NAVIGATING THE CONTROL
The four large red buttons labeled “A”,
“B”, “C”, and “D” are used to make
your way through the programming
options within the Control.
Pressing the “A” or “B” button while
viewing the initial “System Status” and
“System Function” main screens will
toggle from screen to screen. Pressing
the “D” button will take you to the
“Programming Options” screen.
Pressing the “D” button again will
revert to the main system screens.
Once in the “Programming Options” menu you may move the selection indicator up and down by pressing the “A”
and “B” buttons, pressing the “C” button will enter the selected option.
Pressing the “C” button on options with limited choices (ie. on/off, yes/no) will toggle the selection.
Pressing the “A” and “B” buttons on options with variable numerical choices (ie. temperature values, time settings)
will increase and decrease the selected amount. Pressing the “C” button upon completion will forward you to the next
step.
The “D” button can be used to revert to the previous menu.
