What's the difference between PM PLUS® and PM LEGACY®?
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.
What are PM LEGACY® temperature controllers?
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.
