Controller Operation
Figure 1 – Basic Controller Home Screen
This is the default operating screen display after
power is applied and the controller has gone
through its initial start-up. It is also the screen that
displays after exiting one of the submenus.
The temperature control unit includes a controller to
perform all control functions directly from the front
panel. When power is applied to the unit, the
controller lights up and “Loading . . .” appears on the
display for a few seconds while the controller boots
up. The controller then displays the software version
followed by a display of temperatures.
Soft Buttons
There are three buttons under the display. The
function of these button changes depending on

The increase button is used to raise the temperature
and for selecting items in various menus.
Enter Button
The enter button is used to confirm a temperature or
parameter adjustment in various menus.
Decrease Button
The decrease button is used to lower the
temperature and for selecting items in various
menus.
