Control options explained...

To help better understand the control options available for Fantronix domestic extractor fans, please see descriptions below, along with some wiring suggestions and tips:

Extractor fan controlled on/off via a separate switch...

The on/off control option is basically live and neutral electrical connections to your fan (earth is not needed). As no switch is provided, you can simply wire to your own switch, plug or circuit.

  • Simple live & neutral connections.
  • Connect to your lighting or household electrical circuit to operate via your light switch, pull cord or separate switch.
  • Connect to a cable and household plug for portable use.
  • Connect to an electrical circuit to allow the cooling of equipment after switch off.

Extractor fan controlled by run-on timer...

The run-on timer control option requires live, neutral and switched live electrical connections to your fan (earth is not needed). The switched live connection is used to operate the run-on timer. The fan will continue to run after the switched live has been interrupted by your switch or pull cord. The run-on time can be adjusted inside the fan from between 2 and 30 minutes.

  • Live, neutral & switched live connections.
  • Connect to your lighting or household circuit to operate by your light switch, pull cord or separate switch.
  • Built-in run-on timer.
  • Connect to an electrical circuit to allow the cooling of equipment after switch off.
Tips
Building regulations state that if your room is enclosed with no opening windows, then a fan with a run-on timer must be used.

Extractor fan controlled by pull cord...

The pull cord control option is basically live and neutral electrical connections to your fan (earth is not needed). The fan can then simply be operated by its own built-in pull cord.

  • Simple live & neutral connections.
  • Connect to your lighting or household electrical circuit.
  • Connect to a cable and household plug for portable use.
  • Built-in pull cord.

Extractor fan controlled by humidity sensor & run-on timer...

The humidity sensor & run-on timer control option requires live, neutral and switched live electrical connections to the fan (earth is not needed). The switched live connection is used to operate the run-on timer. The fan will continue to run after the switched live has been interrupted by your switch or pull cord. The run-on time can be adjusted inside the fan to continue running from between 2 and 30 minutes. The fan will also switch on automatically and independently when humidity levels get high. The humidity level is also adjustable inside the fan to suit different environments.

  • Live, neutral & switched live connections.
  • Connect to your lighting or household circuit to operate by your light switch, pull cord or separate switch.
  • Connect to an electrical circuit to allow the cooling of equipment after switch off.
  • Automatically works when humidity levels change.
  • Built-in run-on timer.
Tips
Building regulations state that if your room is enclosed with no opening windows, then a fan with a run-on timer must be used. If you want the added option of automatic use when humidity gets high after a shower or bath, choose this control option.

Extractor fan controlled by pull cord & run-on timer...

The pull cord & run-on timer control option only requires live & neutral electrical connections to your fan (earth is not needed). The fan has its own built-in pull cord to switch the fan on or off. When switched off, the fan will continue to run for a preset period of time, this run-on time can be adjusted inside the fan from between 2 and 30 minutes.

  • Simple live & neutral connections.
  • Connect to your lighting or household circuit to operate by your light switch, pull cord or separate switch.
  • Built-in pull cord.
  • Connect to an electrical circuit to allow the cooling of equipment after switch off.
