Installation Instructions
The Cool-wall fan panels are mounted to supply fresh
air
,
or
extract heated air, from
the video panel (or other heat-producing system). Select the location for the thermal
probe, the small silver-colored cylinder attached to the control board located between
the center fans. Position the probe where
it
can sense the heat from the equipment,
plug the power supply into an
AC
outlet that is always live and plug the power
supply's output lead into the connector attached to the control unit.
Note
that
the
small
temperature display
on
the
control
board
reads in degrees Celsius,
not
Fahrenheit
When the temperature
at
the thermistor reaches 32 degrees C, (about 90F - see
below) the fans will begin to turn. The fans will stop when the temperature falls below
29C (about 85F). A hair dryer can be used to check for proper operation.
To
change the temperature
at
which
the
fans
tum
ON, press the SET button on the
control board momentarily. The display will blink. Press the •
or
A buttons to
change to the desired temperature. After a few seconds, the new temperature will be
stored.
To
change the temperature
at
which the fans
tum
OFF, decide how many degrees
below the turn-on temperature you wish the fans to stop, called the differential. (The
factory setting is 3 Celsius degrees,
or
about 5 Fahrenheit degrees.)
To
change the
differential:
Hold the SET button for 5 seconds.
PO
will be displayed.* Press the A button once to
change the display to
P1,
then press SET again. The present differential temperature
will be displayed. Use the A and
•buttons
to set the desired differential. The display
will return to showing system temperature after a few seconds; the new temperature
differential has been stored.
