Frequently Asked Questions
What is OmniX?
OmniX is Hayward's advanced pool automation platform. Embedded in this heater, it enables enhanced programmability, advanced diagnostics, and seamless remote connectivity. The Universal Display also ensures compatibility with standard Omni systems and competitive third-party automation platforms.
How does this differ from the standard H-Series 250K NG (H250FDN)?
The HS250FDN adds OmniX embedded intelligence and the Universal Display for remote connectivity, enhanced programmability, and advanced diagnostics — features not available on the standard H250FDN. Choose the HS250FDN if OmniX integration is required for your installation.
