The
Cool-it II, like all ATM products, is
designed to operate continuously, drawing only a few watts
of
electrical power.
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
'Y
or
A buttons to
change to the desired temperature. After a few seconds, the
new

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.

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
'Y
buttons to set the desired
differential.
The
display will return to showing system temperature after a few
seconds; the new differential temperature has been stored.
For
your convenience, here are some commonly-used Fahrenheit temperatures
and their Celsius equivalents, rounded to the nearest whole degree:
75F = 24C
85F = 29C
95F = 35C
80F
= 27C
90F
= 32C
100F = 38C
*Pressing the A
or
'Y
buttons again will cycle the display through the following
codes: P1, P2, P3, P4, PS, P6, and back to
PO.
Many
of
these codes refer to
parameters used in heating
and
refrigeration systems,
not
in cooling systems.
Should any be adjusted accidentally, restore them to their factory settings:
