The BSC has three modes and two of which, normal mode and quickstart mode, can be used in daily activity.

enabled.

Quickstart mode allows the user to activate the blower and light by simply moving the sash window to the
operating position. In this mode, all alarms and interlocks are enabled.

alarms are disabled and all interlocks are defeated.
3.2.3.桠Admin Settings
The admin menu allows you to change both FAN and ADMIN PIN. The reset blower, filter and UV hour meter
(if present) functions are usually used after the blower, filter or UV lamp is changed as they can easily serve as
an indication to the user on when the BSC needs maintenance. The reset default function will return the
options in the settings menu to their factory settings.
3.2.3.1.桠 New ADMIN PIN (Default 0009)
ADMIN PIN restricts access to some of the more delicate menu functions, namely admin and field calibration,
which should only be accessed by qualified personnel. User must enter a four-digit ADMIN PIN before
accessing these menus.
ADMIN PIN can also be used to switch to maintenance mode from error condition.
3.2.3.2.桠 New FAN PIN (Default 0000 - DISABLED)
FAN PIN restricts access to fan control and some parts of the menu, settings and set mode. User must enter
the four-digit PIN before switching the fan on or off. This feature prevents unauthorized personnel from
accessing critical control sections. It will also prevent unauthorized shutdown of the BSC when continuous
operation is required. FAN PIN is also needed to disable the alarm when the sash is fully raised and cleaning
needs to be performed.
It is recommended that the FAN PIN be issued only to personnel authorized to use the BSC. With FAN PIN, the
user can access admin and set mode parts of the menu.
