*Factory Setting
**Adjust Jumper Setting (+, NOM, --) is applied to both Cooling and Heating
Note 1: HP Mode Jumper provides a 10% reduction in airflow when in Comfort position and a call for low or high cooling is
present with the ”O” line off. This feature is to provide lower airflow for running in HP Heating Mode if desirable.
Note 2: DEHUM mode (24VAC on DEHUM terminal) provides a 20% airflow reduction during cooling calls.
Note 3: Low Heat ESP is a result of High Heat ESP (-- is decrease in rise).
Note 4: High and low heat rise values are approximate air temperature change from return air temperature when at factory
default settings.

Max CFM (L/s) based on 600 FPM (3.0 m/s)
NOTE: Disposable filters are typically rated at 300 FPM (1.5 m/s).
These filters only allow half the airflow when compared to 600 FPM
(3.0 m/s) filters.
