4. Setup and Installation
This controller is designed for installation in a standard 2" x 4" electrical wall box.
- Power Disconnection: Before beginning any work, turn off the power to the circuit at the main electrical panel (circuit breaker or fuse box). Verify that the power is off using a voltage tester.
- Prepare Wall Box: Ensure the electrical wall box is clear and ready for installation.
- Wiring: Connect the controller's wires to the corresponding household wiring using the provided wire connectors. Refer to the wiring diagram typically found on the product packaging or included wiring sheet for specific connections (e.g., Line In, Load Out, Ground). Ensure all connections are tight and secure.
- Mounting: Carefully push the wired controller into the wall box. Secure it using the provided mounting screws.
- Install Dial Plate and Knob: Attach the dial plate over the controller, aligning it correctly. Then, firmly push the control knob onto the shaft.
- Restore Power: Once installation is complete and all connections are secure, restore power at the main electrical panel.
5. Operating Instructions
The FarmTek Manual Ceiling Fan Controller provides simple and effective speed adjustment for your connected devices.
- Power On/Off: The controller features an integrated on/off line switch. Rotate the knob fully counter-clockwise to the 'OFF' position to turn off the connected device. Rotate it clockwise from 'OFF' to turn the device on.
- Speed Control: Once the device is on, continue rotating the knob clockwise to increase the speed (towards 'HIGH') or counter-clockwise to decrease the speed (towards 'LOW'). The controller provides infinitely variable speed motor control, allowing for precise adjustment.
- Minimum Speed Trimpot: For advanced users, a minimum speed trimpot may be present on the unit (typically behind the dial plate or inside the enclosure). This allows for setting a minimum operational speed to prevent motor stalling at very low settings. Adjust only if necessary and with power disconnected.
- Rheostat Functionality: This controller can also be used as a rheostat for other compatible resistive loads, providing variable power output.
6. Maintenance
The FarmTek Manual Ceiling Fan Controller requires minimal maintenance.
- Cleaning: To clean the surface of the controller, wipe it with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the finish or internal components.
- Inspection: Periodically inspect the controller for any signs of damage, loose connections, or unusual operation. If any issues are observed, disconnect power and consult a qualified electrician.
- No User-Serviceable Parts: There are no user-serviceable parts inside the controller. Do not attempt to open or repair the unit yourself.
7. Troubleshooting
If you experience issues with your FarmTek Manual Ceiling Fan Controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller does not turn on or fan does not operate. | No power to the circuit. Loose wiring connection. Faulty controller. | Check circuit breaker/fuse. Verify all wire connections are secure (with power off). If power is present and connections are good, the controller may be faulty and require replacement. |
| Fan operates only at one speed or does not respond to knob adjustment. | Incorrect wiring. Controller incompatible with fan motor type. Internal fault in controller. | Review wiring diagram and re-wire if necessary (with power off). Ensure the fan motor is compatible with solid-state speed control. Replace controller if wiring and compatibility are confirmed. |
| Humming or buzzing noise from fan/controller. | Motor incompatibility. RFI filter issue. | Some motors may produce a slight hum with solid-state controls. If excessive, ensure motor is compatible. The controller includes an RFI filter to minimize interference. |
If troubleshooting steps do not resolve the issue, please contact FarmTek customer support or a qualified electrician.
