Wiring a timer extractor fan without a switched live involves connecting the fan to a timer switch, which will automatically turn the fan on and off at predetermined intervals, regardless of whether the light switch is on or off. It is commonly used in bathrooms or other areas where ventilation is required intermittently or for a set duration after the light has been switched off.
This method of wiring offers several benefits. Firstly, it ensures that the extractor fan operates independently of the light, providing continuous ventilation even when the light is turned off. This helps prevent moisture buildup and unpleasant odors and improves indoor air quality. Secondly, it eliminates the need for a separate switched live wire, simplifying the wiring process and reducing the number of cables required. Lastly, it allows for greater flexibility in controlling the fan’s operation, as the timer switch can be set to specific intervals to match the ventilation needs of the space.
To wire a timer extractor fan without a switched live, follow these steps:
- Turn off the power supply at the main fuse box.
- Connect the live wire (usually brown) from the mains supply to the terminal marked “L” on the timer switch.
- Connect the neutral wire (usually blue) from the mains supply to the terminal marked “N” on the timer switch.
- Connect the live wire from the extractor fan to the terminal marked “Live Out” or “Fan” on the timer switch.
- Connect the neutral wire from the extractor fan to the terminal marked “Neutral Out” or “Fan Neutral” on the timer switch.
- Set the timer switch to the desired intervals.
- Turn on the power supply at the main fuse box.
Test the operation of the timer extractor fan by turning the light switch on and off. The fan should operate according to the set timer intervals, regardless of the light switch position.
