AQ255 AND AQ257 SERIES EXPANSION ZONING PANELS
There are three levels of settings in the AQ25A's memory –
CURRENT, FACTORY and SETUP.
• CURRENT settings are the settings that are currently
displayed in any of the menus and are the settings that the
Control Panel uses to operate. Any time a value is changed
in any of the menus, the CURRENT settings are changed
and these new settings are instantly used by the Control
Panel.
• FACTORY settings are the default values loaded at the
factory and are the starting point for programming the
AQ25A, AQ251 or AQ252 Control Panel. These values are
permanently stored in memory and cannot be over-written
or erased. The Control Panel can be restored to factory
settings through the RESTORE FACTORY option in the
SAVE / RESTORE sub-menu. A warning prompt,
RESTORE FACTORY—ARE YOU SURE?, displays and
YES or NO must be chosen before proceeding. If YES is
selected, the FACTORY settings are be copied to the
Control Panel's CURRENT settings and the Control Panel
begins to operate with these values immediately.
• SETUP settings are the specific settings for this installation
which an installer has saved after the Control Panel is set
up and operating well. These are saved for future recall, in
case the system's settings are inadvertently changed.

— To save this installation's settings for the first time, go to
the Control Panel's EQUIPMENT SETUP > SAVE/
RESTORE sub-menu. Position the indicator arrow (←)
beside SAVE SETUP and press OK. This saves the
current system settings to the SETUP values.
— To retrieve the SETUP values at any time in the future,
go to the EQUIPMENT SETUP > SAVE/RESTORE
sub-menu and select RESTORE SETUP to load those
values into the AQ25A as the CURRENT settings. The
system will now operate according to these retrieved
settings.
— If the current settings are modified after a RESTORE
SETUP operation is performed, simply select SAVE
SETUP again to overwrite these new settings into the
SAVE settings memory.
CAUTION
If you change any system settings after a
RESTORE SETUP operation, you change the
current settings that the Control Panel (AQ25A,
AQ251, or AQ252) uses as its basis of operation.
