DC Fans usually cost more, while there are quite a few DC models on the market, at the time of writing this most DC fans started at $300 and up. DC Fans cannot be controlled by the traditional 3 speed wall control, they must have a remote control which talks to the electronic in the fan to change the speed of the fan.
All ceiling fans need a wall switch, regardless of it having a remote control or not. Thus, because the ceiling fan would already be connected to a wall switch, you don't need an additional wall switch to operate the ceiling fan once you've added the remote control and receiver, as it gets connected to the fan itself.
1 Answer 1 There's no problem installing the fan without a switch. In many cases folks replace a switched ceiling light fixture with a fan, so the fan uses the switch that used to control the light. In other cases the ceiling is too high, so controlling the fan via the pull chain is inconvenient.
DC ceiling fans – All DC ceiling fans are remote controlled only which means that they all come with a remote included and cannot be controlled by a wall control or pull cord.
This is a mandatory requirement when having your ceiling fan(s) fitted. An isolation switch looks like a light switch on the wall that needs to be in the 'on' position in order to operate your fan via the remote control (if you have a remote).
Many modern ceiling fans offer remote control switches. They don't require installation like a wall switch, but you'll still need to install the ceiling box. Remote controls generally use batteries, so you just need to ensure you have a backup supply.
An isolator switch is usually used in situations where there is a risk of electric shocks, such as damp conditions. When the switch is in the “off” position, it creates a break in the circuit that prevents the current from flowing. This allows you to work safely on the circuit without the risk of electrocution.
They come with standard wiring and can be connected to a standard wall switch, so you don't need any special wiring or controls.
DC fans, though more expensive initially, offer long-term savings through reduced energy use. This makes them an ideal investment for those looking to minimise their environmental impact and lower electricity bills in the long run.
Nearly all ceiling fans have a switch located on the side of the fan base that lets you change the direction of the fan blades. Why? Setting the direction of your fan blades will help you control the temperature in your home, so you can save on both cooling and heating costs.
You can just cap the red wire with a small wire nut and ignore the switch on the wall. Pull and twist and the wires will likely pop out (the reason backstabs like this are not reliable). If they're torn up or won't come out then snip and restrip.
If your fan is not getting power, you have a wiring issue that must be repaired. Wiring between the switch or power source and fan has likely gone bad.
Wiring a Fan or Light Without Switches
This method means that you would use the pull chains included with your fan to turn on the light and the fan. For rooms without switches, ceiling fan remotes can alleviate the need of using a pull chain. Connect the white wires (neutral wires) from your fan and ceiling together.
However, the major disadvantage is that the remote control is portable, which raises the danger of misplacing or destroying the remote. Furthermore, most of these remotes are battery-powered, which adds to the expense. Furthermore, these systems are more expensive than a standard fan and require additional maintenance.
Disadvantages of DC Ceiling Fans
DC ceiling fans tend to be more expensive to purchase, although, this cost has come down significantly with improvements to technology and manufacturing. Even being more energy efficient, it could take a long time for you to see the pay-off of buying a DC fan.
Higher Cost: DC ceiling fans are generally more expensive upfront than AC fans due to their advanced technology and capabilities. Complexity: The advanced motor and electronics can make DC fans more complex to repair if they malfunction.
Four-blade fans offer a balance between airflow and noise reduction. They are versatile, suitable for various room sizes and styles, and quieter than three-blade fans while still providing decent airflow. On the downside, they are slightly more expensive than three-blade fans and may not move as much air.
All fans with a remote control should be installed with an isolation switch, which can and often will be an on/off switch somewhere in the room. This switch is used to supply power to the fan and light and is required for safety reasons.
Brushless DC motors have 3 wires because they typically have 3-phase windings inside the motor. These 3 phases are used to control the rotation of the motor and generate a magnetic field to make the motor turn. The 3 wires provide a connection to each of these phases, allowing them to be powered and controlled.
DC ceiling fans offer better speed control, usually with more speed settings than AC fans. This allows you to fine-tune the airflow to your preference, providing just the right amount of breeze for any situation. The precise control over fan speed enhances comfort and efficiency.
To do this you require a switched live, to trigger the fan to switch on, and a permanent live that stays live, to run the extractor fan. A fan isolator switch enables this functionality, and also enable the ability to switch off both the switch live and permanent live off, making it safe within the bathroom.
Fitting this without any other work being done costs £158.25, or £325 if you have a 3-phase supply. Call us for more info and to book this in for a Monday-Friday appointment at least 17 working days in advance. You can call the team on: 0330 303 5063. Our opening hours are 8am-6pm Monday to Friday.
An isolation switch (or isolator switch) is a piece of equipment that is installed on a metering supply to allow that supply to be de-energised after your meter. It normally sits inside your meter box and it sits after the meter but before the consumer unit.
