6.3.3.2.
AC/HP Air Flow
This option elects the airflow of the furnace when cooling, heat pump heating, and
dehumidification.
The
QUIET
airflow means the minimum cooling airflow that the system can safely
run (typically 300 CFM/ton). Use this setting if duct noise is a severe problem. Note
that duct sweating in high humidity environments could become an issue at low
airflows. The
COMFORT
airflow means airflow is varied depending on humidity
and temperature demand settings. This selection enables the full dehumidify and
comfort capabilities of the system. The
EFF325
airflow is a fixed airflow used to
achieve specified ratings – no dehumidification airflow reduction is performed.
This is nominally 325 CFM/ton, but will vary if a 2--stage outdoor unit is used. The
EFF350
airflow is a fixed airflow used to achieve specified ratings – no
dehumidification airflow reduction is performed. This is nominally 350 CFM/ton,
but will vary if a 2--stage outdoor unit is used. The
MAX
airflow is a fixed 400
CFM/ton. No dehumidification airflow reduction is performed.
The dehumidify airflow, when set to
NORMAL
, the airflow is allowed to adjust to
a minimum to satisfy the dehumidification call. When set to
HIGH
, the minimum
airflow during the dehumidify mode is increased to reduce duct and register
sweating. Also the airflow increases minimum airflow during normal cooling
operation to help reduce duct sweating.
After the selections are made, touch
