The OSSMD-FT is a Leviton exclusive model which also provides automatic switching of two separate loads from a single unit. The unit features a single manual override switch for the first relay. The second, "fan relay", is an auto-on with relay 1 and has an extended time delay of 10 minutes after relay 1. This provides both energy efficiency and optimum ventilation control from a single device.
