It sounds exactly like those fan units fitted as ventilators in bathrooms --- On Mon, 12/11/12, ravimiranda <ravimiranda@yahoo.com> wrote: I am searching for a power-off delay circuit that works as follows 1. Switch-on activates the equipment and a fan 2. Switch-off switches off the equipment 3. Fan remains on for 2-5 minutes (configurable??) Used for AC mains (230VAC), switch will be the usual on/off electrical power switch.
