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 SAVE.
• Furnace Air Flow: Comfort or Efficiency. Default = Comfort
• Low Heat Rise: On or Off. Default = Off
6.3.3.2. AC/HP Airflow
NOTE: 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 when used with a geothermal
heat pump.
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
