Calculating Air Flow
ere are circumstances where it may be desirable to know the air
ow delivery through the duct
system, such as when estimating the amount of air ow available for
air conditioning. is can be done by direct measurement with elec-
tronic or sloped manometers and velometers, or by counting the
number of times the amber CFM LED on the control board ashes.
Each ash signi es 100 CFM; count the ashes and multiply by 100
to determine the actual CFM delivered (for example: 10 ashes x 100
= 1000 CFM). Or use the formula in the next column.
CFM =
Output
1.085 x
∆T
where:
• CFM is airfl ow in cubic feet per minute;
• ∆T is the temperature rise; and
• Output is the furnace output capacity from
the rating plate
.
NOTE: Output will vary directly with the input. If the
actual input is below the stated input, the output will
be reduced in the same ratio (93%).

WARNING
DISCONNECT THE ELECTRICAL SUPPLY TO THE
FURNACE BEFORE ATTEMPTING TO CHANGE THE
BLOWER SPEED. FAILURE TO DO SO COULD RESULT
IN ELECTRICAL SHOCK RESULTING IN PERSONAL
INJURY OR LOSS OF LIFE.
is unit is factory set to run at the middle of the heating tempera-
ture rise range as listed on the rating plate. e cooling speed is set
to the maximum air ow designated in the model number.
ree sets of 4 position movable jumpers are provided for Heat,
Cool, and Adjust taps for a variable speed motor. ese tap jumpers
apply signals to the ECM motor without other interaction with the
control board.
