EXTENDED AIR FLOW DATA - F4FV VARIABLE SPEED MODELS
Normal
The normal setting provides a 30-second ramp-up from zero
airflow to full capacity and a 30-second ramp-down from full
capacity back to zero airflow. Whenever there is a change in
airflow mode, such as a call for cooling or a change from low
heat to high heat, the motor will take 30 seconds to ramp
from one speed to the other.
Humid
The humid setting is best-suited for installations where the
humidity is frequently very high during cooling season, such
as in the southern part of the country. On a call for cooling,
the blower will ramp up to 50% of full capacity and will stay
there for two minutes, then will ramp up to 82% of full capac-
ity and will stay there for five minutes, and then will ramp up
to full capacity, where it will stay until the wall thermostat is
satisfied. In every case, it will take the motor 30 seconds to
ramp from one speed to another.
Dry
The dry setting is best suited to parts of the country where
excessive humidity is not generally a problem, where the
summer months are usually dry. On a call for cooling the
motor will ramp up to full capacity and will stay there until the
thermostat is satisfied. At the end of the cooling cycle, the
blower will ramp down to 50% of full capacity where it will stay
for 60 seconds. Then it will ramp down to zero. In every case,
it will take the motor 30 seconds to ramp from one speed to
another.
Temperate
The temperate setting is best suited for most of the country,
where neither excessive humidity nor extremely dry condi-
tions are the norm. On a call for cooling, the motor will ramp
up to 63% of full capacity and will stay there for 90 seconds,
then will ramp up to full capacity. At the end of the cooling
cycle, the motor will ramp down to 63% of full capacity and
will stay there for 30 seconds, then will ramp down to zero. In
every case, it will take the motor 30 seconds to ramp from
one speed to another.
CFM/TAP SELECTION - F4FV
1
1. Both the “COOL” and the “ADJ” tap must be set for the cooling CFM.
2. Fan only CFM = 63% of high speed cooling.
3. Low speed cooling used only with two stage outdoor units.
(Speed is preset to 65% of high speed).
4. Dehumidification speed is 85% of cooling speed.
5. When operating in both heat pump and electric heat modes, the CFM will
be whichever is greater.
6. CFM indicator light flashes once for every 100 CFM (i.e., 12 Flashes is
1200 CFM).
