6.3.3.1. Furnace Airflow
Selects the airflow of the furnace when heating. EFFICIENCY is the airflow used
to meet specified ratings, COMFORT is a decreased airflow used to increase the
output air temperature and provide increased comfort.
For the Low heat rise option, set to ON if the system contains a bypass humidifier.
The ON setting will increase the furnace low heat airflow.
After the selections are made, touch

6.3.3.2. AC/HP Air Flow
For Geothermal Heat Pumps, this option will be shown as ’Geo HP’ airflow. 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 : 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 (or EFF1) 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 (or EFF2) airflow is a fixed airflow used to achieve specified
ratings – no dehumidification airflow reduction is performed. This is nominally 350
