## What is Watlow EZ?

Use EZ-LINK™ to easily set up, monitor and adjust Watlow® PM PLUS and EZ-ZONE® PM controllers via Bluetooth® wireless technology. The app provides access to the controller’s parameters with fully spelled out names in plain text with help topics that explain each parameter and option.

The app’s home page displays the same parameters as the controller’s custom home page. The “All Parameters” button allows you to set up the controller’s inputs, control settings, alarms, outputs and other features and functions.

Use the app to save the PM’s settings in a configuration image file. Import the image file into a controller to copy the configuration from one controller to another or to restore the configuration of a controller to an earlier state. You can also share the saved files via email or other file sharing methods. The files are compatible with Watlow’s COMPOSER software which can be used to view the settings on a PC.

EZ-LINK also provides password protection, alarm and error indicators, connection to Watlow for feedback and support and access to device information such as firmware version, part number and serial number.

The app works with all PM PLUS and 1/16 DIN EZ-ZONE PM controllers and limits with Bluetooth® wireless technology. This option is approved for use in the U.S., Australia, Canada, Columbia, the European Union, Japan, and New Zealand with more locations coming soon.

### 1/5 — Was fine till update

*2023-07-22*

This was fine and did what it needed to do. Then, it updated itself to version 4 and does not work at all. Nothing whatsoever, just complete junk now. Please undue this update so i can use my controllers.

### 2/5 — The old version was 5 stars

*2023-06-25*

The Bluetooth communication with the controllers is slow, the measured values lag behind. 

I used the old version, which was a bit more cumbersome, but it was fast and easy to work with. But as everything seems to be evolving these days, the appearance seems more important than functionality.

### 1/5 — Version 4.0 Extremely Slow

*2023-05-31*

Updated from v3 to v4 and app response is very slow when connected to PM Plus 6 controller. Takes up to a minute sometimes for buttons and values to update on app screen. Had no issues on v3

### 2/5 — App controls for PM Plus

*2021-12-07*

This app is very confusing and there is not a good manual to follow how to create and use profiles. It is not intuitive. 

One way this could have more stars would be if it had the capability to log and record the active process outputs over a profile run. Can you please update this app to include that?
