Conventional fans are controlled either by buttons and regulators present on wall panels or pull chains. However, in modern times, advanced ceiling fans controlled by remotes are also available widely in the market. Both infrared and radio frequency remote controls are used for ceiling fans. However, radiofrequency or RF remote controls are more popular because they don’t need a direct line of sight and can be pointed anywhere in the room to control the fan. Remote-controlled ceiling fans come with two components. One is the transmitter or receiver which sends the signals, and the other is the receiver which is present on the canopy near the ceiling.
Some major features of a ceiling fan with remote have been discussed here.
AC and DC Remote Controls
DC remote control is newer than the AC remote control. In case of a ceiling fan run by DC remote control, drivers are present on the fan which convert the AC input voltage into DC, process the control as per the signal from the remote and reconvert the DC to AC to power the fan’s motor. AC remote controlled ceiling fan, on the other hand, has capacitors to start and control it.
AC remote controls provide 6-speed settings while DC remote controls provide 3-speed settings. It must be noted that DC ceiling fans can be controlled by remote controls only because they are not compatible with wall panels and pull cords.
Radio Frequency and Infrared
Radio Frequency remote control is not required to be pointed at the ceiling fan to operate it. Multiple ceiling fans in the same house with each one having its own RF remote don’t interfere with one another. Multiple ceiling fans can also be switched on and controlled together by setting all of them at the same frequency.
The infrared remote control must be pointed towards the fan to control it. This is because infrared must have a clear line of sight to the fan. Multiple infrared controlled ceiling fans installed in the same house can interfere with the working of one another. One IR remote cannot be set to control multiple ceiling fans.
The remote control has a button for switching the fan on and off. Buttons are also present for controlling the speed of the ceiling fan. 3 or more speed settings are usually present. For a ceiling fan with light, on/off switch for the light is also present. Many models also have dimmers on their remotes to control the brightness of the lights. The light switch can also be completely separated from the remote and mounted on a wall panel. The timer is another function present in the remote controls of many advanced ceiling fans. Some models are also equipped with a reverse function to change the direction of rotation.
Remote-controlled ceiling fans come with wall brackets. A wall bracket enables the user to mount the remote on the wall when not in use. It prevents the remote from getting misplaced.
Remote-controlled ceiling fans cost more than regular ceiling fans, but the ease of usage provided by a remote is considered worth the cost.
