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.
Note: If turning off the password option, you must also select the no password menu
item (see section 6.1.8.3)
Allow UV light anytime –
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.
Low Flow –
Normally the 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 maintain a negative airflow. The PresurFlow™ will indicate(s) blinking
green LEDs along with green LED above blower key.
Disable PresurFlow™ -
If this function is active, the digital pressure sensor and alarm function are turned off.
Temporary Low Flow -
When this option parameter is turned on and the other requirements below are met,
the blower key (when held for 5 seconds) will toggle blower between normal and Low
Flow blower speed. The Low Flow blower will time out, based on the Auto Timer
duration for Low Flow without a blower key press and the blower speed will revert
back to normal.
In addition to turning this option on the following requirements must also be met
• Temporary Low Flow Option must be selected
• Password Option must be selected
• Window is at normal height and blower is running
•
Low Flow Option must be selected
•
Low Flow blower auto timer must be set for a minimum of 15 minutes.
Disable audible alarms / audible key feedback
Normally audible alarms from the PresurFlow™ monitor and audible key feedback are
present to provide an audible sound to the user. If this function is active, all audible
sound will be silenced when the control system is in normal run mode.
Audible sound will still occur in any service/calibration menu function.
