Watlow EZ-ZONE PM PID - Manual (Page 87)

Watlow EZ-ZONE ® PM PID Controller • 84 • Chapter 9 Features
Changing PM PID Model Number to PM Express
EZ-ZONE PM firmware revisions of 13 and above allow the user to switch between a PM PID control to a PM
Express. Switching to a PM Express eliminates the complexity of the PM PID control by allowing the user to
operate with a simplified menu structure.
Note:
When switching from an integrated control to an Express version, optional PM hardware (even though in-
stalled) and firmware features not available in a PM Express will no longer work. To see exactly what is
impacted by this change, compare the chart below to the ordering information page in this document.
