Frequently Asked Questions
What is PoolComm and is there a subscription fee?
PoolComm is Hayward's cloud-based commercial pool monitoring platform. Per the product description, WiFi access to PoolComm is free for CAT 4000 users. Confirm current PoolComm access terms with Hayward directly, as these may change.
How does this compare to the CAT 2000 packages?
The CAT 4000 adds WiFi remote monitoring, PoolComm cloud connectivity, multi-format alarms (email/text/visual/audible), and a bright alphanumeric display vs. the LED display on the CAT 2000. Both share the same 5-year controller / 2-year sensor warranty and proportional feed technology. Choose the CAT 4000 WiFi when remote monitoring and alarm notifications are required; choose the CAT 2000 for on-site-only control.
What alarm types are available?
The CAT 4000 supports email alerts, text message (SMS) alerts, visual on-screen alarms, and audible alarms for out-of-range pH, ORP, and flow conditions. This means staff can be notified immediately when water chemistry requires attention — even when away from the facility.
