Frequently Asked Questions
What is the EZ-LINK™ mobile application?

EZ-ZONE® PM controllers that are equipped with Bluetooth® wireless technology.

soon.
Why would I want to use the app?
• The EZ-LINK mobile app makes navigating the controller’s menus easier because it uses the same methods for locating and
viewing items that you are used to in the other apps you already use on your device.
• The app makes understanding the prompts or parameters much easier because it spells out the names in plain language,
which is much easier to read than the cryptic, four-character, seven-segment display. Also the app provides help for each
parameter with short, simple explanations.
• If your controller is in a dicult to reach spot, using the app can make it a lot easier to make adjustments to the process.

ELZK-FAQ-0418
How do I change the temperature units?
• The iOS (Apple®) version uses the same temperature units setting that the controller display uses. You can change
this with the display units parameter on the global menu in the all parameters screen.
• In the Android™ version, nd the temperature units parameter on the device settings view accessed by tapping the
gear (settings) icon on the device view. This setting is independent of the display units setting for the controller, which is
available on the global menu in the all parameters screen.
Does the app support ramp and soak proling?
• You can set up the feature with the proling-related parameters on the global menu in the all parameters view.
• You can operate proling with the home page on the dashboard.
• The initial version of the app supports access to the parameters on the controller’s home and setup pages and the factory
page, diagnostics menu, but not the prole page. Therefore, currently you cannot program proles with the app.
Can I save the controller’s settings using the app?
• On the all parameters view, in the global menu, the save settings as parameter saves the controller settings in the
controller’s memory.
• There is no way to save the controller’s settings in your phone or mobile device at this time, but it is a feature we expect will
be available in the future.
What if I want to limit the parameters users can access?
• Use the write security parameter on the factory page’s lock menu in the EZ-ZONE PM to have the app present parameters
as read-only.
• Set write security to 0 to make the parameters on the home page read-only.
• Choose which parameters appear on the dashboard using the factory page, custom home page menu in the EZ-ZONE PM.
Using COMPOSER® software you can put practically any parameter on the controller’s home page, which the app shows on
its dashboard.
• On the factory page’s lock menu in the EZ-ZONE PM set locked access level to 3 or less and set password enable to on to
prevent access to the all parameters menus in the app. This also prevents access to the setup page in the controller. Enter
the password on the controller to access these features in the controller and in the app.
• Turn o Bluetooth® communications on the setup page, global menu if you want to prevent the controller from being
available to connect to the app altogether.
• When the controller powers up, it displays the rmware version, then whether Bluetooth® (btth) communications is enabled
(on) or not (o).
How close do I have to be to connect with a controller?
• The app can connect with EZ-ZONE PM controllers up to 70 feet (21 meters) away under ideal conditions. Depending on the
environment and obstructions you may nd you need to be closer.
What if the app does not nd my controller?
• Try walking closer to the controller.
• Make sure the controller has the Bluetooth® option.
• Make sure Bluetooth® is turned on. When the controller powers up it momentarily displays the message, “on btth” or
“oFF btth” immediately after showing the rmware version. Turn it on or o at the “btth” prompt on the controller’s setup
page, global menu.
• Check if anyone else is already connected. The controller can only pair with one phone or mobile device at a time.
When there is more than one controller in range, how do I tell which one is communicating with
the app?
• Use the app’s ping feature to have the controller’s display indicate it is connected or about to connect. The “ping” button
appears on each item in the list of available devices before you connect and on the device screen after you connect to a
controller.
• Give each controller a unique name to make it easy to nd the next time.
If I connect to the wrong EZ-ZONE PM, what do I do?
• Disconnect and choose another from the list of available controllers.
