Programming Conventions
The 700 series controller is programmed using the
buttons on the keypad. The programming instructions are
described two ways whenever a section has keypad
input.
First, a table shows simplified instructions. Second, text
follows that describes the action. In each table:
"Action" lists the event or action desired.
"Keys" are listed as:
UP for up arrow
DOWN for down arrow
SET for set
REGEN for regeneration
"Duration" describes how long a button is held down:
P/R for press and release
HOLD for press and hold
X sec for a number of seconds to press the button
and hold it down
"Display" calls out the display icons that are visible.
