Airflow performance includes 1" washable filter media.
*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.

Airflow % is of High Cool airflow demand determined from SW2--5/6 Table 1
Airflow resumes to 100% after on delay time is completed
Airflow stops (or switches to continuous fan speed) after off delay time is completed
