Frequently Asked Questions
What does "dual sanitizer support" mean in practice?
The 2-pump configuration allows a primary sanitizer source (such as a salt generator) to handle normal day-to-day chlorine production, while a secondary liquid chlorine feeder is available to kick in automatically when demand spikes — such as after heavy bather load or a rainfall event that dilutes the pool. The system monitors ORP and automatically activates the secondary pump to quickly restore chlorine to the set point.
How does this differ from the residential IntelliChem models (522621, 522622)?
The 522578 is the commercial-grade model with dual sanitizer pump support, ScreenLogic2 standalone remote included, and a 2-year warranty (vs. no warranty stated for the residential models in this category). The residential 522621 and 522622 are single-sanitizer models suited for home pools; the 522578 is designed for aquatic facilities with higher demand and the need for remote monitoring.
Is ScreenLogic2 monitoring included?
Yes. The ScreenLogic2 PC Interface is included in the box, allowing staff to monitor pH and ORP levels and make chemical adjustments remotely from a computer or device connected to the network.
Is it compatible with IntelliChlor salt generators?
Yes. The IntelliChem 522578 is fully compatible with IntelliChlor salt chlorine generators, making it suitable for commercial salt water pool installations where both automated pH control and dual sanitizer backup capability are needed.
