Product Overview
The Intermatic P1131 provides a durable and cost-effective solution for automating outdoor equipment such as above-ground pool pumps, holiday lighting, or decorative water features. Simply plug the timer into a standard outdoor outlet (or twist-lock receptacle variant), plug in the equipment, set the dial to the current time, and position the ON/OFF trippers to schedule the load’s cycle. Because the timer uses a mechanical dial rather than a complex electronic interface, it is user-friendly and easy to service or adjust without specialized tools.

With weatherproof housing and a design targeted at above-ground pool equipment, this model is especially suitable for pool-service professionals and retail catalogs targeting residential installers. It supports motor loads up to 1 HP at 120 V (motor rating) and is built for outdoor durability and ease of setup. When listing this item in your e-commerce catalog, emphasize its reliability, outdoor-rated construction, simple programming, and suitability for energy-control in pool pump or lighting applications.
