Frequently Asked Questions

How does this (W3CAT4000WIFI) differ from the CAT-4000-WIFI?

Both are CAT 4000 WiFi Standard Packages with pH and ORP sensors and PoolComm connectivity. The W3CAT4000WIFI is the pool equipment channel version with NSF/ANSI Standard 50 certification explicitly listed, and ships with slightly larger dimensions. Both carry the 5-year controller warranty. If your project specification requires NSF/ANSI Standard 50 certification documentation, the W3CAT4000WIFI is the appropriate model.

What is PoolComm?

PoolComm is Hayward's cloud-based commercial pool monitoring platform. WiFi access to PoolComm is free for CAT 4000 users — it allows monitoring and management of water chemistry readings remotely via web browser or mobile device.

Does this include a flow cell and flow sensor?

The Standard Package includes the pH and ORP sensors and WiFi transceiver. For the version with machined flow cell and rotary flow sensor included, see the CAT 4000 Professional Package (CATPP4000WIFI).
