User Interface
The KE2 Low temp’s onboard user interface uses the familiar 4- but-
ton arrangement to simplify navigation through the controller’s
menus.
To provide the most pleasant user experience, the menu structure
has been split into 2 groups: Basic and Advanced.
Basic Menu
For the majority of users, the Basic menu will provide the necessary
parameters to setup the controller.
The table Setpoints – Basic Menu provides a listing of the abbrevia-
tions for the controller. A more in-depth description of each is found
in the Abbreviations - Alphabetical Listing, on pages 19 -20.
Advanced Menu
Some users will require more complex congurations to achieve the
desired product performance. These more in-depth applications re-
quire additional parameters found under the Advanced Menu.
The table Setpoints – Advanced Menu provides a listing of the ab-
breviations and descriptions of available options. A more in-depth
description of each is found in the Abbreviations - Alphabetical List-
ing, on pages 19 -20.
