The PM LEGACY® is ideal for basic heating and cooling applications.

The LEGACY® includes one universal input and an option for up to two outputs and is available in 1/16 DIN and 1/32 DIN panel mount packages. It can be ordered as a PID process controller or as a dedicated over and under-temperature limit controller.

The PM PLUS® is is backwards compatible with LEGACY®, but offers much more. For example, PM PLUS® offers Bluetooth® connectivity with the EZ-LINK™ mobile app for remote access capability with full descriptions of parameters and error codes

The PM PLUS® improves the user experience by reducing the complexity at the front of the control while eliminating the dependency of cables when configuring the product. Like the original EZ-ZONE® PM, the PM PLUS® can be ordered as a PID controller, or an integrated controller with multiple functions combined into one.

Watlow’s new PM LEGACY® temperature controllers utilize the EZ-ZONE® PM platform by optimizing performance through simple control and menu functionality without complex features. They are ideally suited for basic applications and usage levels. PM LEGACY® controllers can be ordered as PID process controllers or as dedicated over and under-temperature limit controllers.

In short, the main differences between FDA approved, food-grade, and NSF-certified are as follows: FDA approved: Primarily applies to drugs, medical devices, and certain food additives; indicates that the FDA has approved the product for a specific intended use. Food-grade: Refers to materials and substances safe for direct contact with food; ensures they meet regulatory standards for food safety and prevent contamination. NSF-certified: A certification provided by NSF International, typically related to equipment and materials used in the food industry; indicates that the product meets specific safety, quality, and performance standards set by NSF.
