Temperaure Compensation does two things:
Adjust the output higher when temps get warmer - keeps your chlorine level ahead of the demand so you don't get any algae.
Adjust the output lower when temps get cooler - reduces chlorine levels from damagingly high levels. Also, improves cell life by not operating the cell too much under cold water conditions, yet not shutting the cell off (due to cold water cut off).
This occurs without any input from the pool owner.
The others require manual testing and adjustment of the system as seasonal temperatures change.
Pool Pilot provides the salt addition amounts on the Digital display. We've realized that not maintaining the salt level has been a problem, and as a result we've made it easier for the pool owner to see how much salt is needed to maintain proper levels. The Digital calculates and shows you how much pounds of salt are needed to maintain 3000 ppm, based upon the initial programming of your pool volume.
The others require that you find your manual, refer to the salt addition chart, and calculate how much salt is needed.
Pool Pilot provides a patented manifold assembly. This aids in the efficiency of the chlorine generation process by slowing down the flow through the cell. The result of the slower flow is more contact time of the "stuff" in the water within the cell so that it gets the "shock" treatment more effectively.
Pool Pilot provides a 24 hr or 72 hr boost mode. In addition, if the Digital is used to control the main filter pump, the BOOST mode will override the pump control and run for the duration of boost time. If it is not controlling the pump, the boost mode, remaining hours, are retained in memory so that when the pump resumes operation the following day(s), the Pool Pilot knows how many hours are remaining in the boost cycle.
Pool Pilot allows you to upgrade the cell at any time. The Digital Control box can operate with either of the three model residential cells, without any other modifications or components, other than adjusting the Purifier % level.
Pool Pilot does not have a high salt limit. Although the normal operating range is 2500 - 3500 ppm, a high salt condition will not shut down the operation of the Pool Pilot. Other systems can be deceived into "reading" a high salt level and shut down from the initial salt dosage, or a rapid increase in water temperature such as when the spa heater/solar panels are activated.
High salt shut down due to oversalting requires draining to dilute the salt level.
