Light Hourmeter
This display only shows the hours the fluorescent lamps have been lit
and how many hours remain until you receive a warning to replace the
lamps.
Change Light Life
In this option, you can set the hourmeter before you get the replace light
warning. For most fluorescent lamps, the output of light decreases at a
constant rate. Typically, after 6,000 hours of operation the lamp will
output less light than it did when it was new. This option allows you to
set the warning at what ever level you prefer, in 100 hour increments.
Reset Light Clock
This option resets the light hourmeter to 0 after the fluorescent lamps
have been replaced.
Blower Operation
This selection allows you to choose to operate the blower in Smart-Start,
Manual Touchpad, or in Night-Smart modes.
Smart-Start
When the “Smart-Start” option is selected, the blower will turn on every
time the sash is opened. When the sash is closed, the blower will shut
off.
Manual Touchpad
When the “Manual Touchpad” option is selected, the blower must be
turned on and off at the touchpad.
Night-Smart
When the “Night-Smart” option is selected, the blower will turn on every
time the sash is opened. When the sash is closed, the blower speed will
decrease, to deliver 20-30% of the volume of air during normal
operation.
Cabinet Set Up
These selections allow for the customization of the display and the cabinet
operation.
Units of Measure
When equipped with the optional airflow sensor, this option allows you
to select the air velocity units of measure. When “Metric” is selected, the
air velocities will be displayed in meters-per-second. When “US” is
selected, the velocities will be displayed in feet-per-second.
