Description

Rheem 42-41870-82 Time Delay Relay – 0.83 min. Make Time, 1.67 min. Break Time, 18-30 VAC replaces 42-41870-02, 42-42141-01, 42-42146-01, 42-42146-81, 8201-5599.Power must be applied before and during the time delay period. When the initiate contact closes, the delay on make period begins. The load then energizes and remains energized as long as the initiate contact is closed. The delay on break period begins when the initiate contact opens. At the end of the time delay, the load is turned off. If the initiate contact recloses during the time delay, the load remains energized and the time delay is reset to zero. Removal of input power during the delay turns off the load and resets the time delay to zero. Common applications include control of the blower during heating/cooling cycles to let air reach proper temperature before turning on the blower, and to purge ducts of residual condition air.
