3. Product Overview
The Suncourt Variable Speed Fan Controller features a simple design for ease of use. It includes a rotary dial for speed adjustment and an integrated outlet for connecting your fan.

Figure 1: Suncourt Variable Speed Fan Controller. This image displays the Suncourt Variable Speed Fan Controller. It features a prominent rotary dial for speed adjustment, labeled 'OFF' and with an arrow pointing towards 'LOW'. Below the dial, the text 'DIAL-A-TEMP' is visible. At the bottom, a standard electrical outlet is integrated for connecting a fan.
- Rotary Dial: Used to turn the fan on/off and adjust its speed from low to high.
- Power Outlet: Where the corded in-line duct fan is plugged in.
4. Setup
- Ensure the Suncourt Variable Speed Fan Controller is in the "OFF" position by rotating the dial counter-clockwise until it clicks.
- Plug your Suncourt corded in-line duct fan into the power outlet located at the bottom of the controller.
- Plug the Suncourt Variable Speed Fan Controller into a standard 120-Volt electrical wall outlet.
5. Operating Instructions
To operate the fan controller:
- With the fan plugged into the controller and the controller plugged into a wall outlet, rotate the dial clockwise from the "OFF" position.
- Continue rotating the dial clockwise to increase the fan speed. The fan speed will increase as you turn the dial towards the "HIGH" setting (implied by "LOW" marking).
- Rotate the dial counter-clockwise to decrease the fan speed.
- To turn the fan off, rotate the dial fully counter-clockwise until it clicks into the "OFF" position.
Note: Some fans may produce a buzzing sound at lower speeds. This is a characteristic of some motor types when used with solid-state speed controllers and does not necessarily indicate a malfunction of the controller.
6. Maintenance
- Ensure the controller is unplugged from the wall outlet before cleaning.
- Wipe the exterior of the controller with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Do not allow liquids to enter the controller's housing or outlet.
