Seasonal timer mechanisms manage multiple circuits for pool and spa equipment that need scheduled operation throughout the year. The Intermatic Seasonal Timer Mechanism [4 Circuit] [115V/230V] (P1403ME) is a replacement timing mechanism for compatible Intermatic controls requiring four-circuit scheduling with 115 volt or 230 volt equipment support. This mechanism is useful when the timer no longer advances, switching becomes unreliable, trippers fail to operate correctly, or the original mechanism is damaged while the enclosure can still be reused. Replacing the internal mechanism can restore automated scheduling without replacing the entire control enclosure, saving labor and keeping the equipment pad organized. Four-circuit seasonal timer mechanism Supports 115V and 230V applications Useful for pool and spa equipment scheduling Can restore function without replacing the enclosure Ideal for Intermatic timer repair service
