Require Password –
Normally it is not required to use a password (i.e. 3 key press sequence of the
blower and hidden key). If the option is turned on, it would be required to
use the correct password to turn on the blower. The default password once
turned on is blower-hidden-blower keys in sequence. The password can be
changed in the blower password option menu.
Allow UV light anytime – (UV Light option not available)
Normally the UV light is interlocked with the window being in the closed
position. For service purposes only, if the function is active, the UV light may
be turned on at any window height.
Note: In addition to the Allow UV light anytime system function, there is a double
redundant UV light window interlock relay. To override the UV light window
interlock relay, the relay itself must also be shorted. (See electrical schematic for
reference).
Manual Blower Restart – Normally when the blower is actively running and a
power interruption occurs. The blower will automatically come back on when
power is restored. If this function is turned off, the blower will not
automatically come back after a power interruption, but would require the
user to press the blower key to restart the blower.
Nite Care –
Normally the Nite Care function is turned off. If selected and turned on, once
the blower is actively running. Upon closure, the blower will continue to run
at a calibrated lower speed level to keep the workzone interior sterile. The
PresurFlow™ will indicate(s) blinking green LEDs along with green LED above
blower key. The fluorescent light will turn off (blue LED above light key will
blink if window closure turned it off) and become inoperable; however the UV
light can be used.
