Low Consumer Cost and Installation

In most cases, PoolBoy can install the TightWatt timer directly into your existing enclosure. This reduces labor cost and also saves the cost of buying a new enclosure. The TightWatt control is generally less expencsive than other digital controls on the market, even though it has considerable greater efficiency. The pool timer has been designed to snap into existing Intermatic enclosures (the most popular enclosure on the market), dramatically reducing installation time. Installation of the controller into an existing enclosure takes just a couple of minutes. A new installation may take up to an hour depending on equipment configuration.

Automatic Cycle Operation

The TightWatt is an intelligent year-round control for a pool system. It is designed to take advantage of the seasonal temperature variation which allows a pool filter to run less during colder months and still maintain water quality. The user sets 2 time durations (summer run, winter run). The TightWatt then uses these values to compute a year-round run schedule. Some pool professionals adjust the pump run-time twice a year (once in spring, once in fall). Relieving the consumer/pool maintenance person of the task of manually adjusting a 24-hour timer (if it is adjusted at all) produces significant electrical savings over the course of a year.

Manual Cycle Operation

The user has the option to run a manual cycle for a specified duration. The manual cycle will only run once. Following the manual cycle, the controller will revert to automatic cycles each day.

Time of Use

The TightWatt allows up to 2 start times per day, and start times are set by the user. This flexibility allows it to work well with most time-of-use plans. Default settings of the controller cause the pool equipment to run at night in an effort to shift the load from daytime hours.
