than operating both fans from a single speed signal.
By varying fan speed rather than simply switching ventilation fully on or off, a compatible control system can provide smoother and more responsive airflow management.
Green-X EC fan control
The EFC-1 is also supported by the TrolMaster Green-X GCS-1 greenhouse controller. The GCS-1 can control up to four standard EC fans, with each fan connected through its own EFC-1 adapter.
This makes the adapter suitable for larger controlled horticultural environments where several independently managed ventilation fans are required.
TrolMaster Aero-Fan models use their own direct communication method and do not require an EFC-1 when connected to a compatible Green-X controller.
How the EFC-1 connects
The EFC-1 connects to the compatible TrolMaster controller through the controller's device network. The opposite side of the adapter connects to the compatible EC fan's low-voltage speed-control input.
A fan's main electrical supply remains separate. The EFC-1 is a control-signal adapter and does not provide mains operating power to the fan.
The EFC-1 package includes an RJ12-to-female-barrel cable. The exact connection required at the fan depends on the fan manufacturer's control interface, so its wiring and control specifications should be checked before installation.
Check EC fan compatibility
The EFC-1 is designed for standard variable-speed EC fans that accept a compatible PWM or 0-10V low-voltage control signal.
It is not a universal speed controller for conventional AC induction fans. Fans designed to have their mains voltage varied require a different type of controller.
Before installation, confirm the fan's control protocol, control-voltage requirements and connector or terminal arrangement. Where necessary, refer to the fan manufacturer's wiring information before making the control connection.

TrolMaster EFC-1 EC Fan Control Adapter FAQs
What types of fan control does the EFC-1 support?
The EFC-1 supports compatible EC fans using PWM or 0-10V variable-speed control. The appropriate mode is selected to suit the connected fan.
Can the EFC-1 control any EC fan?
No. The fan must provide a compatible PWM or 0-10V low-voltage speed-control input. Always check the specifications of the exact fan before installation.
Can the EFC-1 control a normal AC fan?
Not if the fan requires its mains supply voltage or frequency to be varied for speed control. The EFC-1 is intended for EC fans with a compatible low-voltage control input.
Does the EFC-1 power the fan?
No. The EC fan retains its normal electrical supply. The EFC-1 controls the separate low-voltage signal that tells the fan's integrated electronics what speed to operate at.
What is 0-10V EC fan control?
A compatible EC fan interprets a variable low-voltage analogue signal to determine its required speed. The EFC-1 generates the appropriate control signal under instruction from the TrolMaster controller.
What is PWM fan control?
PWM stands for pulse-width modulation. A compatible fan uses the characteristics of a pulsed control signal to determine the requested operating speed.
Can the Tent-X control both intake and extraction fans?
Yes. The Tent-X TCS-1 supports up to two EFC-1 adapters. One is assigned as F1 for the exhaust fan and the second as F2 for the intake fan.
Do I need two EFC-1 adapters for intake and extraction?
Yes. Each independently controlled standard EC fan line requires its own EFC-1, so separate intake and exhaust control requires two adapters.
Can the EFC-1 be used with Green-X?
Yes. The Green-X GCS-1 supports up to four EFC-1 adapters, allowing up to four standard compatible EC fans to be independently controlled.
Do TrolMaster Aero-Fans require an EFC-1?
Not when they are being used with a compatible controller that supports direct Aero-Fan communication. For example, the Green-X GCS-1 can communicate directly with Aero-Fans without an EFC-1 adapter.
Why use variable-speed ventilation instead of simple on/off control?
Variable-speed control allows airflow to be adjusted to suit current requirements instead of repeatedly operating the fan at full output. This provides more flexible ventilation management when used with a compatible control system.
What cable is supplied with the EFC-1?
TrolMaster supplies the EFC-1 with an RJ12-to-female-barrel connection cable. The connection required at the fan itself depends on the specific fan model.
How do I know whether my fan uses PWM or 0-10V?
Check the fan manufacturer's technical specifications or wiring diagram. The EFC-1 must be configured to match the control method required by the connected fan.
