Forward and reverse function

Many, though not all ceiling fans are controlled with so-called pull cords. Usually they are already included in basic models. The fan speed and if applicable, the light is activated by a light pull. Some models, in particular commercially used fans, are installed without the cords for aesthetic reasons. Another motive for going without pull cords is a tall ceiling where the strings are simply impractical and hard to reach without stepping on a ladder. In that case it is recommended to opt for a remote control or wall control instead.

Once you have decided in favour of a model, it is necessary to find the optimal rotation speed. On cold days other factors have to be considered when using the reversing feature that when the fan moves in summer mode.

PS: Whether the ceiling fan’s winter mode is clockwise or anticlockwise, depends on the manufacturer. However, there is a way to find out which mode the fan is currently adjusted: Position yourself directly under the ceiling fan. If a noticeable airflow is coming down on you directly from above, the ceiling fan is operating in summer mode. If the airflow has more of a sideways movement along the ceiling and the walls of the room, it is in reverse.

Operation in the winter

Operation in the summer

On hot summer days owners are able to enjoy the entire spectrum of rotation speeds of a ceiling fan. During the day you counter hot temperatures on medium or high speed and benefit from the lowest setting during the night. The fan operates so quietly that your sleep will not be disturbed by noise.

The generated airflow meets our skin and gives a pleasant and cool sensation. That is why it is so important to have the option to individually adjust the ceiling fan to prevent a cooling effect that is too strong. Often radio or infrared remote controls are utilised simply because they offer great convenience, allowing you to select the required setting in a fast, effortless manner. Of course, these adjustments can also be made by using a pull cord or wall controller instead.

In summary it can be said that the rotation speeds are changed more often in the summer than in the winter. If you are sensitive to sudden changes in temperature it is better to opt for a fan with six instead of three speeds. This gives you more room to fine-tune the operation of your fan. Often you will find that basic models can be upgraded with controller units if required.

Overview of controllers

Start, standby, lighting e.g. intensitiy and colour, fan speed and direction of the motor are features most modern ceiling fans are equipped with. Basic configurations can be done directly on the device with pull cords or switches. As the fan is mounted outside of reach, external controllers are a handy solution. By implementing sensor TDA technology, step transformers or continuously variable controllers you can regulate several fans at once, for example in storage buildings.

⮩ Fans are rarely supplied without any type of control. Whether you require any additional control systems or not is always stated in the item description. If you have a universal remote control it is cheaper to buy a second fan without controller. Otherwise it makes sense to always included a control in your order.

The CasaFan Slow Motion Module reduces the speed of fans to about 45 revolutions per minute which equals an extremely slow and quiet operation. By comparison: Usually speeds of AC fans range from 90 to 250 rpm. The curbed operation is useful if the ceiling fan only offers a small amount of possible fan speeds. The motor of the fan is not affected by the external controller. However the module is not suitable for direct current models. As the energy-saving DC models come with up six speeds anyway, it is also not needed.

The quantity of the fan blades impacts the volume of transported air. The energy-saving Turno for example can be installed with three, four or five blades down to your whim. Another important factor for the airflow is the pitch and shape of the blades. Give it a “whirl” and see what works best for you and your environment.

Hazards of draught

Summary

Pull cords, wall controls, remote controls and step transformers are all suitable for the regulation of ceiling fans. Transformers add even more levels to the device. Control systems in professional environments offer synchronized operation of several fans at once. Remote controls are generally very practical as they allow users to select all settings from the comfort of their couch. Both during the summer and winter mode it is important to fine-tune the airflow. Draught can affect the health and is harmful for the well-being. By utilising an appropriate controller you can optimise the airflow. An automatic timer is best for the bedroom.
