1.DOWN arrow. Generally used to scroll down or incre- ment through a group of choices.

2.SET. Used to accept a setting that normally becomes stored in memory. Also used together with the arrow buttons.

3.UP arrow. Generally used to scroll up or increment through a group of choices.

4.Regenerate. Used to command the controller to regenerate. Also used to change the lock mode.

Note: If a button is not pushed for thirty seconds, the controller returns to normal operation mode. Pushing the Regenerate button immediately returns the controller to normal operation.

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.
