LED INDICATION

The LEDs above all keys are designed to
indicate the state of each function, whether it
is active or the display is indicating the mode.

For HI 8711 and HI 931501 only

Each LED can be in one of the following
states:

A) Light stays on

The mode is displayed
on the LCD but is not
active. E.g. alarm set
point is displayed but
the alarm contact is
open.

B) Light Blinking 25% On, 75% Off

The mode is not dis-
played on the LCD but
the mode is active. E.g.
alarm contact is closed
but the alarm set point
is not displayed.

C) Light Blinking 75% On, 25% Off

The mode is active and
being displayed.

D) Light Off

The function is neither
active nor displayed.
