19 Auxiliary Alarm Switch
The control is equipped with a 24VAC Aux Alarm to
be used for a condensate switch install (designated by
CONDENSATE IN/OUT on the control). By default, the
connected AUX switch is normally closed and opens when
the water level in the evaporator coil base pan reaches an
undesirable level. The control responds by displaying a ""
error code and turning off the outdoor condensing unit. If the
AUX switch is detected to be in the closed position for 30
seconds, normal operation resumes and the error message
is no longer displayed.

The air handler includes three on-board push buttons
allowing users to navigate indoor and outdoor system
menus. The Right and Left buttons allow the user to scroll
through the main menus and to then scroll through available
options within specific menus. The Center button is used
to enter into a main menu and to then permanently select
options within those menus.
NOTE: After scrolling to the desired option within a menu,
that option may be flashing on the 7-segment displays. This
indicates the option has not been officially selected. Press-
ing the Center button two times will select that option. The
first press will stop the flashing. The second will make the
selection official and return you to the main menu.
