It continues to run until the condensation is cleared and the run-on time has elapsed. The fan can also be operated in conjunction with the room light switch. When the light is switched on, the fan will run on and continue to run for a pre-set time after the light is switched off. The fan should be left switched on with a constant power supply connected at all times. Additionally, it requires permanent live, switched live, and neutral (3 wires excluding earth) connections if the timer via light switch functionality is required. This fan is normally used in bathroom or toilet locations.
