COMPOSER®

COMPOSER® is Watlow’s new, easy-to-use software for 

configuring and customizing controllers. Use it to optimize 

Watlow’s F4T®, D4T™ and EZ-ZONE® PM and RM 

controllers for specific applications. Task-specific views 

simplify all aspects of commissioning new controllers 

including managing the inputs and outputs from pluggable 

flex modules, setting up functions such as control loops 

and alarms and creating and editing profiles. COMPOSER 

software is included on the “Watlow Support Tools” DVD 

and available for download at www.watlow.com.

EZ-LINK™ Mobile App

Watlow’s EZ-LINK™ mobile app allows users to easily set 

up and monitor Watlow PM PLUS™ and EZ-ZONE PM 

controllers via Bluetooth® wireless technology. The app is 

available free-of-charge from the app stores for phones 

and tablets, and provides access to the controller’s 

parameters with fully spelled out names in plain text with 

help topics that explain each parameter and option.

When connected to a controller, the app’s dashboard 

view displays up to 20 parameters. Users can configure 

which parameters appear on the dashboard view with the

controller’s custom home page. The all parameters 

feature in the app allows users set up the controller’s 

inputs, control settings, alarms, outputs and other 

features and functions.

In addition to controller setup, monitoring and adjusting,

the EZ-LINK mobile app provides many benefits to the 

user including password protection, alarm and error 

indicators, connection to Watlow for feedback and 

support and accessing 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, Colombia, the European Union, Japan 

and New Zealand with more locations coming soon. 

Features and Benefits

Wireless communication

• Connect to controllers up to 70 feet (21.3 meters 

away)

• Eliminates need to access the back of the controller,
