This delayed off timer activates the exhaust fan in the bathroom or toilet when the light is switched on. After the light is switched off, the exhaust fan remains active during 2 to 10 minutes. After this time, the fan stops. The delayed off time can be adjusted via a trimmer. VTR-1 series are very compact and easy to install.
