Frequently Asked Questions
What is the difference between this (CATPP4000WIFI) and the Standard Package (CAT-4000-WIFI)?
Both are CAT 4000 WiFi controllers with the same PoolComm connectivity, alarms, and sensors. The Professional Package upgrades the flow measurement hardware to a machined acrylic flow cell and rotary flow sensor (RFS), which provide more precise and reliable flow detection compared to the molded cell and float sensor in the Standard Package. The Professional Package is also larger and heavier due to the additional hardware.
What is the advantage of a rotary flow sensor over a float-style sensor?
Rotary (paddle wheel) flow sensors provide more accurate and reliable flow detection across a wider range of flow rates and are less susceptible to scale buildup or debris compared to float-style sensors. They're the preferred choice in commercial applications where flow confirmation accuracy is critical for chemical dosing safety.
Does PoolComm require a subscription?
Per the product documentation, PoolComm access is free for CAT 4000 WiFi users. Confirm current PoolComm access terms directly with Hayward as these may change.
