EFF 350 -- fixed airflow used to achieve specified ratings –
no dehumidification airflow reduction. This is nominally 350
CFM/ton, but will vary if a 2--stage outdoor unit is used.
MAXIMUM -- 400 CFM/ton. No dehumidification airflow re-
duction.
Multistage Heat Pumps Cooling Airflow
COMFORT (default) -- cooling airflow is varied depending on
humidity and temperature demands settings. This selection en-
ables the full dehumidify and comfort capabilities of the system.
When COMFORT is not selected, the unit will not run reduced
airflows for dehumidification.
EFFICIENCY -- Airflow to achieve specific ratings. At maxi-
mum stage, this is nominally 350 CFM/ton, but will vary with
stage and outdoor temperature.
MAXIMUM -- 400 CFM/ton.
Dehum Airflow
NORMAL (default) -- When equipment is running to dehu-
midify, the airflow is allowed to adjust to a minimum to satisfy
the dehumidification call.
HIGH -- Minimum airflow during the dehumidify mode is in-
creased to reduce duct and register sweating.
Furnace Airflow (Capacity) Limiting
The following settings allow the installer to restrict the fur-
nace within certain minimum and maximum airflows. These
airflows are converted to capacities. The Min and Max limits
are determined by the equipment size.
Min CFM (only appears with modulating furnaces)
